AM2302 Product Overview

AM2302 Digital temperature and humidity sensor is a temperature and humidity composite sensor containing calibrated digital signal output.It uses dedicated digital module collection technology and temperature and humidity sensing technology to ensure that the product has extremely high reliability and excellent long -term stability.The sensor includes a capacitive sensor wet component and a NTC temperature measurement element, and connects to a high -performance 8 -digit single -chip microcomputer.Therefore, the product has the advantages of excellent quality, super fast response, strong anti -interference ability, and extremely high cost performance.Each AM2302 sensor is calibrated in the extremely accurate humidity school laboratory.The calibration coefficients are stored in the OTP memory in the form of a program. The inside of the sensor must call these calibration coefficients during the processing signal processing process.Single -line serial interfaces make system integration simple and fast.The super small volume and extremely low power consumption, the signal transmission distance can reach more than 20 meters, making it the best choice in various applications and even the most harsh applications.The product is a 4 -needle quotation foot packaging.Easy to connect, special packaging forms can be provided according to user needs.
