**2.6 IR thermal camera sensor**

Thermal imaging is a tool that uses heat energy to detect the surface of an object. Currently, thermal imaging technology has been used in various fields, including engineering, health, military, environment, to health.

IR Thermal Camera is a non-contact sensor device that can detect heat or infrared energy and convert it and convert it into electrical energy or electronic signal, which can then produce a thermal image. In addition to generating thermal images, these electronic signals can also be used to perform temperature calculations or measurements.

Visualization of AMG8833 sensor is shown in **Figure 5**. The AMG8833 is a thermal imaging camera sensor with an 8×8 pixel thermal sensor family manufactured by Panasonic. The AMG8833 only supports I2C and has a configurable interrupt pin, which can be activated when each pixel is above or below the required threshold.

The detector on the AMG8833, as shown in **Figure 6**, consists of a thermopile sensor using MEMS (micro electro mechanical system) technology which is arranged in an 8×8 pixel array. A thermopile is a temperature sensor composed of a layer of the silicon film, which contains many thermocouples so that the infrared energy

emitted from the object will be absorbed and converted into electrical energy. After turning into electrical energy, signal processing is carried out. In the signal processing process, first, amplify the electrical energy or electrical signal obtained, then use an analog-to-digital converter (ADC) to convert it into a digital signal. Then the digital signal enters the control system for calculation, comparison, and correction so that the output temperature is Celsius.
