AM2301/DHT21 product overview:
AM2301/DHT21 digital temperature and humidity sensor 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 an NTC 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 AM2301/DHT21 sensor is calibrated in an extremely accurate humidity calibration room. The calibration coefficients are stored in the OTP memory in the form of programs, and these calibration coefficients are called in the sensor's internal detection signal processing. The single-wire serial interface makes system integration easy and quick. Ultra-small size, extremely low power consumption, and signal transmission distance of up to 20 meters or more, making it the best choice for various applications and even the most demanding applications. The product is a 4-pin single-row pin package. Convenient connection, special packaging form can be provided according to user needs.
