This device is based on Red Seven Segment Displays at the size of 0.28 inch per digit. It operates from 2.6v to 30v (max) and has two leads both negative and positive, making this very simple to integrate to your circuit. You may need to calibrate the values on the back next to the 16 pin IC using a 1mm screw.

This Sensor Shield for Arduino Uno compatible microcontrollers makes interfacing with sensors and servos a breeze. All digital pins have been shifted inwards from where you would usually find them and next to the Digital Pins (S) are Gnd (G) and Vcc (V) bus. You can remove the jumper near the terminal block (SEL) and supply any fixed voltage from the terminal block you want for the entire Vcc bus or keep the jumper in place and offer 5v from Arduino 5V pin.
