Description:
HR202 Humidity Detection Sensor Module is a reliable and cost-effective humidity sensing solution designed for detecting and measuring relative humidity levels in the surrounding environment. This module uses the HR202 humidity-sensitive resistor, a high-performance polymer humidity sensor, which changes its resistance according to the surrounding humidity.
Features:
1. High-sensitivity humidity detection using HR202 sensor
2. Dual output: Analog (continuous humidity reading) and Digital (threshold trigger)
3. Onboard LM393 voltage comparator for precise digital output
4. Adjustable sensitivity using onboard potentiometer
5. Power and output indicator LEDs for easy monitoring
6.Compact and easy to use with microcontrollers
7. Suitable for DIY electronics, automation, and weather-based projects
