prometheus-arduino-dht-exporter

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

Hardware

Arduino-compatible board: WEMOS D1 Mini (ESP8266)

DHT sensor: Wemos DHT Shield (DHT11)

Requirements

• Arduino IDE (download)
• esp8266 library for Arduino (see instructions)
• Adafruit DHT sensor library (install using the library manager, including all dependencies)

Building

1. Copy config.default.h to config.h and fill inn the details.
2. Set the correct board settings in Arduino IDE:
   • WEMOS D1 Mini uses board "WeMoS D1 R2 & mini", CPU frequency 160MHz and upload speed 821 600.
3. Build and upload in Arduino IDE.
