Analog Temperature Sensor LM35DZ TO92 Arduino Compatible

Description

Tutorial: How to Use the LM35DZ Temperature Sensor

The LM35DZ sensor is ideal for measuring precise temperatures in Arduino projects. Useful for beginners and intermediates.

What you need

• Arduino UNO
• Power cable
• 10kΩ resistor (to stabilize the signal)
• Multimeter
• Check the datasheet

Steps

1. 1. Connect the sensor to pin A0 of Arduino.
2. 2. Connect the resistor between GND and VCC of Arduino.
3. 3. Download the Arduino-Temperature-Control-Library library.
4. 4. Load the example code ‘Temperature’.
5. 5. Check the temperature with the multimeter.
6. 6. Modify the code to display the temperature in Celsius.
7. 7. Test the sensor with different temperatures.
8. 8. Verify the operation.

Mini project

Build a digital thermometer with the LM35DZ sensor and a 16×2 LCD display in 30 minutes.

Common mistakes

• Connect the sensor to VCC of Arduino without resistor.
• Omit the verification with the multimeter.
• Set code for Fahrenheit instead of Celsius.

Recommended accessories

• Display 16×2 LCD
• Framboreeka one
• 9V battery
• Connection cables
