Description:
This digital temperature and humidity sensor is a digital signal containing a calibrated outputs composite temperature and humidity sensors . It uses a dedicated digital module acquisition technology and temperature and humidity sensing technology to ensure that the product has a very high reliability and excellent long-term stability. Sensor includes an electrical capacitance typefeeling wet element and a high-precision temperature measurement devices, and with a high-performance 8-bit microcontroller with the connection. So the product has excellent quality, ultra-fast response, anti-interference ability, cost-effective and so on. Each sensor is calibrated in an extremely accurate humidity calibration room. The calibration coefficients are stored in OTP memory in the form of a program, and these calibration coefficients are called internally during the processing of the detection signal. Single- wire serial interface, system integration becomes simpler and quicker. Ultra-small size, very low power consumption, signal transmission distance of up to 20 meters or more, making it the most demanding applications for all types of applications.

Single bus digital signal output: data format

Humidity data bits + temperature data bits + checksums

Sensor Performance Description:

This digital temperature and humidity sensor and AM2303 have the same performance (parameters and procedures are the same), using a different package.

Long-term stability ± 0.3% RH /

Overview

The AM2315 is a digital I2C humidity - temperature sensor that is mounted in a protective housing. It is not waterproof but sufficient to provide some protection to both sensors mounted inside. It use the DS18B20 along with a capacitive humidity sensor. It has it's own controller that provides a I2C interface to both of these sensors. We cannot change the address of device so it only supports one device per I2C bus. It is supplied with two mounting brackets depending on how you want to physically mount the device.

Software

We can test this sensor using the simple sketch as shown below. It requires the cactus.io AM2315 Library to communicate with the sensor.

It reads the temperature and humidity every 2 seconds and then displays it on the console.
