Great value for learning
Excellent module for understanding pressure sensing. It took a little calibration to get steady readings, but once set up, it responds well to touch and weight changes.

Sensitive and durable
I've been using this for a digital scale prototype. The sensitivity is impressive for the price point. The thin film feels sturdy enough for repeated testing.

Good integration with IDE
The analog output is very linear within the mid-range. You need to write your own mapping code for specific weight units, but the hardware does its job perfectly.

Perfect for robotics grippers
This sensor works flawlessly with my Arduino Uno project. The resistance-to-voltage conversion is smooth, and the flexible film makes it easy to mount on curved surfaces of my robot hand.

Compact and effective
Small footprint makes it ideal for wearable tech projects. I attached it to a shoe insole to track step pressure, and the data logs are consistent.

Needs careful wiring
The sensor works, but the connector pins are a bit fragile. Make sure you solder carefully or use a breadboard gently. Once connected, the performance is solid.
Q: Is there a library available for this specific model?
A: While there isn't a brand-specific library, it functions as a standard analog sensor. You can use basic analogRead() functions or generic force sensor libraries available in the Arduino IDE.
Q: What is the maximum weight this can accurately measure?
A: The sensor is optimized for low to medium force applications, typically up to 10kg. Beyond this range, the readings may saturate or become non-linear.
Q: Does this module come with the connecting wires?
A: Yes, the package includes a short FPC cable to connect the sensor film to the breakout board module.
Q: Can this sensor measure dynamic force like tapping?
A: Absolutely. The piezoresistive element reacts quickly to changes in pressure, making it suitable for detecting taps or sudden impacts.
Q: Can I cut the flexible film to make it smaller?
A: No, cutting the active area of the thin film will damage the conductive traces and render the sensor non-functional. Please use the sensor as provided.
