I'm using Raspberry pi 3 model B for some college project with HC SR-04 ultrasonic for distance measurement. Since the sensor is using sound wave, which is depends on the velocity of sound and the velocity of sound is depends on the temperature of the environment. I have question:
- Raspberry pi 3 have temperature monitor, can I use it for another program?
- Does the temperature sensor measure CPU temperature only?
I know there is a lot of temperature monitor project using sensor and Raspberry pi, but if the built-in temperature monitor can do that, why don't I use it.
