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.

==Document==
*Schematic: '''[[File: Microduino_Temp&Hum.Zip]]'''

==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]]'''
