Simple JSON API using an NodeMCU ESP-12E module

environment-tracker-arduino

Arduino (NodeMCU ESP-12E module) code for the sensors API

Hardware

Setup

Sensors

• BME280 (temperature, pressure, humidity)
• HTU21DF (temperature & humidity; but more accurate than the BME280)
• TSL2561 (illuminance; full spectrum, ir spectrum & visible spectrum)

Output

When browsing to the IP of the module you will see a similar output as below.

{
  "illuminance": {
    "visible": 905,
    "full": 1255,
    "ir": 347
  },
  "temperature": 24.51,
  "humidity": 37.49,
  "pressure": 1027.82
}

But there's also other routes to fetch raw values separately & disable / enable the LED.

• GET /
• GET /illuminance/full
• GET /illuminance/visible
• GET /illuminance/ir
• GET /temperature
• GET /humidity
• GET /pressure
• POST /led // body payload: enabled: 0 | 1
