Microduino-LM75

Language	English

Microduino-LM75 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). 文件:Microduino-LM75 I2C.jpg 600px Document Schematic: 文件: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. 文件:MCookie-LM75Test.JPG 800px 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.

Select the right board and COM port, compile and download. You can refer to AVR Core：Getting started 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.
