Strain Gauge Sensor BF350-3AA

A resistive strain gauge sensor with a 350 ohm nominal resistance which varies when a force is applied. By measuring the change in the sensors resistance a measurement of the force applied to it can be obtained. Note that strain gauges exhibit small changes in resistance and so this sensor should be used in a Wheatstone bridge configuration. If using with a microcontroller such as an Arduino we also recommend using our HX711 digital bridge sensor interface module
