Strain Gauge Bending Sensor Module Y3 BF350-3AA
The Strain Gauge Bending Sensor Module Y3 is a compact force, bending, strain, pressure, and weight sensing module designed for electronics projects, Arduino, robotics, IoT, laboratory experiments, and mechanical measurement applications. It uses a BF350-3AA strain gauge with an onboard signal amplification circuit to convert small mechanical deformation into a measurable analog voltage signal.
When the attached surface bends or experiences mechanical stress, the electrical resistance of the strain gauge changes. The Y3 module detects this resistance variation and produces an analog voltage output that can be read by a microcontroller ADC such as Arduino, ESP32, STM32, or other analog measurement systems.
An onboard zero adjustment potentiometer allows the starting output level to be calibrated. The module also includes reverse-polarity protection and a blue power indicator LED, making it convenient for student projects, prototypes, robotics experiments, weighing systems, and force measurement applications.
For Bangladeshi electronics students and engineers, the Y3 strain gauge module is useful for learning how strain gauges, Wheatstone bridge sensing, mechanical deformation, analog signal conditioning, and ADC measurement work in practical electronics projects.
