Ambient Sensor

What is it?

This project is a ambient environment sensor that gathers the luminosity, temperature, humidity, and pressure. This data is transmitted in real time to my Home Assistant server via MQTT over Ethernet.

Why?

I wanted to explore real-time adjustments of lighting, and window coverings to maintain constant light levels in a room, which requires high sample rates (multiple samples per second) for responsive adjustments.

When I started this project there were no high-sample rate luminosity sensors for home automation. The devices that did exist either had low sample rates (minutes vs milliseconds), or were designed for scientific applications.

Project Contents

  • AmbientSensor_Code - firmware source code
  • AmbientSensor_HomeAssisant - sample configuration for use with HomeAssistant
  • AmbientSensor_KiCAD - schematic and PCB
  • AmbientSensor_Peripheral - schematic and PCB for peripheral sensors
  • AmbientSensor_Media - photos
