Make A Fist, See For Yourself
Increased body temperatures spreads to the skin via blood circulation. The skin surface of the hand, due to exposed high arterial flow, responds easily and steadily to changes in mean body temperature. Results are repeatable and steady with +/- 0.5 degrees.
Try it yourself. Make a fist. You can clearly see the arteries in the hand leading to the fingers. The closeness of these arteries to the skin wall makes this area ideal for self-scanning and produces excellent results across a vast majority of the population.
Why the Wrist Beats the Head in Temperature Scanning
- Virtually no perspiration vs. heavy perspiration of forehead which interferes with thermal scanning
- Reduced hair on wrist/fist vs. possible hair interfering with forehead thermal scanners
- No makeup on wrist/fist vs. eye and skin makeup on head thermal scanning
- No interference by hats and face covering, which is commonplace with head thermal scanning
- Easy self-serving without danger of personnel exposure prior to results
The back of the hand has ideal arterial blood flow, which accurately correlates to mean body temperature. Research confirms, the back of the hand has one of the most steady readings which is ideal for thermal scanning.

Why FeverWarn is Best Among Thermal Scanners
There’s Lots of Ways to Measure Temperature…But Few Include All the Advantages of FeverWarn.
Accuracy. Reliability. Simplicity. Safety
FeverWarn is ideally designed and positioned to offer advantages in self-service monitoring, proven accuracy, data storage and USB outputs all at a reasonable price and easy installation over alternative thermal scanners. Like all IR scanners outdoor use is not recommended and it should be installed inside.
Forehead Thermal Scanner
Most Infrared forehead temperature guns, although accurate and affordable, require human interaction and do not allow for proper social distancing. Sun, makeup, and varying heights also add to the difficulties of measuring the temperature from the forehead. Not for outside.
Uses same infrared technology as FeverWarn. Compromised by forehead perspiration, hair, makeup and head coverings not found on wrist measurements
Accuracy depends on perspiration, makeup, hair and positioning distance
Head covering would need to be removed
Human intervention required
No data outputs for provable future compliance defense
No data outputs for auxiliary devices
FeverWarn Infrared Fist Artery Thermal Scanner
FeverWarn uses the same infrared sensors as other thermal scanners, but has been specifically designed for fist/wrist artery temperature scanning, which is not subject to high perspiration, significant hair, head coverings or make-up. Not for outside.
Manufactured in the USA
Consistent accuracy not compromised by forehead perspiration, make-up, hair and head coverings

Camera Based Thermal Scanner
Thermal scanning cameras, while accurate, are expensive, and in some cases where facial recognition is used can cause privacy concerns. Not for outside.
No human intervention required
Some models provide data outputs for future compliance defense
Some models provide data outputs for auxiliary devices
Most use similar infrared sensor principle as FeverWarn
Accuracy depends on exposure to UV sunlight, makeup, facial coverings and distance and resolution of camera
Not recommended for crowd scanning unless very high resolution camera, should primarily be used for individual scanning as with FeverWarn.
Typically require separately sold computer interface not included

