Development
Preparation
Program
- Open program " read_simple " in the libraries.
- include <AM2321.h> ; Call temperature and humidity AM2312 library function.
- AM2321 am2321; Define am2312.
- am2321.read(); Acquire sensor's temperature and humidity data.
- Serial.print(am2321.temperature/10.0); Process output temperature values.
- Serial.print(am2321.humidity/10.0); Process output humidity value.
Hardware Buildup
- Connect sensor with Sensorhub IIC interface via the connection wire.
Microduino-Sensorhub
mCookie-Hub
- Connect the core module, Sensorhub and AM2312 together to a computer via a USB cable.
- Select the right board and COM port, compile and download. Please refer to: AVR Core：Getting started
- Open Arduino IDE, select File→Examples→Microduino→Sensor_Tem_Hum_AM2321→read_simple program examples, choose the right board from Tools→Board and compile.
- Choose the right port number from Tools→Serial Port in Arduino IDE and download program.
- Open serial monitor after download. The console will print the current temperature and humidity values.
Application
Applied in environment temperature and humidity detection, capable of controlling air conditioner and fan as a temperature and humidity switch.
