AM2302 Product Overview
AM2302 digital temperature and humidity sensor is a calibrated digital output signal containing 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.
Includes a capacitive sensor element and a sense of wet NTC 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 AM2302 sensors are extremely accurate calibration of humidity calibration chamber. Calibration coefficients stored in the form of a program OTP memory, internal sensor detection signals in the process to call these calibration coefficients. Single-wire serial interface, the system integration becomes simpler and faster. Ultra-small size, low power consumption, signal transmission distance up to 20 meters or more, making all kinds of applications and even the most demanding applications is the best selection.
Products for the 4-pin single row pin package.
Easy connection, special packages can be provided according to user needs.
