MLX90614 IR Thermometer Infrared Temperature Sensor Module Single and Dual Zone

Description

Tutorial: How to Use MLX90614 IR Thermometer

This infrared thermometer measures temperature without contact, ideal for environmental monitoring and safety projects.

What you need

• Arduino Uno or compatible
• 5V power supply cable
• Thermostat for testing (optional)
• Digital thermometer for comparison (optional)

Steps

1. 1. Installation: Download and install the MLX90614 library.
2. 2. Connection: Connect VCC to 5V, GND to GND, SDA to SDA and SCL to SCL.
3. 3. Code: Add the following code.
4. 4. Testing: Use a digital thermometer to compare values.
5. 5. Configuration: Set the measurement mode (single or dual range).
6. 6. Debugging: Check the temperature in various environmental conditions.
7. 7. Calibration: Check the datasheet if necessary.
8. 8. Usage: Integrate into your project.

Example code

```
#include <MLX90614.h>

MLX90614 sensor;

void setup() {
  Serial.begin(9600);
}

void loop() {
  float temp = sensor.getTempC();
  Serial.println(temp);
  delay(1000);
}
```

Mini project

Create a temperature warning with an LED that turns on when the temperature exceeds a certain limit.
