Building Arduino projects with multiple sensors can unlock powerful environmental monitoring, automation, and IoT applications. From DHT11 temperature sensors to motion, gas, and light detectors, ...

[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 project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

With just an Arduino board, a DHT11 sensor, and an I2C LCD, you can create a simple yet effective weather station at home. This beginner-friendly project displays real-time temperature and humidity ...

The Apple iPhone brought the benefits of integrated multi-sensor technology to the masses, and while the application of sensors and their associated algorithms has multiplied and changed the world ...

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 ...
