View Nodemcu Ds18B20 Wiring Background. Wiring multiple ds18b20 sensors to esp8266 nodemcu. Scans the bus for ds18b20 sensors (optional), starts a readout (conversion) for all sensors and calls a callback function when all temperatures are available.

Simple Example: Arduino+ESP8266+DS18B20 | Arduino ... — Simple Example: Arduino+ESP8266+DS18B20 | Arduino ... from i.pinimg.com

I used the same temperature sensor with the arduino and displayed the. If nil, gpio0 (3) is used. После этого заливаю пример с nodemcu.readthedocs.io.

Upload sketch to nodemcu and run sketch.

In addition, the ds18b20 can derive power directly from the data line (parasite power), eliminating the need for an external power supply. On top of the web page project heading is displaced. Common all the vdd pins, gnd pins & signal pins. To use ds18b20 sensors you also need to install dallastemperature library.
