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.

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