Description

This is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn't require extra components so you can get right to measuring relative humidity and temperature. AM2302 digital temperature and humidity sensor is a calibrated digital signal output temperature and humidity combined sensor. Application-specific digital acquisition module and the temperature and humidity sensor technology to ensure the products with high reliability and excellent long-term stability. The sensor includes a capacitive humidity sensing element and an NTC temperature measurement devices, and connected with a high-performance 8-bit microcontroller. The product has excellent quality, fast response, anti-interference ability, high cost, etc.. Each AM2302 sensors are extremely precise humidity calibration chamber for calibration. The calibration coefficients stored in the form of a program OTP memory, internal sensor, the detection signal process to call these calibration coefficients. Single wire serial interface, system integration becomes quick and easy. Ultra-small , 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. The product is a 4-pin single row pin package.
