MLX90640 Infrared Camera Module 55° FOV

Description

What is the MLX90640? The MLX90640 is a 55° field of view infrared camera module that allows temperature measurement and thermal profile detection in electronic projects, particularly with Arduino. It’s ideal for non-invasive temperature sensing applications. Features Infrared Camera Module 55° FOV 32×24 pixels For Arduino projects What does it do? The MLX90640 can be used to create thermal monitoring systems, such as integrating a 16×2 LCD display to show real-time temperatures. It is compatible with Arduino and can be used in various electronic and IoT projects. Tutorial: How to use MLX90640 The MLX90640 is an infrared camera module with 32×24 pixels, ideal for thermal monitoring and temperature sensing projects. What do you need? MLX90640 Module Arduino Uno LCD Display 16×2 10kΩ Resistor Steps 1. Connect the MLX90640 to Arduino using these pins: SDA -> A4, SCL -> A5, VCC -> 5V, GND -> GND. 2. Connect a 10kΩ resistor between VCC and SDA to protect the I2C bus. 3. Start the Arduino code to initialise the module. 4. Read thermal data using the MLX90640 library. 5. Display data on an LCD screen. 6. Check the datasheet for update frequency and accuracy. 7. Test temperature detection in various environmental conditions. 8. Adapt the code to improve precision and accuracy. Example Code “`cpp #include #include #include LiquidCrystal_I2C lcd(0x27, 16, 2); MLX90640 mlx; void setup() { lcd.init(); lcd.backlight(); mlx.begin(); } void loop() { float* temp = mlx.getTemperatures(); lcd.clear(); lcd.print(“Temp: “); lcd.print(temp[0]); lcd.print(“C”); delay(1000); } “` Mini-project Create a simple thermal monitoring system using the MLX90640 and an LCD display 16×2. In 30 minutes, you can have a system that displays temperature at a specific point. Common mistakes Forgetting to connect pins correctly. Using a resistor other than 10kΩ. Not checking accuracy parameters on the datasheet. Omitting delay between temperature readers.
