Summary
In this chapter, you learned the basics of connecting an IR temperature sensor to a microcontroller board using the I2C serial data transmission protocol. As you could see, the I2C bus is an important part of the IR thermometer that we built in this chapter. This IR thermometer can be effective for checking human body temperature, like a regular thermometer will do. Since the temperature measurement is contactless, this can prevent the human body from touching the sensor and thus avoiding spreading viruses such as SARS-CoV-2.
This touchless thermometer may help to check whether a person has a fever and thus determine (along with other measurements) whether the person has contracted COVID-19. However, the IR temperature measurements explained in this chapter should not be definitive data to determine whether a person has COVID-19.
The next chapter explains another COVID-19-related project about measuring the recommended 2-meter distance between two people using an ultrasonic...
