Building a Temperature-Based Control System with Raspberry Pi Pico and DS18B20/HW-506 Sensor In this tutorial, you will learn how to use a Raspberry Pi Pico to create a simple temperature control system that automatically switches a relay based on temperature readings from a DS18B20/HW-506 temperature sensor . This project is perfect for beginners who want to understand how to interface with temperature sensors and control devices such as fans or heaters via relays. Components Needed: Raspberry Pi Pico . DS18B20/HW-506 temperature sensor . Relay module (to control an output device like a fan, heater, or any other electrical appliance). Jumper wires and a breadboard . A computer with Thonny IDE for coding in MicroPython. How the System Works: The DS18B20 sensor continuously measures the room temperature. The Raspberry Pi Pico monitors the temperature and turns on a relay when the temperature rises above 20°C . The relay can be connected to any output device that you want to con...
