1、Product Overview

AM2315 capacitive humidity sensing digital temperature and humidity sensor is one that contains the

temperature and humidity combined sensor has been calibrated digital signal output. Special temperature and

humidity acquisition technology, to ensure that the product has high reliability and excellent long-term

stability. The sensor includes a capacitive sensor wet components and an integrated high-precision

temperature measurement devices, and connected with a high-performance microprocessor. The product has

excellent quality, fast response, strong anti-jamming capability, and high cost.

AM2315 communication standard I2C communication. I2C communication standard communication

timing, the user can be directly linked to on the I2C communication bus, no additional wiring, simple to use.

Transmission of digital data output directly compensated by the temperature, humidity, temperature and

Check (CRC) and other digital information, the user does not need the digital output for the second

calculation, and no need for temperature compensation of the humidity, you can get an accurate temperature

and humidity information . Product of four leads, convenient connection, special packages according to user

needs.
