HR202L Humidity Sensor without shell

The HR202L Humidity Sensor without shell is a polymer-based analog humidity-sensitive resistor ideal for accurate and cost-effective humidity detection. Designed without a shell, it features a wide sensing range of 20–95% RH and excellent long-term stability. With a typical impedance of 31kΩ at 60% RH (25°C, 1kHz), it offers ±5% RH accuracy, making it suitable for a wide range of applications like indoor air monitoring, agriculture, medical equipment, and industrial systems. Operating on low power (max 0.2mW), it functions optimally between 500Hz–2kHz. Its compact size and reliability make it perfect for integration into both hobbyist and professional-grade humidity control systems.
