Product Description
The HR202 Humidity Detection Sensor Module is a compact and efficient solution designed to detect and monitor ambient humidity levels in real-time. Based on a resistive humidity sensing element, this module provides stable and reliable performance for a wide range of environmental conditions.
This module comes equipped with an onboard comparator circuit, allowing it to provide a digital output signal based on a user-defined humidity threshold. The sensitivity can be easily adjusted using the onboard potentiometer, making it suitable for customized humidity control applications.
It features indicator LEDs for both power and output status, enabling quick visual feedback during operation. The module is designed for seamless interfacing with microcontrollers such as Arduino, ESP8266, and other embedded systems.
Due to its compact size and easy mounting design, the HR202 module is widely used in automation systems, weather monitoring setups, and smart home applications. It can also be used to trigger relays or alarms when humidity crosses a predefined level.
With low power consumption and fast response time, this sensor is an excellent choice for students, hobbyists, and engineers working on environmental sensing and control systems.