Frequently Asked Questions
Q. What is FeverWarn?
- A. FeverWarn is an IoT-based, skin temperature scanning system from MachineSense. The current models scan skin temperatures at entrances to act as your virtual screening tool without the need for personnel to hold IR scanning devices and compromise social distancing rules. The data is then captured and can be integrated into any third-party IT system.
Q. What does the FeverWarn system include?
- A. The system includes a bracket for the easy mounting of one infrared, touchless temperature sensor to be installed in either a fixture or entryways so that infrared radiations from a human body can be measured for elevated temperatures. The sensor measures the surface temperature by detecting infrared radiation energy and wavelength distribution. The IR temperature probe consists of an optical system, photoelectric detector, amplifier, signal processing, and output module. The optical system collects the infrared radiation in its field of view, and the infrared radiation energy is converted into corresponding electrical signals when converging on the photoelectric detector. It operates from 3.3 to 5 VDC. Data is sent to a data hub via BLE/I2C at a rate of up to 1000 samples/sec.
- Data hub/Intelligence IoT Edge Module. This device reads all the signals from the sensor, calibrates the reading, and signals whether a high-temperature reading is detected. An LED light indicates that result. The alarm can be integrated with an automated-door system via a relay. The module can also be connected to a cloud application where the user can see all the statistics recorded over the past three months.
- LED lights signal go/no-go from the temperature reading or an upgraded model utilizes speaker announcements that provide instructions (user-customizable) to individuals passing through the system.
- CrystalBall Software Platform. Each company can register their company name and product serial numbers in the MachineSense CrystalBall software platform. Each scanned entrant is recorded with a time stamp. This access is included free of charge on all software included models for one year. After one year, it can be renewed at $10/month or $100/year. (Software access is not available on all models.)
Q. What are the power requirements?
- A. 110/220V, 60Hz AC power supply will power FeverWarn.
Q. Can I integrate FeverWarn to automated doors and gate systems?
- A. Yes. Feverwarn’s Edge module offers a relay signal to integrate with automatic openings. Feverwarn sends an ON/OFF relay based on a go/no go temperature via USB. A customer can purchase an appropriate USB relay converter for their relay system to automate door operation.
Q. How does FeverWarn differ from other thermal scanners?
- A. FeverWarn is a patent-pending system developed by an IoT company MachineSense, LLC. and its partner Novatec, Inc., a US manufacturer with more than 50 years of experience in industrial equipment. The following are the unique features of FeverWarn when compared to other products.
- It is easy to install at doorways, entrances, and employee check-in systems, etc.
- It can be integrated with automated doors via relay and is offered with Modbus and UART.
- Alarm and statistics can be sent to the cloud. Deployers can receive alerts with a timestamp via SMS text messages or emails.
- Alarms and other statistics are available over REST API to integrate with any existing ERP systems.
- For large scale deployments, it offers an auto-calibration system for easy maintenance.
- It is calibrated using the human body to maintain calibration easily.
Q. What are the typical applications?
- A. FeverWarn’s initial products are designed especially for doorways at building entrances. FeverWarn assures employees and customers of an efficient screening process without violating social distancing standards. Custom configurations for other applications can be discussed with our engineering group.
Q. How do you calibrate FeverWarn?
- A. Each sensor is factory calibrated. If field calibration is required, customers can conduct their calibration by manual or automatic calibration process using the “MachineSense IoT Support” mobile app. In manual calibration mode, the human body temperature must be taken as a reference. In auto-calibration mode, the reference temperature will be taken from the calibrator by the device automatically. The calibration certificate will be readable from the web/mobile app. For bulk installation and operation, customers can purchase an auto-calibrator for automatic calibration of the system.
Q. What are the disadvantages of handheld forehead scanning?
- A. Handheld forehead scans can be compromised by forehead perspiration, hair, makeup, and head coverings. These known issues are not associated with fist/wrist scanning.
Also, human intervention is required for forehead scanning eliminating the opportunity to maintain proper social distancing.
No automatic data outputs are available for provable compliance and defense, if needed. No data outputs are available to connect with auxiliary devices for automatic opening of doors, gates, or integration with employee card systems.
Q. What are the disadvantages of thermal imaging?
- A. Non-contact thermal imaging has several restrictions. Although skin temperature is a good indicator of a core body temperature, scanning skin temperature automatically can be difficult. The reliability of scanning the skin temperature depends on factors such as the use of makeup, skin color, sweating, exposure to ambient temperature, etc. Depending on those factors, error margins can be increased. That’s why the FDA recommends that if an elevated temperature is detected, a proper contact thermometer should be used to confirm a fever.
Q. Why is the fist used for temperature?
- A. Fever is a rise in core body temperature. Blood vessels carry the temperature to the skin. That’s why the skin on top of the arteries is the best location for scanning a non-contact temperature. The fist has several arteries under the skin surface
Q. How does the fist correlate to the forehead scanning?
- A. Fist and forehead temperatures go up and down with respect to body temperature exactly in the same way. If the fist temperature is known, the core body temperature can be predicted in the same way as the forehead.
Q. What are the advantages of FeverWarn cloud storage vs. local storage?
- A. Cloud storage offers significant advantages over local storage systems, including:
- If you have multiple scanning systems in numerous locations, all the data will be stored and viewed in a single app. This provides easy access to a centralized system.
- Email/SMS texts will be sent to designated persons as soon as an elevated temperature is detected.
- Software features will be automatically updated.
- Data can be seen anywhere, anytime, as opposed to a mobile app where data can only be seen when close to the device.
Q. Where is FeverWarn manufactured?
- A. Baltimore, Maryland – USA
Q. Which cloud service is used with FeverWarn?
- A. FeverWarn is built on the Microsoft® Azure Cloud platform. The servers are in Virginia, USA.
