LM35 Class Reference

API for the DFRobot LM35 Linear Temperature Sensor. More...

Detailed Description

• ID: lm35
• Name: DFRobot LM35 Linear Temperature Sensor
• Other Names: LM35
• Category: temp
• Manufacturer: dfrobot
• Link: http://www.dfrobot.com/index.php?route=product/product&product_id=76
• Connection: analog

This sensor returns an analog voltage proportional to the temperature of the ambient environment.

It has a range of 2C to 150C.

This driver was developed using the DFRobot LM35 Linear Temperature Sensor

  // Instantiate a LM35 on analog pin A0, with a default analog
  // reference voltage of 5.0
  upm::LM35 *sensor = new upm::LM35(0);
  
  // Every half second, sample the sensor and output the temperature

  while (shouldRun)
    {
      cout << "Temperature: " << sensor->getTemperature() << " C" << endl;
      
      usleep(500000);
    }
