MH13001 10A 220V Mini Digital Air Humidity Control Controller
MH13001 Digital Humidity Controller
Overview
Compact digital humidity controller module
Controls devices based on humidity level (RH%)
Supports automatic ON/OFF switching
Ideal for humidifiers, dehumidifiers, and environmental control
Working Principle
External humidity sensor probe measures RH (%)
Controller compares value with set threshold
If humidity:
Below set value turn ON humidifier
Above set value turn OFF device
Uses relay switching (10A) to control AC loads
