Sentinel Specification Sheet

The Sentinel connects to commercial camera traps to process captured images and transmit results of animal species detected by a neural network on-device. It includes a custom printed circuit board with a low-power microcontroller (Microchip SAM D21E) and an embedded computer with tensor processing unit (Google Coral SoM) for image processing. The circuit board also includes power management components, a camera trigger detection circuit, and microSD storage for processed image data. Communication modules may include cellular (Blues Wireless), LoRaWAN (Blues Wireless), or satellite (SpaceX) in addition to built-in WiFi. The circuit board is powered by rechargeable lithium-ion batteries and enclosed in a weather-proof housing.
