Grove - Infrared Reflective Sensor v1.2 can be used for detection of proximity and color of objects. The reflective photosensor - RPR-220 used in this module consists of an infrared light emitting diode and a high –sensitivity phototransistor. Light-colored objects directly in front of the sensor will reflect more infrared light as well as generate more current in the phototransistor than an object with dark-colored surfaces, this can be tell from a built-in indicator LED which will turn red with sufficient flow of current. Also, the intensity of the reflective light increases as the object getting closer. You can adjust the potential-meter on the back of the board if you want to detect a specific object (eg. Black line) at a certain distance.

3-Axis Compass module, a member of grove family uses I²C based Honeywell HMC5883L digital compass. This ASIC is equipped with high resolution HMC118X magneto-resistive sensors and a 12-bit ADC. It provides compass heading accuracy up to 1° to 2°. Signal conditioning like amplification, automatic degaussing strap drivers and offset cancellation are inbuilt. This grove module also includes a MIC5205-3.3 for power supply requirement. Hence user can connect any 3.3V to 6V DC power supply.

Grove - BLE (dual model) v1.0 uses CSR dual mode Bluetooth chip,with the ARM architecture single chip which supports AT instructions, Users can develop flexibly according to the serial baud rate, equipment name, pairing password.
