AM2303Product overview
AM2303Digital temperature and humidityThe sensor is a digital signal that has been calibrated.Temperature and humidity combined sensor with number output.It uses the special digital module collection technology and the temperature and humidity sensing technology, to ensure that the product has a high reliability and ecellent long-term stability. The sensor includes a powerVolumetypesenseWet components and aNTCTemperature measuring element, and with aHigh performance 8 bit single chip microcomputerconnect Therefore, the product has ecellent quality, super fast response, strong anti-interference ability, high cost performance. eachAM2303The sensors are calibrated in a highly accurate humidity calibration chamber. The calibration coefficient is stored in the OTP memory in the form of the program, and the sensor is called in the process of the detection signal.singleLine serial interface, so that the system integration becomes simple and quick. Ultra small size, etremely low power consumption,Signal transmission distance of up to 20 meters or more,Make it the best choice for all kinds of applications and even the most demanding applications. productby4Pin single row pin package.Convenient connection.
