Humidity Sensitive Switch Relay Module 5V | Automatic Humidity Sensor Control Relay Board 10A

Humidity Sensitive Switch Relay Module 5V | Automatic Humidity Sensor Control Relay Board 10A 

The Humidity Sensitive Switch Relay Module is an automatic humidity control board designed to turn electrical devices ON or OFF based on surrounding moisture level. The module uses a high-quality HR202 humidity sensor to detect humidity and activates the relay when the preset level is reached.

The trigger level can be adjusted using the onboard potentiometer, allowing accurate control for different environments. This module can directly control AC or DC loads such as fans, humidifiers, dehumidifiers, pumps, lights, and ventilation systems.
