prometheus-esp8266-dht-exporter

A Prometheus exporter for IoT temperature and humidity measurements, using an ESP8266 (Arduino-compatible) with a Wi-Fi module and a DHT (temperature + humidity) sensor.

Hardware

ESP8266 board: WEMOS D1 Mini (ESP8266)

DHT sensor: Wemos DHT Shield (DHT11)

Requirements

• Arduino IDE
  • Download and install.
• esp8266 library for Arduino
  • See the instructions on the page.
• Adafruit DHT sensor library
  • Install using the library manager, including all dependencies.

Building

This uses the Arduino IDE.

1. Copy config.default.h to config.h and fill inn the details.
2. Set the correct settings for the board.
   • WEMOS D1 Mini uses board "WeMoS D1 R2 & mini".
3. Build and upload using the Arduino IDE.
