![]() There’s an add-on for the Arduino IDE that allows you to program the ESP32 using the Arduino IDE and its programming language. The following schematic shows an example for three sensors (you can add more sensors if needed). When wiring the DS18B20 temperature sensor you need to add a 4.7k Ohm resistor between VCC and the data line. Here’s a list of the parts you need to follow this example:ĮSP32 DOIT DEVKIT V1 Board – read ESP32 Development Boards Review and ComparisonĭS18B20 temperature sensor (we’re using 3 sensors in this example) Where to Buy the DS18B20 Temperature Sensor?Ĭheck the links below to compare the DS18B20 temperature sensor price on different stores:ĭS18B20 digital temperature sensor (waterproof version) Operating range temperature: -55oC to 125oCĪccuracy +/-0.5 oC (between the range -10oC to 85oC)įrom left to right: the first pin is GND, the second is data, and the rightmost pin is VCC. Here’s the main specifications of the DS18B20 temperature sensor:Ĭomunicates over 1-wire bus communication Note: there’s also a waterproof version of the DS18B20 temperature sensor. The following figure shows the DS18B20 temperature. The DS18B20 is a great sensor because it is cheap, accurate and very easy to use. This is specially useful for data logging and temperature control projects. ![]() Each sensor has a unique 64-bit serial number, which means you can use many sensors on the same data bus (this means many sensors connected to the same GPIO). The DS18B20 temperature sensor is a 1-wire digital temperature sensor. Introducing the DS18B20 Temperature Sensor
