Strain Gauge Array Measurement System
The strain gauge measurement system consists of 4 tuned 320 ohm or 720 ohm wheatstone bridge. The bridge output is passed through a zero – drift Instrumentation amplifier and sampled by a 24 bit ADC which can sample at 32KBPS. ESP32 WROVER module will co-ordinate all the activities of the system.
