## Description

Thin Film Pressure Sensor Flex/Bend Sensor SF15-150 Resistance Type Thin Film Pressure Sensor Force Sensing Resistor Force Sensitive Resistor: desertcart.com: Industrial & Scientific

Review: Works Well - The unit I received measured 1130 ohms relaxed and 720 ohms flexed so that the end looped around to the base. Letting it go allows it to relax again and it goes back to 1130 ohms. I am operating it at 5056 mV and used the Excel Spreadsheet "What If Analysis" to calculate the best fixed resistor to be 933 ohms. Maybe an adjustable potentiometer would be ideal to get as much range out of as possible. Whether operating it at 5V or 3.3V 933 ohms should work well (give you best range of voltages from relaxed to fully-flexed of 567 mV). I am using this to sense the body/limb position of a Teddy Bear.
Review: Accurate analog values - I kinda threw mine around and the values changed very slightly but still accurate. Best attached upon purchase for high accuracy.

## Features

- DUAL WATER-PROOF: The force resistance sensor has Waterproof and pressure sensitive dual function, more convenient to use
- HIGHLY SENSITIVE DETECTION: Highly sensitive flexible nano-meter materials can realize highly sensitive detection of pressure
- EXTREME SPEED RESPONSE: The flexible sensor has the characteristics of flexible ultra-thin, and extreme speed response, etc.
- HIGH EFFICIENCY: The force sensing resistor is compact design, easy to carry and store, with high sensitivity and long service life
- WIDELY APPLICATION: The force sensing resistor has widely applications during daily life, such as off-bed monitoring, intelligent breathing belt, sleep monitoring, electronic shelf

### ⭐⭐⭐⭐⭐ Review
*by A***T on May 24, 2025*

It's worthwhile to test this with an Ohmmeter to check the minimum and maximum resistance.
