Easily add face detection to your project with the Person Sensor module

Person Sensor

It’s now much easier to AI features to your project thanks to better tools, but as we’ve experienced when trying out Edge Impulse machine learning platform on the XIAO BLE Sense board, it still requires some effort and the learning curve may be higher than some expect. But for common tasks like face detection, there’s no reason for the solution to be hard-to-use or expensive, and Pete Warden (Useful Sensors) has designed the $10 Person Sensor fitted with a camera module pre-programmed with algorithms that detect nearby faces and reports the results over an I2C interface.   Person Sensor specifications: ASIC – Himax HX6537-A ultra-low-power AI accelerator @ 400 MHz with 2MB SRAM, 2MB flash Camera Image Sensor – 110 degrees FOV Image scan rate – 7Hz with no facial recognition Image scan rate – 5Hz with facial recognition active Host interface Qwiic connector for the I2C interface up to […]

Innodisk releases USB camera modules for AI applications

Innodisk, better known for its industrial storage solutions and embedded peripherals, has recently announced a shift towards the AI industry, and the first products for this market are three USB 2.0 camera modules with 1920×1080 resolution.

Allwinner V851S/V851SE low-cost camera SoC embeds 64MB DDR2, a 0.5 TOPS NPU

Allwinner V851S/V851SE is a single-core Arm Cortex-A7 SoC with a RISC-V core, an H.265/H.264 video encoder, and a 0.5 TOPS NPU designed for Smart IP cameras with support for features such as human detection and crossing alarms. Both processors ship with 64MB DDR2 memory, and feature USB, Ethernet, and SDIO interfaces, but the V851S is designed for systems with a display, while the V851SE targets traditional headless IP cameras. Both processors are pretty similar, but here are the key differences between Allwinner V851S: Networking – 10/100 Mbps Ethernet port with RMII interface GPIO – 6x ports (PA, PC, PD, PE, PF, PH) Display LCD Parallel RGB, Serial RGB, i8080, BT656 2-lane MIPI DSI SPI – 4x SPI and Allwinner V851SE: Networking – SIP 100 Mbps EPHY GPIO – 5x ports (PA, PC, PE, PF, PH) Display – Not supported SPI – 3x SPI That means the Allwinner V851S requires an […]
