Frequently Asked Questions

What is the output signal of this force sensor and how do I interface it with a microcontroller?

The sensor provides a linear resistance output that varies with applied force. To interface it, connect the sensor in a voltage divider circuit with a fixed resistor, then read the resulting analog voltage with a microcontroller's ADC pin (e.g., on an Arduino or ESP32). The resistance ranges from less than 200 kΩ at 20g to under 1 kΩ at 6kg.

What is the maximum operating temperature and environment for this sensor?

This graphene-based sensor is rated for continuous operation from -40°C to +120°C. Its thin-film construction and high-temperature materials make it suitable for harsh environments, including inside automotive assemblies, industrial control panels, and near heat-generating components where traditional sensors might fail.

Can this sensor be soldered directly, and what are the electrical connection guidelines?

Yes, the sensor pads support direct soldering for a secure and vibration-resistant connection, which is more reliable than connector-based FSRs in dynamic applications. Use the recommended operating voltage of 2.7V to 5.5V. Ensure soldering is performed quickly to avoid excessive heat damage to the thin-film element.
