Force Sensor / Load Cell
A force sensor or load cell converts mechanical force into an electrical signal.
- Type: Strain gauge, piezoelectric, capacitive
- Output: mV/V (analog), digital (with amplifier)
- Wiring: 4-wire (excitation+, excitation−, signal+, signal−)
- Common Use: Weighing scales, industrial automation, robotics
- Interface: HX711 amplifier for microcontrollers (e.g., Arduino)
Note: Calibrate with known weights for accurate readings.
