800mm Resistive Film Pressure Sensor FSR 20g-10kg

Description

What it is

The 800 mm Resistive Film Pressure Sensor is an electronic component that measures the pressure applied to it. Based on FSR (Force Sensitive Resistor) technology, it varies its electrical resistance according to the force applied.

Features

• Name: 800 mm Resistive Film Pressure Sensor
• Type: FSR (Force Sensitive Resistor)
• Measurement Range: 20g – 10kg
• Dimensions: 800 mm (check datasheet)
• SKU: ARD0012387
• Price: 24.61 €

What it is for

This sensor is ideal for projects requiring pressure measurement, such as: bed exit alarms, smart cushions, pillow pads, flexible force-sensitive sofas. It can be used with microcontrollers like Arduino or ESP to process pressure data and trigger actions or signals based on measurements.

Tutorial: How to Use FSR 20g-10kg Pressure Sensor

The Force Sensitive Resistor (FSR) pressure sensor from 20g to 10kg is perfect for physical interaction projects. It converts mechanical pressure into a variable resistance that you can measure with an Arduino or another microcontroller.

What you need

• Arduino Uno
• USB cable
• LCD or LED
• Jumpers
• Breadboard
• Arduino IDE software

Steps

1. Connect the FSR sensor to the breadboard.
2. Connect a pull-down resistor to the FSR sensor.
3. Connect the FSR sensor to an analog pin on the Arduino.
4. Download and install the LiquidCrystal library for the LCD (if used).
5. Write and upload the Arduino sketch to read the sensor values.
6. Display the sensor values on an LCD or LED.
7. Check that the sensor correctly detects pressure.
8. Modify the sketch to fit your project.

Example code

void setup() {
  Serial.begin(9600);
}

void loop() {
  int sensorValue = analogRead(A0);
  Serial.println(sensorValue);
}

Mini project

Create a pressure-sensitive anti-theft alarm. Connect the FSR sensor to an alarm system that triggers an audio signal when pressed.

Common mistakes

• Use a pull-up resistor instead of a pull-down resistor.
• Do not connect the sensor correctly to the analog pins.
• Do not install the necessary library for the LCD.
• Do not continuously check the sensor values.

Recommended accessories

• LCD 16×2
• Buzzer
• 10kΩ pull-down resistor
• Jumpers
• Breadboard
