Welcome to my Station_meteo project !

This is a home made weather station based on MQTT (IoT transmission protocol) using ESP8266, ESP32 hardware, various sensors and a WeeWX to take care of the database and report generation.

WeeWX and MQTT server (mosquitto) are setup on an Orange Pi PC PLUS (low cost raspberry pi-like)

Sensors are connected directly to the orange pi (barometer) or to the wifi network using very low cost ESP8266 boards.

1. Core architecture

2.Wifi sensors

2.1 Outside Temperature, Humidity, UV and Rain gauge.

A single ESP8266 manage the 4 measurements

Check the dedicated wiki page for more details

2.2 Wind (speed & direction)

The wind speed sensor is based on a Inspeed Vector anemometer.
The Wind direction sensor is custom made.

3. Sensors manages by OrangePi

3.1 Barometer / in Temp

The barometer is built with a MS5611 directly connected to the OrangePi
