In addition, it is equipped with a programmable frequency response range of 0.1Hz to 10Hz, making it suitable for a wide variety of applications.

AMG8834 Working Principle

The AMG8834 is an integrated thermopile array module, which uses the thermoelectric detection principle to measure temperatures. The module contains an 8x8 array of 64 thermopiles, and each thermopile consists of a pair of junctions that generate voltage when heated or cooled, proportional to the temperature difference between them. Since the thermopiles are arranged in a grid, the module can detect areas of higher or lower temperatures, providing an accurate thermal image of the environment.

The AMG8834 can be connected to a host system via an SPI/I2C interface, which allows for temperature data to be digitalized and processed to generate a thermal image. The module is powered by a single 3.3V power supply and can be programmed via I2C bus. It also has active and standby modes, which allow the user to select the power efficiency level according to their application requirements.

The AMG8834 is a powerful and versatile temperature sensor, which can be used in a variety of applications that require a wide sensing range and reliable temperature measurement. Its temperature resolution and the programmable frequency response range make it a suitable choice for many applications, including human and animal body temperature detection, environmental monitoring, surface temperature measurement and thermal imaging.
