Round Force-Sensitive Resistor (FSR)

Round Force-Sensitive Resistor (FSR)FSRs are sensors that allow you to detect physical pressure, squeezing and weight. They are simple to use and low cost. This sensor is a Interlink model 402 FSR with 1 2 diameter sensing region. FSR's are basically a resistor that changes its resistive value (in ohms ) depending on how much its pressed. These sensors are fairly low cost, and easy to use but they're rarely accurate. They also vary some from sensor to sensor perhaps 10%. So basically

you'll need to wick away that heat (otherwise the cold side will slowly get warmer)

Ripple voltage：<100mV @ 500mA

Make a GEMMA and NeoPixel Pixie Dust Bag

the sensor gathers small muscle signal then process with 2th amplify and filter

Dimensions (W x D): 110 x 118 mm / 4

Check the tutorial for details on how to do this

This is because the ground power wire is connected to the black current sense wire

This is the latest version

however it will keep your Pi B+ safe and svelte

due to Ampere's law(see drawing below)
