The HC-SR501 Infrared PIR Motion Sensor Module auto-senses light in various applications (in house, basement, outdoor, warehouse, garage, etc,) for ventilator control, alarm, etc. Infrared technology (LHI778 probe design) high sensitivity & high reliability. ultra-low-voltage. widely used especially for battery-powered products. This HC-SR501 Infrared...
This RGB color sensor module is based on the TCS34725 sensor chip made by TAOS. The module is designed by Adafruit who Called it (the best color sensor in the market). This is much confirmed by our own testing and experiments in future Electronics Egypt lab.
This module is the 16 way GPIO expander for the I2C interface, and built with the MCP23017.MCP23017 has a high-speed I2C interface which supports the I2C frequency of 100KHz, 400KHz and 1.7MHz. The chip has 3 address pins, which can be set up for 8 different addresses. So 8 modules can be connected through two I2C buses to achieve up to 128 IO extensions.
