Description:

AM2302 digital temperature and humidity module is a digital output signal
containing a calibrated temperature and humidity combined sensor. It uses a
dedicated digital modules capture technology and the temperature and humidity
sensor technology to ensure that products with high reliability and excellent long-term
stability. Sensor includes 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. 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.
