UV weathering chamber
The goal was to build a chamber to test the durability of wooden parts under UV radiation.
The cabinet contains six UV radiation lamps. The upper part contains all the electronics, control elements and fans.
There is one ballast for every two UV lamps. UV lamps operate on 230V alternating current (AC). The second 5V power supply is for the controller. It has a solid-state relay that turns the UV lights on/off using a microcontroller. I use Raspberry Pi Pico 2 W. The plan is to add a web interface in the future. It has a DHT22 temperature and humidity sensor. It is inside the UV chamber. Also, it has a control circuit for the fans (5V). I also added door sensors to automatically turn off the UV light when someone opens the doors.
