This is a small Force Sensitive Resistor . It has an Active Detection Area of 0.16 "(4mm) in Diameter. This FSR from Interlink Electronics varies its Resistance depending on how much Pressure is being applied to the Detection Area. The stronger the Force, the lower the Resistance. When there is no Pressure Applied to the FSR, its Resistance will be greater than 1MΩ, with the Total Pressure applied to the Resistance it will be 2.5kΩ Two Pins extend from the Bottom of the Sensor, making it friendly to the Breadboard. are simple to set up and great for detecting pressure.

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.
