[](https://github.com/HON95/prometheus-esp8266-dht-exporter/releases)
|
|
|
|
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-based board: [WEMOS D1 Mini](https://wiki.wemos.cc/products:d1:d1_mini)
|
|
|
|
DHT sensor: [Wemos DHT Shield](https://wiki.wemos.cc/products:retired:dht_shield_v1.0.0) (DHT11)
|
|
|
|
## Software
|
|
|
|
- [Arduino IDE](https://www.arduino.cc/en/Main/Software)
|
|
- Download and install.
|
|
- [esp8266 library for Arduino](https://github.com/esp8266/Arduino#installing-with-boards-manager)
|
|
- See the instructions on the page.
|
|
- [DHT sensor library for ESPx](https://github.com/beegee-tokyo/DHTesp)
|
|
- Install using the Arduino library manager.
|
|
- The Adafruit one didn't work for the WEMOS D1.
|
|
|
|
## Building
|
|
|
|
This uses the Arduino IDE.
|
|
|
|
1. Copy `config.default.h` to `config.h` and fill inn the details.
|
|
1. Set the correct settings for the board.
|
|
- WEMOS D1 Mini uses board "WeMoS D1 R2 & mini".
|
|
1. Build and upload using the Arduino IDE.
|
|
|
|
## Version
|
|
|
|
See `src/version.h`.
|
|
|
|
It's set manually since no build tools (or CI) other than the Arduino IDE is used.
