700mm Resistive Film Pressure Sensor Bed Exit Alarm Detection Smart Cushion Flexible Force Sensitive Mat FSR 20g-10kg

Description

What it is

The FSR pressure sensor 700 mm is a resistive device that detects the pressure applied to a surface. It is ideal for projects requiring pressure detection from 20 grams to 10 kg.

Features

• Size: 700 mm
• Pressure Detection: 20g-10kg
• Flexible and force sensitive
• Ideally suited for anti-theft alarm and smart cushion projects

What it is for

This sensor can be used to create anti-theft alarms that activate when someone sits on a cushion or carpet. Additionally, it is perfect for creating smart cushions and pressure-sensitive carpets. The sensor is compatible with Arduino and ESP for programming and implementing interactive projects.

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

The FSR 20g-10kg pressure sensor is ideal for projects requiring the detection of applied pressure on a surface, such as anti-theft alarms or smart cushions. This sensor is perfect for beginner and intermediate makers who want to create interactive projects.

What you need

• Arduino Uno
• Head connections
• 5V power supply
• LED

Steps

1. Connect the FSR sensor pins to the Arduino Uno:
2. Connect the ‘+’ pin of the sensor to 5V
3. Connect the ‘-‘ pin of the sensor to GND
4. Connect the ‘S’ pin of the sensor to a digital pin of the Arduino
5. Install the A0 library on Arduino IDE
6. Write the Arduino sketch to read the sensor values
7. Check the sensor values through the serial console
8. Modify the sketch to turn on an LED when the pressure exceeds a certain value

Example code

void setup() {
  Serial.begin(9600);
  pinMode(2, INPUT);
}

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

Mini project

Create a theft alarm that activates when someone sits on a cushion or rug. The project takes less than 30 minutes to complete.

Common mistakes

• Do not connect the sensor correctly
• Do not check the sensor values before writing the sketch
• Do not adjust the sensor activation threshold
• Do not test the project in real conditions

Recommended accessories

• Arduino Uno
• LED
• Resistor
• Head connections

Frequently asked questions

How can I calibrate the sensor?
Calibrate the sensor by measuring the reference values when there is no pressure and when the pressure is maximum.

The sensor responds slowly
Check the power supply voltage and the resistance between the sensor and the Arduino.
