LM335Z Precision Temperature Sensor TO-92

Description

The LM135, LM235, LM335 are precision temperature sensors which can be easily calibrated. They operate as a 2-terminal Zener and the breakdown voltage is directly proportional to the absolute temperature at 10mV/°K. The circuit has a dynamic impedance of less than 1Ω and operates within a range of current from 450µA to 5mA without alteration of its characteristics. Calibrated at +25°C, the LM135, LM235, and LM335 have a typical error of less than 1°C over a 100°C temperature range. Unlike other sensors, the LM135, LM235, LM335 have a linear output

Here's a step-by-step tutorial:

Step 1: Gather the Required Equipment:

• Arduino Uno board
• LM335Z temperature sensor
• Breadboard
• Jumper wires

Step 2: Understand the LM335Z Temperature Sensor:

• The LM335Z is a precision temperature sensor that provides an analog voltage output proportional to the temperature in Kelvin.
• The LM335Z has three pins: Vout (output), V+ (positive supply), and GND (ground).

Step 3: Connect the LM335Z Temperature Sensor to the Breadboard:

• Insert the LM335Z temperature sensor into the breadboard so that its pins are on separate rows.
• Connect the V+ pin of the LM335Z to the 5V pin on the Arduino Uno using a jumper wire.
• Connect the GND pin of the LM335Z to the GND pin on the Arduino Uno using a jumper wire.
• Connect the Vout pin of the LM335Z to the A0 pin on the Arduino Uno using a jumper wire.

Step 4: Upload the Code and Read Temperature Data:

• Open the Arduino IDE software on your computer and create a new sketch.
• Copy and paste the following code into the sketch:

void setup() {
  Serial.begin(9600); // Start serial communication at 9600 bps
}

void loop() {
  int sensorValue = analogRead(A0); // Read analog value from A0 pin
  float temperature = (sensorValue * 0.00488 - 0.5) * 100; // Convert sensor value to temperature in Celsius
  Serial.print("Temperature: ");
  Serial.print(temperature);
  Serial.println(" °C");
  delay(1000); // Delay for 1 second
}

• Verify and upload the code to your Arduino Uno.
• Open the Serial Monitor in the Arduino IDE to view the temperature data.
• You should now see the temperature data in Celsius being displayed in the Serial Monitor.

That's it! You have successfully connected an LM335Z temperature sensor to an Arduino Uno and read temperature data. You can now use this data for further processing or display as needed in your project.
