DHT11 Sensor - Digital Humidity Sensor

 DHT11 Sensor - Digital Humidity Sensor 



DHT11 brings very high reliability and excellent long-term durability. The DHT22 has a capacitive moisture sensor and an NTC temperature measuring element that is connected to a high-performance 8-bit microcontroller, resulting in a great quality, super-fast response time, and powerful anti-interference capability and highly cost effective.
