Reliable for prototyping

We used these in several student projects. They are robust, consistent, and the bending sensor sensitivity is excellent for small weight measurements.

5 FAQ

Q: What is the maximum voltage input tolerance?

A: The module operates safely between 3.3V and 5V. Please do not exceed 5.5V to avoid damaging the ADC chip.

Q: Is the source code for the included program available?

A: Yes, we provide a download link in the user manual for the calibration program and data libraries compatible with common IDEs.

Q: Is it compatible with Raspberry Pi?

A: Absolutely. You can connect it via the I2C interface or GPIO pins using Python libraries provided in our documentation.

Q: Can this measure dynamic force or only static weight?

A: It is primarily optimized for static weighing applications, but it can capture dynamic force changes within its sampling rate limits.

Q: Does this module come with the strain gauge sensor attached?

A: Yes, this is a finished product that includes the bending sensor module already integrated with the amplification circuit.
