Microduino-LM75 is a digital temperature detection sensor.

==Features==
*Adopt LM75 temperature sensor with optional addresses.
*High accuracy and sensitivity;
*Low consumption, long product life and high stability;
*Wide operation range;
*Small and easy to install.

==Specification==
*Electrical specification
**Operation voltage: 2.8V～5.5V；
**Input device
*Tech parameters
*Accuracy: 0.125℃
*Measurement range: -55℃～+125℃；
*Size
**Size of the sensor: 5mm*5mm，
**Size of the board: 20mm*10mm
*1.27mm-pitch 4Pin interface;
*Connection method
*Interface: IIC
* Pin description: GND, VCC, signal 1and signal 2. Since the output signal is IIC signal, it needs to use IIC interface to receive signals. Microduino-LM75 can be connected to the pin (1 or 2). , which can be connected the pins (10,1,12) of the Sensorhub with the corresponding pins(A6,A2,A0).

==Document==
*Schematic: '''[[File: Microduino_LM75.Zip]]'''

==Development==
===Preparation===
*Make sure you build Microduino IDE or refer to: [[Microduino Getting started]]
*Core selection
**1. Adopt [[Microduino-CoreUSB]] or [[mCookie-CoreUSB]] as the core.
**2. Adopt [[Microduino-Core]] or [[Microduino-Core+]] as the core plus [[Microduino-USBTTL]] as the program download module.

===Program===
*Open the "test" program in the libraries.
[[file:mCookie-LM75Test.JPG|thumb|800px|center]]
*include <lm75.h> Use the library functions of Microduino-LM75.
*TempI2C_LM75 termo = TempI2C_LM75(0x48,TempI2C_LM75::nine_bits); Define TempI2C_LM75
*termo.setResolution(TempI2C_LM75::ten_bits); Set displaying as decimal digits.
*Serial.print(termo.getTemp()); Display output temperature

===Hardware Buildup===
*Connect Microduino-LM75 to the IIC interface of Sensorhub with a wire.

* Connect the core, Sensorhub and the Microduino-LM75 to a computer with a USB cable.
* Select the right board and COM port, compile and download. You can refer to [[AVR Core：Getting started]]
[[file:upload.JPG|thumb|800px|center]]

*Open Arduino IDE, select File→Examples→Microduino→Sensor_Tem_LM75→test program examples, choose the right board from Tools→Board and then compile.
*Select the right port from Tools→Serial Port in Arduino IDE after compiling, then download program.
*After download, you can open the serial monitor. The console will print configuration information of Microduino-LM75 and displays the current temperature value circularly.

==Application==

Microduino-LM75 is suitable for environment temperature detection, which can be used as temperature switch to control an air conditioner or electric fans.
