Product Overview

The AM2301/DHT21 digital temperature and humidity sensor is a combined temperature and humidity sensor with pre-calibrated digital signal output. It utilizes specialized digital module acquisition technology and humidity and temperature sensing technology to ensure the product has extremely high reliability and long-term stability. The sensor includes a capacitive humidity sensing element and an NTC temperature sensing element, and is connected to a high-performance 8-bit microcontroller. Therefore, this product has advantages such as quality, ultra-fast response, strong anti-interference ability, and excellent cost performance. Each AM2301/DHT21 sensor is calibrated in an extremely humid laboratory. The calibration coefficients are stored in the OTP memory in the form of a program, and the sensor internally calls these calibration coefficients during the processing of the detection signal. The single-wire serial interface makes system integration simple and quick. The small size, extremely low power consumption, and signal transmission distance of up to 20 meters or more make it an excellent choice for various applications and even for demanding application scenarios. The product is in a 4-pin single-row pin package. The connection is convenient, and special packaging forms can be provided according to user requirements.

Application scope

HVAC (Heating, Ventilation, and Air Conditioning), dehumidifiers, testing and inspection equipment, consumer products, automobiles, automatic control, data recorders, household appliances, humidity regulators, medical equipment, meteorological stations, and other related humidity detection and control applications.
