Grove - Thermal Imaging Camera / IR Array MLX90640 55 degree

Grove - Thermal Imaging Camera is a thermal sensor which carries MLX90640 IR Array. The camera can present dynamic thermal images and detect the surrounding temperature from -40℃~300℃. The camera with narrow-angle has an FOV of 55°x35 °.               




We have newly released an upgraded version of this thermal imaging camera with MLX90641 IR array and 110° FOV. Click here to learn more!

Key Features

  • IR Thermal Sensor Array 32X24(MLX90640)
  • 55°x35° FOV(field of view)
  • Temperature measurement range:-40℃~300℃
  • I2C Grove interface


Looking for a thermal sensor that can detect your surround temperature? This IR thermal camera can not only measure the value of temperature around you but also display the thermal imaging figure. So it must be your best choice to monitor the temperature change from this tiny camera.


The IR thermal camera carries a 32x24 array of thermal sensors (MLX90640), it can detect the temperature of objects from feet away with the accuracy of ±1.5℃. In order to obtain the thermal image easily, the I2C protocol is used to get the low-resolution image from the camera. The FOV(Field of View) of this camera is 55°x35°, and the temperature measurement range is -40℃~300℃.


This module connects the MCU with the I2C interface. However, it needs an MCU that has over 20000 bytes of RAM to drive the camera. As a matter of fact, Dev board like Arduino Uno can not be used with this Sensor camera due to its lower ability of calculation. We recommend you to choose Arch Mix as an MCU to control the camera because it really has an excellent performance to process the complex data from the IR sensor camera.


This thermal imaging sensor is also compatible with many Arduino boards and Seeeduino boards which are assembled with SAMD21/SAMD51 like Seeeduino Lotus Cortex - M0. And it also supports all series of Raspberry Pi including Raspberry Pi Zero.

Considering your convenience of using this camera, we have figured out all the libraries like Arduino Library and Python commend in our wiki page, so you can run up this IR camera module easily for just a few minutes.
