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
