This library can be used for human thermal detection. There are examples to read temperature readings as quickly as possible and read the temperature pixels, output the temperature readings to all pixels to be read by a Processing visualizer from the MLX90640 IR array.

seeed_arduino_mlx9064x's Introduction

Seeed Arduino MLX90640

The inspiration for this product came from Melexis's mlx90640 and Melexis's mlx90641. This relies on the driver written by Melexis.

Introduction

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/wide-angle has an FOV(Field of View) of 55°x35°/110°x75°.

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, I2C protocol is used to get the low-resolution image from the camera.

This module connects the MCU with the I2C interface. However, it needs an MCU which 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 a good performance to process the complex data from the IR sensor camera.

Note:

Visualization The visual effect is as follows, you can use the following command to install his upper computer on the raspberry PI or PC

pip3 install seeed_python_ircamera

#PortName is like COM1,COM2 in Windows system.
#MLX90640 is an optional chip type , MLX90640 or MLX90641 can be supported for now.
