LinkMejor DHT22/AM2302 Digital Temperature and Humidity Sensor Replace SHT11 SHT15

Overview

• AM2302 digital temperature and humidity sensor is a calibrated digital signal output temperature and humidity composite sensor. It uses a dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure that products with high reliability and excellent long-term stability.
• The sensor includes a capacitive sensing element and an NTC temperature sensing element, connected to a high-performance 8-bit microcontroller. Therefore, the product has excellent quality, fast response, anti-interference ability, cost-effective advantages.
• Each AM2302 sensor is calibrated in a very accurate humidity calibration room. The calibration coefficients are stored in OTP memory in the form of programs that the calibration coefficients are invoked within the sensor during signal processing.
• Single-wire serial interface, the system integration becomes simple and quick. 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.
• Products are 4-pin single row pin package, easy to connect.
