Student Projects & Assignments. it requires no power. If your sole interest is measuring the force against a fixed threshold, a resistive divider, with the load cell as one leg, will be adequate. Double the resistor size or even triple it, and you will find the device is much less sensitive. A wide variety of fsr sensors options are available to you, such as pressure sensor, position sensor, and temperature sensor. DIY Stompboxes » Building your own stompbox » Wow! That graph of a force-sensing resistor puts it right in the range to be a pot replacement.
