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).

Development

Preparation

Program

  • Open the "test" program in the libraries.
  • 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.

  • 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.
