[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 ...

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 ...

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 hardware setup shown below includes the Arduino Uno R4, a DHT11 sensor, and the built-in Wi-Fi for email alerts. The DHT11 is connected with VCC to 5V, GND to ground, and the data pin to Digital ...

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.

SST Sensing has partnered with Sparkfun to develop a simple to implement solution for single point liquid detection using infrared technology. The solution comprises an Optomax Digital liquid level ...
