The Cobra Line Follower Array provides 4 X QRE1113 IR reflectance sensor mounted on a 9mm pitch Each sensor is comprised of two parts - an IR emitting LED and an IR sensitive phototransistor. When you apply power to the VCC and GND pins the IR LED inside the sensor will illuminate.
The Danger Shield is an add-on for the [Arduino] micro controller board. It contains a variety of fun and useful electronic circuits that you can use to do fun and useful things. It is a fully self-contained shield. You plug it into your Arduino, and you can immediately start using it. No extra things to hook up, no external components. Just a really rad board ready to rock.
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.

“Generation 2” navX2-MXP is a drop-in replacement for “Classic” navX-MXP, adding significant performance enhancements. See the Frequently Asked Questions (FAQ) for more information about navX2-MXP's new and enhanced capabilities.
The Digilent PmodALS demonstrates light-to-digital sensing through a single ambient light sensor. Digilent Engineers designed this Pmod around Texas Instrument's ADC081S021 analog-to-digital converter and Vishay Semiconductor's TEMT6000X01.
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.
