Both narrow-angle and wide-angle panel-mounted thermal array sensors are readily available. AMG8854M01 is a surface mount modular narrow-angle 8px x 8px (64 pixels) high-precision microelectromechanical system (MEMS) IR array, which runs on a standard 5V power supply and uses a simple I 2 C 5 for connection-pin connector (figure 1). This can be easily connected to almost any micro device to read the thermal level in each module (from -21°C to 80°C) with an accuracy of ±3°C.

AMG8834, a low-gain version of 3.3V, I 2C-based on the heat of an 8×8 array in a surface mount reflow package, is also available. Although the multiplexed clock usually only supports two I 2 C slave addresses, it is relatively easy to implement multiple I 2 C ports on a microcomputer. This is what you want to do, because each read is 64 12 Bit calorific value. When scanning using the I 2 C interface, the device provides a selectable rate of 1 or 10 frames per second.

The sensor has two versions; low gain and high gain, which helps the sensor to match the environment. High gain accuracy is better but the temperature detection range is narrow, low gain accuracy is lower but the temperature detection range is wider. The thermal pixels can be read indirectly without an external infrared illuminator. Discrete infrared light sensors with shorter wavelengths usually require infrared illuminators.

To allow you to start testing immediately, a development tool is also provided. The MIKROE-2539 provides a sensor used in the grid-EYE (function of the interface board in Figure 2). However, the interface is very simple, and the engineering laboratory can use a few I/O pins and power connections to quickly get the sensor up and running (Figure 3). Note: When the image plane is ready to download, interrupts can be used to detect notifications.
64 pixels cannot provide sufficient detection range. In this case, Panasonic provides an intelligent interpolation solution that can help expand the working data points, while using only a single Grid EYE can significantly improve the accuracy within the detection range window. Separate sensors are very suitable for entering and exiting the area, and can accurately detect when a person passes through the detection area. Large offices and buildings that require comprehensive coverage must distribute sensors in strategic locations or combine multiple sensors into a larger array.

Although one of the most critical applications is human detection, these sensors cover a variety of other beneficial uses. It can be used in agricultural environments to detect how many cattle leave the fence to graze and how many cattle return. They can also be used in manufacturing test environments to find systems that have overheated and are not operating according to specifications. The debugging system can also use these as alternatives to FLIR cameras.
