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 ...

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 ...

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, ...

This video demonstrates how to set up a remote temperature monitoring system using an Arduino Uno R4 WiFi, an LM35 temperature sensor, and the MQTT protocol. The system captures ambient temperature ...

[George Dewar] and his wife live in a typical 1940’s house in New Zealand , which in case you didn’t know, have a little insulation in the ceiling… and nowhere else. Like most, they put up with the ...

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 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 ...
