weather-station-public

Description:

This project consists of one to many weather sensors based on an ESP32 control board running FreeRTOS and several cheap off-the-shelf sensors. Readings from the weather sensors are collected by a light computing device (Raspberry Pi Zero 2 W or Linux PC) and displayed on the local network as well as recorded in a MySQL database to be used for forecasting functions.

Instructions:

• Pin connections for the ESP32 based sensors can be found below.
• Detailed setup instructions for Raspberry Pi can be found here
• Detailed setup instructions for Linux PC can be found here
• Be sure to change the NetworkName and NetworkPassword palceholders in the Indoor sketch and the Outdoor sketch to match your network.
