Mini Soft Pressure Matrix

$28.00

If you are looking to map pressure over a 1.25in area, this is the one. The Loomia Mini Soft Pressure Matrix has six leads, allowing you to map which point you are at in the 3x3 matrix. Each area has an analog readout that varies depending on the weight of the item on the pressure sensor. Generally, sensor values will read from 500K Ohms to 100 Ohms depending on the force put onto the sensor.

Loomia parts are designed to be easily soldered together, and work well with popular micro controllers like Arduino Nano and Teensy. The system revolves around Loomia's custom interconnect, which allows for a simple connection between buses. The interconnect can be soldered to headers for easy breadboarding. From fabric to wood, Loomia components can stick onto a range of materials, making your prototypes look clean and polished.

Note: There are a number of operating procedures to be aware of before using Loomia products. This includes directions to not wash or sew any of the parts. Make sure to check the Datasheet at www.loomia.com/resources to get more information on this component.
