Wireless Strain Gauge Module for Remote Applications
Solution for Ultra Low Power Wireless Strain Monitoring
The wireless strain gauge module measures strain using a foil gauge. The gauge is attached to the bottom side of the printed circuit board, forms one side of the Wheatstone bridge, and changes in resistance when tension or compression are applied. The change in resistance causes a change in voltage across the Wheatstone bridge, which is amplified by the ISL28133 op amp in a differential configuration. The change in voltage is dependent on the flexibility of the surface to which the sensor is mounted. To conserve power, the voltage across the bridge is controlled by the ISL54051 low resistance switch and is turned on only when actively taking measurements. If higher resolution is required an ISL2671286 analog to digital converter can be added to the circuit.
