INTRODUCTION
The FSR-406 Square Force Sensitive Resistor (FSR) is a versatile and innovative sensor designed to detect and measure force or pressure applied to its surface. This thin, flexible device operates on the principle that its resistance decreases as the force applied increases, allowing for a wide range of applications in various fields, including robotics, consumer electronics, and interactive installations. With its square shape, the FSR-406 is particularly suited for applications requiring a larger sensing area, making it ideal for use in touch-sensitive interfaces, pressure-sensitive mats, and wearable technology. Its ease of integration with microcontrollers and other electronic components makes it a popular choice among hobbyists and professionals alike, enabling the development of responsive and interactive systems.
The FSR-406 is a type of force-sensitive resistor (FSR) that changes its resistance based on the amount of force or pressure applied to its surface. Here are the typical specifications for the FSR-406:
SPECIFICATION
1. Dimensions:
- Shape: Square
- Size: 4.0 cm x 4.0 cm (approximately)
2. Resistance:
- Unloaded Resistance: Typically ranges from 10 kΩ to 1 MΩ (depending on the force applied).
- Resistance decreases as force increases.
3. Force Range:
- Minimum Force: Approximately 0.1 N (grams)
- Maximum Force: Up to 10 N (grams)
4. Sensitivity:
- The sensitivity of the FSR can vary based on the application and the specific setup, but it is generally designed to detect light to moderate pressure.
5. Operating Temperature:
- Typically operates within a temperature range of -20°C to +70°C.
6. Material:
- The sensing element is made of a conductive polymer that changes resistance when pressure is applied.
7. Response Time:
- Fast response time, typically in the milliseconds range.
8. Hysteresis:
- Minimal hysteresis, allowing for consistent readings when pressure is applied and released.
9. Mounting:
- Can be easily mounted using adhesive or integrated into various applications.
Notes:
- The FSR-406 is a passive device, meaning it requires an external circuit to measure the change in resistance.
- Calibration may be necessary to achieve accurate readings based on the specific application.
