lm335 Arduino: A Simple Guide to Connect and Measure Temperature
Article Summary:
If you’re looking to connect an LM335 temperature sensor with your Arduino board, you’ve come to the right place. In this article, we’ll show you how to connect LM335 to Arduino Uno, Mega, and Nano boards. We’ll also provide you with sample code snippets to get you started with measuring temperature using LM335.
Introduction:
LM335 is a precision IC temperature sensor that can be easily connected to an Arduino board to measure temperature accurately. It provides an output voltage that is proportional to the temperature measured in Kelvin. In this article, we’ll walk you through the steps of connecting LM335 to Arduino and measuring temperature using it.
Connecting LM335 to Arduino:
To connect LM335 to an Arduino board, you’ll need the following components:
1. LM335 Temperature Sensor
2. Breadboard
3. Jumper Wires
4. Arduino Board (Uno, Mega, or Nano)
Follow these steps to connect LM335 to Arduino:
1. Connect the LM335’s Vout pin to Arduino’s Analog Input pins (A0 for Uno, A0-A15 for Mega, A0-A7 for Nano).
2. Connect the LM335’s GND pin to one of the GND pins on Arduino.
3. Connect the LM335’s Vs pin to the Arduino’s 5V pin.
Measuring Temperature Using LM335:
Now that you’ve connected LM335 to Arduino, you can use the analogRead() function to read the voltage coming from LM335 and then convert it into temperature values using the formula:
Temperature = (analogRead(A0) * 500.0) / 1024.0;
You can then print the temperature values on the Arduino Serial Monitor using the Serial.print() function.
Sample Code Snippet:
Here is a sample code snippet that you can use to read temperature values from LM335 and print them on the Serial Monitor.
void setup() {
Serial.begin(9600);
}
void loop() {
float voltage = analogRead(A0) * 5.0 / 1024.0;
float temperature = (voltage – 2.73) * 100.0;
Serial.print(“Temperature: “);
Serial.print(temperature);
Serial.println(” °C”);
delay(1000);
}
Conclusion:
LM335 is a simple yet effective way to measure temperature using Arduino. By following the steps outlined in this article, you can easily connect LM335 to Arduino and start measuring temperature values. We hope this article has been helpful to you in your quest to connect LM335 to Arduino and get started with temperature measurements.
