Nagy pontosságú AM2302 DHT22 digitális hőmérséklet- és páratartalom-érzékelő modul az arduino Uno R3-hoz
High Precision AM2302 DHT22 Digital Temperature & Humidity Sensor Module For arduino Uno R3
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 special 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 single-chip microcomputer. Therefore, this product has the advantages of excellent quality, ultra-fast response, strong anti-interference ability, and extremely high cost performance. Each sensor is calibrated in an extremely accurate humidity calibration room. The calibration coefficients are stored in the single-chip microcomputer in the form of a program, and these calibration coefficients are called during the processing of the detection signal inside the sensor. Standard single bus interface makes system integration easy and fast. The ultra-small size, extremely low power consumption, and the signal transmission distance can reach more than 20 meters, making it the best choice for various applications and even the most demanding applications. The product is easy to connect with 3 leads (single bus interface). Special packaging forms can be provided according to user needs.
