Product Description

AM2302 digital temperature and humidity capacitance humidity module is a self contained calibrated digital signal output from the temperature and humidity sensor complex. It uses a dedicated digital modules and acquisition technique of temperature and humidity sensor technology to ensure that products with high reliability and excellent long-term stability. Sensor comprises a capacitive humidity sensing element and a high-precision temperature measurement devices, and with a high-performance 8-bit microcontroller connected. Therefore, the product has excellent quality, fast response, anti-interference ability, high cost and other advantages. Each sensor is extremely accurate calibration of humidity calibration chamber. Calibration coefficients stored in the form of a program of the microcontroller, the internal sensor in the process of the detection signal to call these calibration coefficients. Standard single bus interface, system integration becomes simpler and quicker. Ultra-small size, low power consumption, signal transmission distance up to 20 meters, making it the best choice for all kinds of applications and even the most demanding applications. 3 products for easy lead (single-bus interface) connection. Special packages can be provided according to user needs.
