Sentry2 is a vision sensor which is designed by K210 – an advanced 64-bits RISC-V neural network processor. This device integrates a variety of advanced vision algorithms, which can meet the basic vision processing needs. The on-board ESP8285-WiFi chip can be programmed in Arduino IDE to realize online-recognition, image transmission, AIoT and other applications. ESP8285 can be used as a controller for K210 which is help for AI programming without external controller.
We offer 2 editions: Enterprise Edition (marked E) and Consumer Edition (marked C).
Applications: Robots, Smart Cars, Creative Design, STEAM Education, Maker, Toys, AIoT
Sentry2 can be connected to a controller via the output port, or connect to computer by a USB cable. The output port can be set as UART mode or I2C mode, device address and baudrate can also be modified.
CAUTION：USB and Communication Port can NOT be powered at the same time
The Sentry1 visual sensor adopts a dual core 240MHz-ESP32 processor, which can meet entry-level visual processing needs and is suitable for teaching young people and creating works.
Application fields: intelligent robots, intelligent cars, maker works, STEAM education, intelligent toys
LED light: Different colors of the light can reflect different recognition results, and can be used as a fill light when set to white light
Camera: Real time collection of image data
ESP32 processor: dual core 240MHz processor
USB: On board USB-UART chip, which can directly communicate and control with the computer, and serves as a firmware update interface. (Note: USB power supply will be output through the communication interface, and both cannot be powered at the same time)
Mode button: Short press to switch algorithm, long press to switch communication mode
Reset button: can achieve hardware reset, used in special circumstances
Communication interface: The interface between image processing data and the main control, supporting UART and I2C modes
The Sentry1 visual sensor can be connected to the main controller through a communication interface or to a computer through USB.
CAUTION：USB and Communication Port can NOT be powered at the same time !!!
