How to send Sensair S8 CO2 sensor readings to InfluxDB with an esp8266 devboard
install this library in ArduinoIDE first
https://github.com/jcomas/S8_UART
Now write the code to your esp device with Arduino IDE, this will send readings every 60 seconds, you can change this by editing the line 'Serial.println("Wait 60s"); delay(60000);;' to whatever you want.
The Sensair S8 is factory set to default to 400ppm CO2, as the current world wide level is around 420ppm I have added 20 in this line 'sensor_db.addField("co2_value", sensor_s8.co2 + 20);' you can of course change this if you wish.
Below is a screenshot from my InfluxDB dashboard.
