Step 1: Programming With Arduino IDE ESP8266
Our module is programmed using the Arduino IDE.
Components and materials required for testing
1 FTDI Serial converter- usb
Step 2: Connecting the Arduino and Sensor DS18B20
1 The esp8266 module has 2 gpio and use the GPIO 2 for temperature reception via OneWire.
2 Wireless network parameters are set the code.
3 Sensor connection uses only 2 wires, gnd and OneWire plot, taking into account the connection of resistance
Step 3: Testing
Using the serial debug terminal:
- the correct reading of the sensor from the ESP8266 and the corresponding value.
- Emoncms communication with server and sending JSON from the ESP8266.
The ESP8266 send data and Emoncms platform makes graphics and data processing in real time.
