Air quality sensor designed for battery operation and central data collection in HomeAssistant.

Introduction

This project contains all things needed to setup e.g. a sensor grid for monitoring temperature, humidity and CO2-levels in several rooms in your home and maybe outside.

The sensors are built from scratch with an ESP32 as compute unit and a sensirion SHTC3 for temperature and humidity monitoring. For additional CO2-level measurement a sensirion SCD30 can be used. The software is based on platform-io and is therefore easy to build and deploy.

The sensor data is sent via W-LAN and MQTT protocol to home assistant on the backend server. Home assistant is at first place a home automation system. But one part of automation is to collect data from sensors. We therefore use this mechanisms and the corresponding Web-UI to have a flexible way to store and visualize the collected data.

A very similar but more generic project is ESPHome

Getting started

The whole project consists of the following parts:

• Backend Software
• Hardware
• Device Software

See the linked sub-pages for further instructions.

Usage

Indoor - SCD30

Outdoor - SHTC3

Versioning

There exists no version numbers, releases, tags or branches. The master should be considered the current stable release. All other existing branches are feature/development branches and are considered unstable.
