Infrared Thermal Camera Sensor (AMG8833)

Overview

The AMG8833 Infrared Thermal Camera Sensor is a compact, high-performance 8x8 (64-pixel) infrared thermal sensor array that enables you to visualize temperature distribution in real-time. This sensor detects infrared radiation from objects and converts it into a temperature map, allowing you to 'see' heat signatures even in complete darkness. With a detection range of up to 7 meters, it's perfect for building your own thermal camera, presence detection systems, or any project that requires non-contact temperature sensing.

Key Features

• 8x8 Pixel Resolution: Provides a 64-point thermal map for detailed temperature analysis.
• Wide Detection Range: Accurately detects heat sources from up to 7 meters away.
• High Accuracy: Temperature measurement accuracy of ±2.5°C, sufficient for most hobbyist and prototyping applications.
• I2C Interface: Easy to connect with popular microcontrollers like Arduino, Raspberry Pi, ESP32, and STM32.
• Compact Design: Small form factor (11.6 x 8.0 x 4.3 mm) for easy integration into your projects.
• Low Power Consumption: Operates at 3.3V, drawing only ~4.5mA, ideal for battery-powered applications.
• Wide Temperature Range: Can measure objects from 0°C to 80°C, covering a broad spectrum of thermal applications.
