Microduino-Temp&Hum is a temperature & humidity sensor module. 

It is a temperature and humidity compound sensor with the calibrated digital signal output. The use of special temp&hum sampling technology ensures that the product has a high reliability and excellent long-term stability. Microudino-Temp&Hum consists of a capacitive humidity sensor and a high precision integrated temperature measuring component, connecting with a high performance microprocessor. Therefore, the product has the advantages of excellent quality, fast response, high anti-interference and high comparability in price and etc.

==Development==
===Preparation===
*Make sure you build Microduino development environment. If not, please refer to: [[Microduino Getting started]]
*Core module selection  
**1.Adopt [[Microduino-CoreUSB]] or [[mCookie-CoreUSB]]. 
**2.Adopt [[Microduino-Core]] or [[Microduino-Core+]] together with [[Microduino-USBTTL]] for program download. 
===Program===
*Open program " read_simple " in the libraries. 
[[file:mCookie-readSimple.JPG|thumb|800px|center]]
*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.

*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]]
[[file:upload.JPG|thumb|800px|center]]
*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.  
===Project===
* '''[[Temperature & Humidity Sensor]]'''
