Arduino / ESP8266 使用 DS18B20的例程 接线: VDD–5V GND–GND DQ–D7(此处为8266,Arduino连2) 注意:DQ和5V之间需要连接一个4.7k的电阻,或者用两个10k的电阻并联也实现相同的效果。 #include <OneWire.h> #include <DallasTemperature.h> #define ONE_WIRE_BUS 13//8266连接GPIO13即D7,Arduino连接port 2...
You could use something like a piezo buzzer to alert you if the temperature falls outside a certain range for example. Throughout this tutorial, I will show you the basics of connecting the DS18B20 to the Arduino correctly. I will also be adding some LEDs to demonstrate the circuit & code...
Another quick trick is to call an Arduino Sketch to help you. For example, the “discover_fake_DS18B20.ino” code can perform some safe tests and indicates if the sensor shows deviations from authentic DS18B20 (not designed to work with parasitic power). GitHub Link https://github.com/cpetr...
Learn how to publish DS18B20 temperature readings via MQTT with the ESP8266 (NodeMCU) to any platform that supports MQTT or any other MQTT client. As an example, we’ll publish sensor readings to Node-RED Dashboard and the ESP8266 will be programmed using Arduino IDE....
