This is a small force sensitive resistor. It has a 0.16" (4 mm) diameter active 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 1MΩ, with full pressure applied the resistance will be 2.5kΩ.
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.

Jargon buster
Plain-language definitions for the technical terms used above.
- FSR
- FSR usually means full-scale range, the total span between the lowest and highest value a converter can output or measure, so error figures quoted as a percentage of FSR depend on the selected range such as 2.5 V or 5 V. In other contexts FSR can instead mean a force-sensing resistor, a component whose resistance changes with applied pressure, so check which sense is meant.
