Weatherproof Stainless Steel LM35 Temperature Sensor

Description

What it is

The stainless steel LM35 waterproof temperature probe is a thermal sensor suitable for Arduino projects and outdoor applications. This component offers a reliable solution for temperature measurement in humid or outdoor environments.

Features

• LM35 Waterproof Temperature Probe
• Stainless Steel

What it is for

The LM35 probe can be used to create a digital thermometer with Arduino. By connecting the probe to the microcontroller and writing a sketch, it is possible to display the temperature in real-time.

Tutorial: How to Use LM35 Waterproof Temperature Probe

The stainless steel LM35 waterproof temperature probe is ideal for precise measurements in humid or outdoor environments. This simple and reliable component fits perfectly into beginner Arduino projects.

What you need

• Arduino Uno
• Jumper wire
• Computer with Arduino IDE software installed

Steps

1. Connect the LM35 probe to the analog pin A0 of the Arduino using a jumper wire.
2. Open the Arduino IDE software and create a new sketch.
3. Insert the example script to read data from the LM35 probe.
4. Upload the sketch to the Arduino microcontroller.
5. Start the serial monitor in Arduino IDE to view the measured temperatures.

Example code

const int tempPin = A0;
void setup() {
  Serial.begin(9600);
}

void loop() {
  float voltage = analogRead(tempPin) * (5.0 / 1023.0); // Verifica sul datasheet per il range di tensione
  float temperatureCelsius = voltage * 100; // Verifica sul datasheet per la conversione da volt a gradi Celsius
  Serial.println(temperatureCelsius);
  delay(1000);
}

Mini project
