AM2302 capacitive humidity is a digital temperature and humidity module containing digital signal output has been calibrated temperature and humidity sensor complex. It uses a dedicated digital modules collection technology and temperature and humidity sensor technology to ensure that products with high reliability and excellent long-term stability. Sensor includes a capacitive sense element and a wet-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 calibrated in a very precise humidity calibration chamber. Calibration coefficients stored in the form of a program microcontrollers, internal sensor detection signals in the process to call these calibration coefficients. Standard single-bus interface, the system integration becomes simpler and faster. Ultra-small size, low power consumption, signal transmission distance up to 20 meters or more, making it the best choice for all kinds of applications and even the most demanding applications. For the convenience of three lead products (single bus interface) connection. Special packages can be provided according to user needs.
