Am2301 / dht21 Product Overview
Am2301 / dht21 digital temperature and humidity sensor is a temperature and humidity composite sensor with calibrated digital signal output. It applies digital module acquisition technology and temperature and humidity sensing technology to ensure high reliability and long-term stability of products. The sensor includes a capacitive humidity sensing element and an NTC temperature measuring element, and is connected with a high-performance 8-bit single chip microcomputer. Therefore, the product has the advantages of high quality, ultra fast response, strong anti-interference ability and high cost performance. Each am2301 / dht21 sensor is calibrated in a humidity calibration room. Calibration coefficients are stored in OTP memory in the form of program. These calibration coefficients are called during the processing of detection signals inside the sensor. Single line serial interface makes system integration simple and fast. Ultra small size, low power consumption and signal transmission distance of more than 20 meters make it a good choice for all kinds of applications and even harsh applications. The product is a 4-pin single row pin package. The connection is convenient, and the special packaging form can be provided according to the needs of users.
