Temperature Sensors – Analog and Digital Output

Thermoresistors and other temperature sensor solutions have been used in a wide variety of applications for a long time. These solutions are able to accurately detect temperature in a variety of environmental conditions. The AMG8833 infrared array temperature sensor provides a new dimension to temperature sensors, due to its ability to provide digital output.

Application Field and Working Principle

The AMG8833 is used in a variety of applications ranging from home appliances, industrial automation, automotive, and consumer electronics. Its applications range from monitoring thermal energy in factories and workshops, to thermal imaging in medical equipment. The AMG8833 is also an ideal choice for monitoring the environment of living spaces, as it can detect both environmental and human body temperatures.

The AMG8833 temperature sensor utilizes an array of 8 x 8 thermopile elements to detect temperatures in its fixed field of view (FOV). Its thermopile elements detect energy from infrared radiation emitted from a body or object within its field of view and convert it to an electrical signal. This signal is then sent to the IC, where it is amplified and processed by advanced algorithms. As a result, the AMG8833 provides digital output in the form of a 64-bit array, with each element in the array representing the temperature of a single pixel in its FOV.

The AMG8833 features a wide detection range of -40°C to +125°C. It has a variable output range of 0°C – 80°C with a 0.25°C resolution. The integrated signal processing block of the AMG8833 allows for compensation of temperature drift, which helps to ensure accuracy in the output readings. The IC also has a high output frequency of 10 frames per second with low power consumption of just 20mW when operating at 1 frame per second.

The AMG8833 also supports a wide range of communication protocols, making it ideal for integration into various IoT applications. The IC is compatible with both I2C and Serial Communications interfaces, allowing for easy integration into any system. Furthermore, it also supports UART and SPI, providing increased flexibility when connecting to a variety of devices.

Overall, the AMG8833 infrared array temperature sensor is an ideal solution for applications requiring accurate digital temperature readings. It offers a wide variety of features, including a high output frequency, low power consumption, and support for multiple communication protocols. These features make it an ideal choice for temperature monitoring in industrial, automotive, medical, and consumer applications.
