Getting temperature readings from different DS18B20 sensors.

For this activity we will be reading temperature values from multiple DS18B20 sensors.

What will you need ?

  • 3x DS18B20 sensors

  • NodeMCU ESP8266 Dev kit board

  • male-to-male jumper wires

  • One 4.7k Ohm resistors

The circuit for the multiple DS18B20 sensors is as follows:
