1. Product overview
AM2302 Wetmine capacitance digital temperature humidity module is a temperature and humidity composite sensor containing its own calibration digital signal output.It uses dedicated digital module collection technology and temperature and humidity sensing technology to ensure that the product has high reliability and long -term stability.The sensor includes a capacitive sensor wet component and a high -precision temperature measurement element, and connects to a high -performance 8 -digit single -chip microcomputer.Therefore, the product has the advantages of quality, ultra -fast response, strong anti -interference ability, and high cost performance.Each sensor is calibrated in the extremely humid school laboratory.The calibration coefficients are stored in a single -chip microcomputer in the form of a program. The inside of the sensor must call these calibration coefficients during the processing of the detection signal.Standard single bus interfaces make the system integration simple and fast.The super small volume and extremely low power consumption, the signal transmission distance can reach more than 20 meters, making it a good choice for various types of applications or even harsh applications.The product is 3 lead (single bus interface) connection.Special packaging forms can be provided according to user needs.
