infrared devices are widely used and often for remotely controlled devices . With this IR receiver, your Arduino project is now able to receive commands from any IR remote controller.

This compact carrier board makes it easy to integrate a Sharp GP2Y0A60SZLF analog distance sensor (not included) into your project by providing all of the required external components and a 0.1?-pitch, four-pin interface to the sensor. This version of the carrier board is configured for 3V mode.

The 5-Channel Infrared Detector Sensor Module is designed to optimize robotics and electronics projects.

The Si7021 is a low-cost, easy-to-use, highly accurate, digital humidity and temperature sensor. 

DHT22 is a digital capacitive humidity sensor and humidity module is one that contains the compound has been calibrated with digital signal output from the temperature and humidity sensors . < / p>

Color is a Light to Digital Color Converter with IR Filter. The TCS3472 Device provides a digital red, green, blue (RGB) return and sharp light detection values. An infrared blocking filter, integrated in the chip and located in the color-sensing photodiodes, minimizes the infrared spectral component of the received light and allows color measurements to be made accurately.

This unit communicates with the M5Core through the Grove (I2C) port. The address is 0x29.
