Description DHT22 Digital Temperature and Humidity Sensor Module Temp Humidity Monitor Sensor AM2302 Replace SHT15 SHT11 for Raspberry Pi 1. Product overview AM2302 Humidity Capacitor Digital Temperature and Humidity Module is a temperature and humidity composite sensor with calibrated digital signal output. It uses dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure that the product has extremely high reliability and excellent long-term stability. The sensor includes a capacitive humidity sensing element and a high-precision temperature measuring element, and is connected with a high-performance 8-bit microcontroller. Therefore, the product has the advantages of excellent quality, ultra-fast response, strong anti-interference ability, and high cost performance. Each sensor is calibrated in an extremely accurate humidity calibration chamber. The calibration coefficients are stored in the single-chip microcomputer in the form of a program, and these calibration coefficients should be called in the process of detecting the signal inside the sensor. Standard single bus interface makes system integration easy and fast. Ultra-small size, extremely low power consumption, and signal transmission distance of more than 20 meters, making it the best choice for various applications and even the most demanding applications. The product is 3-lead (single bus interface) for easy connection. Special packaging forms can be provided according to user needs. 2.
