This is a force sensitive resistor with a square, 1.75×1.5″, sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1Mohm. This FSR can sense applied force anywhere in the range of 100g-10kg. Two pins extend from the bottom of the sensor with 0.1″ pitch making it bread board friendly.

These sensors are simple to set up and great for sensing pressure, but they aren t incredibly accurate. Use them to sense if it s being squeezed, but you may not want to use it as a scale.

The GP2Y0A21 Sharp distance sensor is a great way to add obstacle avoidance or motion sensing to your robot or any other project. With a detection range of 4 to 32 (10 cm to 80 cm) and an analog voltage indicating the distance, this sensor is very easy to use.
This carrier board is designed to work with any of the MQ-series gas sensors, simplifying the interface from 6 to 3 pins ground, power and analog voltage output that are broken out with a 0.1″ spacing, making the board compatible with 0.1″ headers and standard breadboards and perfboards. This board has two mounting holes and provides convenient pads for mounting the gas sensor s required sensitivity-setting resistor.
Add lots of touch sensors to your next microcontroller project with this easy-to-use 8-channel capacitive touch sensor breakout board, starring the CAP1188. This chip can handle up to 8 individual touch pads, and has a very nice feature that makes it stand out for us: it will light up the 8 onboard LEDs when the matching touch sensor fires to help you debug your sensor setup.
