Outside temperature and humidity sensor (DHT11)

The step-down converters on the left, and the terminal blocks for 12V, 5V and grounds

5V single channel relay to switch on/off power for ventilation fan

PWM MOSFET module LR7843 to control LED stripe

Arduino UNO Rev3 with all cables connected

Mean Well LRS-50-12 to power Arduino and all related components

Distribution box at the back of the enclosure, allows to disconnect components mounted on the top cover in case it needs to be removed

The ventilation fan and opened fan doors

Cables routing at the back of the enclosure

Cables routing at the left (all stuff installation) side of the enclosure with all the electronics

Inside temperature and humidity sensor (DHT22)

MQ2 gas sensor
