[Edward], creator of the Cave Pearl project, an underwater data logger, needed a way to measure temperature with a microcontroller. Normally, this problem is most easily solved by throwing a ...

Recent Arduino projects are blending AI-assisted coding, advanced thermal and environmental sensors, and cloud connectivity. Tutorials now show how to build systems with MLX90640 infrared cameras, ...

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

As connected as we are, reliable and affordable internet is still a luxury in the far reaches. [kohleick’s] country home is not just remote; with temperatures dropping to -30C in the winter, it’s ...

To make a remote temperature sensor with the LTC2970, run two different currents (ILOW and IHIGH) through the transistor and measure VBE at both currents (VBE_LOW and VBE_HIGH). The difference between ...
