AM2301 / DHT21product description

AM2301 / DHT21 digital temperature and humidityCalibrated sensor is a digital signal comprisingTemperature and humidity sensors signal output of the complex.It is an application-specific module collects digital technology and temperature and humidity sensing technologyTo ensure that products with high reliability and excellent long-term stability. An electrical sensor comprising aAllowformulasenseElement and a wetFor NTCTemperature measuring element, and with a8-bit, single-chip phaseconnection. Therefore, the product has excellent quality, fast response, anti-interference ability, high cost and other advantages. Each AM2301 /DHT21Calibrate sensors extremely accurate calibration humidity chamber. The calibration coefficients stored in the OTP program memory, the internal processing of the sensor detection signal to call these calibration coefficients.singleWire serial interface, system integration becomes simpler and quicker. Ultra-small size, low power consumption,Signal transmission distance up to 20 meters,Making all kinds of applications and even the most demanding applications is the best option is. productfor 4Pin single row pin package.Easy connection,Special packages can be provided according to user needs.
