The assumption is that any properly wired AMG8833 module can be used to follow along in this project, however, the functionality cannot be promised. The AMG8833 from our shop has also been tested and is used for this tutorial. The reason being - the RPi 4 has the fastest processor, which will result in faster output from the real-time visualization (more on this later). The Raspberry Pi model technically does not matter, but we used and chose the RPi 4 Model B board for testing. The project is quite simple in the parts list and wiring requirements, as it only requires the RPi and AMG8833 module:ĪMG8833 Thermal Imager - $60.00 This tutorial uses the AMG8833 infrared array wired to a Raspberry Pi 4 computer communicating via the I2C bus to approximate temperatures of objects via non-contact radiation measurement. The wiring, testing, and analysis of the AMG8833 will be explored here, with a real-time thermal camera as the final output. In this tutorial, a Raspberry Pi is used to interface with the AMG8833, with Python acting as the programming language. The AMG8833 is useful for applications in thermal imaging, heat transfer analyses, human temperature monitoring, heating and air condition management, industrial control, and other applications in non-contact temperature measurement. It also operates at 3.3V and 5V, at a sample rate of 1Hz-10Hz, with an approximate temperature resolution of 0.25☌ over a range of 0☌ to 80☌. The AMG8833 contains an onboard lens that limits the viewing angle of the sensor to 60-degrees, which results in a sensing region useful for objects in the mid-field (as opposed to far-field or near-field). The Grid-EYE communicates via the I 2C bus, which also makes it compatible with Raspberry Pi and Arduino right out of the box. The sensor contains an 8x8 array of infrared thermopiles, which approximate the temperature by measuring the infrared radiation being emitted from emissive bodies. The AMG8833 is a 64-pixel temperature sensor developed by Panasonic under its Grid-EYE® product line.
