## Description

Great for approximating how much pressure is being exerted an FSR is a very versatile sensor.

Use the pressure-resistance relationship in a voltage divider to sense the amount of pressure being exerted, and use an ADC to grab the value.

When no pressure is being applied the resistance is well over 1M ohm.

### Specifications

- Sensing area: 0.7mm (0.02")
- Pin pitch: 2.54mm (0.1")
- Sensing range: 100g-10kg

### Examples

#### Raspberry Pi Pico - Micropython

 ```
import machine
import utime

# Additional hardware
# * 1x 10k resistor

fsr = machine.ADC(28)

# A handy function for mapping values
def map_range(x, in_min, in_max, out_min, out_max):
    mapped = (x - in_min) * (out_max - out_min) / (in_max - in_min) + out_min
    return int(max(min(mapped, out_max), out_min))

while True:
    fsr_raw_reading = fsr.read_u16()

    fsr_filtered_reading = map_range(fsr_raw_reading, 1000, 9000, 0, 100)
    print(fsr_filtered_reading)
    utime.sleep(0.5)
```
