This project based on the DS18B20 - ESP32 one Wire Bus Application video and blog ESP32 one Wire Bus Application – DS18B20 section article, to use ESP32 to send the temperature of DS18B20 to Node-RED through the serial port. Three modes are designed in the code, DS18B20_ON, DS18B20_OFF and Node-RED modes.
the ESP32 code is placed on my blog :
