BLACK DHT21 Temperature And Humidity Sensor Capacitive DHT-21 DHT22 Temperature & Humidity Sensor Temperature Controller 3 Pin Cables Leads For Arduino

Descriptions: DHT21 AM2301 Digital Temperature & Humidity Temperature Sensor

The Am2301 dht21 Digital Temperature and Humidity Sensor is a combined temperature and humidity sensor with a calibrated digital signal output.We use dedicated digital module acquisition technology and temperature and humidity detection technology to ensure high reliability and excellent long-term stability.The sensor consists of a capacitive humidity sensing element and an ntk temperature measuring element and is connected to a high performance 8-bit single chip microcomputer.Therefore, the product has excellent quality, ultra-fast response, anti-interference function, cost-effectiveness and so on.Each am2301 / dht21 sensor is calibrated in a highly accurate humidity check room.The calibration factors are stored programmatically in otp memory and these calibration factors are recalled by the sensor during the processing of the detected signal.The single-line serial interface makes system integration easy and fast.Ultra-low volume, very low power consumption and signal transmission distances of over 20 meters make it ideal for all kinds of applications and the most demanding applications.
