FSR400 YouTuber “Peterbiglab” wanted an input for his DIY color-changing lamp, but didn’t want to use buttons or even have it detect claps, so he decided to make it respond to touch. Because the sensor reacts to forces applied, it can be placed under a panel to detect a pressure change. Buyer Protection. When it is pressed against with maximum pressure, its resistance falls to near 200Ω, so most of the voltage falls across the 10KΩ resistor and not the FSR. If the reading is above a certain threshold, The more one presses, the more of those Active Element dots touch the semiconductor and that makes the resistance go down. Since the FSR is connected Conductive foam is what microcontrollers generally come packaged in. US $3.00.
