According to the datasheet, it also has less noise and greater measurement accuracy.īut for visualization tasks, I would recommend a more “long-range” version B.
And in vain.Ī wider version will be good on self-propelled robots or in security systems (the field of view will be larger). For some reason, at the time of the order, I did not pay attention to these nuances. Which version is best for you? A good question, unfortunately, it came to me only after the module was already ordered and received. It looks like this:Īs you can see, there are two types of boards, with a narrow or wide-angle version of the sensor on board. And it is worth at the time of purchase (end of December 2018) in the region of 5 thousand rubles. All this household is called GY-MCU90640. Apparently, for easier management of the matrix. The Chinese comrades put the MLX90640 on the board with another microcontroller on board (STM32F103). Datasheet for those interested can be downloaded here. The case of the device has only four outputs - two for power, two for communication with the control device via the I2C interface. B - under 55 to 37.5 degrees, respectively. A more stocky design A observes the surrounding world at an angle of 110 (horizontal) by 75 (vertical) degrees. The sensor is available in two versions, the body of which differ in the viewing angle of the matrix. This is not much, but when interpolating an image, it seems like enough to see at least something. Thermal imaging matrix has a dimension of 32 by 24 pixels. Production of a previously unknown company Melexis. What happened from this - I will tell under the cut.Īnd this, in fact, a thermal imaging matrix with a microcontroller on board.
Do not collect yourself an exotic and perhaps even useful thing - a homemade thermal imager? Why not, like, and Raspberry was somewhere lying around.
And then it turned out that quite accessible thermal imaging modules appeared on the famous Chinese website. Winter has come, and with it the task to check the insulating properties of the buildings of the country residence of the villa.
