[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 ...

The M5Stack is a development kit particularly suitable for developing IoT applications (see figure 1). It is Open Source and it is compatible with Arduino. It allows creating IoT applications in a ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

The first step is a thermistor, a conceptually simple device: resistance varies with temperature (seriously, how much more simple can a sensor get?). You can measure them by tapping the center of a ...

Arduino has just announced the Arduino Matter Discovery Bundle (AKX00081), an all-in-one development kit designed to help ...

Environmental sensing technology has become increasingly vital in today’s world, where understanding and monitoring air quality and environmental conditions are crucial for sustainability and safety.
