This guide reads temperature from multiple DS18B20 temperature sensors with ESP32 using Arduino IDE. We’ll wire the sensors on the same data bus to the ESP32

The DS18B20 is a temperature sensor that can be used in various simple projects. This part uses the 1 wire (I2C) bus and you can connect multiple sensors up to your Arduino. The part is also relatively low cost and only requires an additional 4k7 pull up resistor. In the example below we shall make a […]
