This is a compact sensor node featuring useful sensors to integrate with Home Assistant

I made this project because I wanted to try and make an integrated PCB with multiple sensors, and use the bare I2C modules. A Home Assistant sensor node is something that would benefit from being compact, using a custom PCB, and is also something I would use in my life for more advanced automations.

• Custom PCB for compact wiring
• Temperature/Humidity Sensor (HDC2010)
• Light Sensor (OPT3001)
• Compact size (63mm x 36mm x 20 mm)
