Great for learning embedded systems

Bought this for my university thesis. It works exactly as described. The only minor issue is that the cable isn't included, so make sure you have jumper wires ready.

Perfect for robotics grip feedback

I integrated this module into a robotic gripper project. The serial communication is stable and the voltage output scales linearly with applied force. Very easy to calibrate with an Arduino.

Good sensitivity, needs calibration

The sensor is quite sensitive and picks up light touches well. You do need to spend some time calibrating it for your specific weight range, but the documentation provided by Lingzhi helps.

Excellent value for money

Compared to other FSR modules I've bought, this one offers the best price-to-performance ratio. The PCB layout is clean and the soldering points are accessible.

Reliable data transmission

Used this to log pressure data over several days. The serial output remained consistent without drift. Great for long-term monitoring applications.

Robust build quality

The thin film element feels durable despite being flexible. I've subjected it to repeated pressing cycles and it hasn't lost accuracy. Highly recommended for industrial prototyping.

5 FAQ

Q: Is there a library available for Arduino?

A: We provide sample code in C++ for Arduino in the product documentation download section. It reads the analog voltage and converts it to force values.

Q: Does this module come with a USB cable to connect directly to a PC?

A: No, the module features a 4-pin header for serial communication. You will need a separate USB-to-TTL adapter to connect it to a host computer.

Q: What baud rate does the serial communication use?

A: The default baud rate is 9600 bps, but it can be configured to 115200 bps by modifying the firmware settings if you have the appropriate programmer.

Q: Can this be used underwater?

A: No, this module is not waterproof. The electronic components on the PCB are exposed and will be damaged by moisture. You would need to apply a conformal coating or enclosure for wet environments.

Q: What is the maximum pressure this sensor can withstand before damage?

A: While the measurable range is up to 10kg, the sensor can physically withstand slightly higher forces. However, exceeding 15kg repeatedly may reduce the lifespan of the thin film element.
