CoViD-19 IR Thermometer
Now that students around the world are starting to return to school, many people are talking about screening them before they enter the school premises, to help stop the spread of COVID-19. The same is true in many work places too. Whether you like the idea of screening or not, it is already a reality in many places and it is inevitable that it will be introduced in some schools, somewhere. The less obtrusive and time consuming it is the better.
IR thermometers are being touted as a quick and effective way to help screen students. With an IR thermometer teachers will be able to scan students to see if they have an elevated temperature or not, which is one of the key indicators of fever, which is an indicator of COVID-19. If this sounds a bit tenuous perhaps it is, but there are not a lot of other options right now, and this is quick, low risk and can be applied to large numbers of people. A quick Google search will show that IR sensors are already being used in many contexts to screen for COVID-19.

Because IR thermometers are in short supply and becoming very expensive due to demand, we have created an IR thermometer that you can use by simply connecting XinaBox xChips together. Designed with speed in mind, the XinaBox IR Thermometer will detect when someone has a high temperature on the surface of their skin - a potential indicator of a fever. It only takes a few seconds per person and there is no contact with the hardware, so cross-contamination is not an issue. This is not a medical instrument: what it does, and what all IR scanners do, is measure the temperature of an area of skin on an individual from several inches away.
All you will need to build your IR Thermometer is an OD01 OLED Display, SL19 IR Temperature Sensor, CC03 Cortex M0+ Core, IP03 Programmer, PU01 USB (Type A) Power Supply, XC10 xBUS Connectors and XS02 xPDI Connectors. Alternatively, you can replace the IP03 and PU01 with the IP02 Programmer to program and power the device. You might already have a CS11, CW01, or CW02 core: the SL19 will work with all of them. And if you have one of our bridges the SL19 can be accessed from a Raspberry Pi, BBC micro:bit and a range of other devices too.
Once connected and programmed, the device will show you the temperature at the top of the OLED display. If the surface measured (e.g. a student's forehead) has a normal temperature, it will display HEALTHY under the temperature and a green light will shine on the CC03; and if the student has an elevated temperature (e.g. if they have a fever) it will display FEVER and a red light will shine. Where the result is FEVER this should be taken to mean that the temperature that has been measured on the surface exposed to the sensor is higher than 35.6deg C.
