Get Nodemcu Temperature Sensor Ds18B20 Pics. Unless you have a small adapter (as seen in the picture above), you will need to. If nil the existing list of sensors in memory is used.
NodeMCU Interfacing with SSD1306 and DS18B20 temperature ... from simple-circuit.com If you get any error. 3v power source, for short term testing 2*1,5v aa batteries. The yellow/data cable should be connected to d4 (in the code this will be described as pin 2).
If the bus has not been searched yet the search performed as well.
.to control the ds18b20 temperature sensor, this sensor follows one wire protocol which means you can connect many sensors as you want to the single pin test the below code to know check whether you can get reading from the temperature sensor with esp8266 or nodemcu.
