Description: 1. Overview: A Strain Gauge Module is an essential IoT component used for measuring strain or force in various applications such as weight measurement, stress analysis, and structural health monitoring. 2. Construction: The module typically includes a strain gauge sensor, an amplifier circuit, and a bridge circuit configuration for converting mechanical strain into electrical resistance changes. 3. Strain Gauge Sensor: The heart of the system is the strain gauge sensor which generates a small electric signal when subjected to mechanical stress or strain. This signal is then amplified for further processing. 4. Bridge Circuit: The bridge circuit configuration is used to measure the resistance imbalance between the active and reference arms of the circuit. The signal obtained from the strain gauge sensor is introduced into one arm, causing an imbalance that generates an output voltage. 5. Amplifier Circuit: A built-in amplifier circuit enhances the weak output generated by the strai
