This AA boost module integrates with TI's TPS61032 auxiliary chip, which is capable of producing 5V 1A with input above 1.8V . The only difference between V1 and V2 is to change the output current from 2A to 1A.

Adafruit Small 1.2 8x8 LED Matrix w/I2C Backpack - Yellow-Green

Basic breakout board for the TEMT6000 Ambient Light Sensor.

The flame sensor can be used to detect fire or another wavelength in light from 760 nm - 1100 nm.

Analog Hydrogen Gas Sensor MQ8

ORP (Oxidation-Reduction Potential) is a measure of oxidation capacity and reduction of the aqueous solution. Unlike a pH measurement that follows a logarithmic curve and therefore requires more calibration adjustments, O RP follows a linear relationship and does not need any instrument adjustments as well as electrode maintenance. ORP is a reliable method of measuring water quality and provides the operator with a unique measurement value.

This sliding position sensor is based on sliding potentiometer position sensor and can be easily combined with the Arduino sensor/IO expansion board .

Bi-directional Logic Level Converter 4-channel by I2C BSS138

The SparkFun Current Sensor Breakout is a High Precision Card that uses the ACS723 for Moderate AC and DC Current Detection Applications. The ACS723 Sensor uses a Hall Effect Sensor to Emit a Voltage relative to the Current that flows through the IP + and IP- Pins on the Board. The advantage of using a Hall Effect Sensor, specifically, is that the Circuit Being Detected and the Sensor Reading Circuit are Electrically Isolated, which means that although your Arduino is Operating at 5V, the Detected Circuit may be Operating at Higher DC or AC voltages.

BTBee Pro is a Bluetooth serial port module that can be compatible with shields that have XBee socket.
