A sophisticated, hackable, 32x24 pixel thermal camera breakout! Use it to monitor the temperature of your CPU or coffee pot, or to build your own heat-seeking night vision camera. Works with Raspberry Pi or Arduino.
It's perfect for building into projects - industrial, scientific, or just fun - and much more affordable than most thermal cameras. Our breakout makes it easy to use the camera with your Raspberry Pi or Arduino, using I2C and 3-6V supply. And it's available in two different fields of view, 55° (standard) or 110° (wide angle) depending on your preference.
The MLX90640 far-infrared camera is an array of 768 (32x24) thermal sensors that can detect temperatures from -40 to 300°C with approximately 1°C accuracy and up to 64FPS! The applications of this camera are manifold: measure the heat or heat dissipation of devices like CPUs, circuit boards, or electrical appliances; use it to identify thermal inefficiencies in your home; or use it for presence detection to identify bodies in complete darkness.
It's also compatible with our fancy new Breakout Garden, where using breakouts is as easy just popping it into one of the six slots and starting to grow your project, create, and code.
Features
- Melexis MLX90640 far-infrared sensor array (datasheet)
- 32x24 pixels
- Field of view: 55°x35° or 110°x75°
- Up to 64FPS
- -40 to 300°C detection with approximately 1°C accuracy
- I2C interface (address 0x33)
- 3.3V or 5V compatible
- Reverse polarity protection
- Compatible with all models of Raspberry Pi, and with certain Arduino models
Kit includes
- MLX90640 breakout
- 1x5 male header
- 1x5 female right-angle header
We've designed this breakout board so that you can solder on the piece of right-angle female header and pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 7, 9).
Software
We've written software in C that you can use to generate images and video from the MLX90640 cameras.
SparkFun also provide an example Arduino/Processing sketch for the MLX90640.
Our software does not support Raspbian Wheezy.
Notes
Dimensions: 19x19x2.75mm (LxWxH).
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- reverse polarity protection
- A circuit feature that helps protect the board if power is connected the wrong way around. It matters because it can reduce the chance of damaging the breakout during wiring mistakes, especially in classroom or prototyping use.
