Description
The HR202L is a moisture-sensitive resistor designed using organic polymer materials that respond reliably to varying humidity levels. It offers a wide sensing range, fast response times, and excellent long-term stability, making it suitable for both indoor and outdoor applications. Its compact design allows easy integration into weather monitoring systems, HVAC, and smart home devices. The HR202L does not require heating for self-cleaning, and its anti-pollution capability enhances performance in harsh environments.
