Keyestudio EASY plug LM35 Temperature Sensor


It is based on semiconductor LM35 temperature sensor.
A temperature sensor is exactly what it sounds like - a sensor used to measure ambient temperature.
It is effective in the range between 0 degree Celsius and 100 degree Celsius. Sensitivity is 10mV per degree Celsius.
The output voltage is proportional to the temperature.
Note: this module should be used together with EASY plug control board.


  • Connector: Easy plug
  • Power supply: 5V
  • Sensitivity: 10mV per degree Celsius
  • Function range: 0℃ to 100℃

Technical Details

  • Dimensions: 38mm*20mm*18mm
  • Weight: 4.6g

Connect It Up

Connect the EASY Plug LM35 temperature sensor to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.

Upload the Code

Copy and paste below code to Arduino IDE and upload.

void setup()
Serial.begin(9600);//Set Baud Rate to 9600 bps
void loop()
{int val;
int dat;
val=analogRead(0);//Connect LM35 on Analog 0
dat=(500 * val) /1024;;
Serial.print("Temp:"); //Display the temperature on Serial monitor

What You Should See

Done uploading the code, open the serial monitor and set the baud rate to 9600, you should see the analog temperature value.
