EASY PLUG Super Starter Kit For Arduino Project 7: How to measure the outside force?

Posted by Fiona Su on

Overview
How to measure the outside force? Use a pressure sensor.
Component Required:

  • EASY plug control board*1
  • EASY plug thin-film pressure sensor *1
  • EASY plug LED Module *1
  • RJ11 cable*1
  • USB cable*1

Component Introduction:


EASY plug Thin-film Pressure Sensor
This EASY plug pressure sensor adopts the flexible Nano pressure-sensitive material with an ultra-thin film pad.
It has the functions of water-proof and pressure detection.
The force sensors are ultra-thin and flexible printed circuits, which can be easily integrated into force measurement applications.
The harder you press, the lower the sensor's resistance.
When the sensor detects the outside pressure, the resistance of sensor will make a change. So we can use the circuit to convert the pressure signal that senses pressure change into the corresponding electric signal output.
In this way, we can know the conditions of pressure changes by detecting the signal changes.
You can connect the sensor to EASY plug Control board for communication using only a RJ11 cable.

  • Working Voltage: DC 3.3V—5V
  • Range: 0-0.5KG
  • Thickness: <0.25mm
  • Response Point: <20g
  • Repeatability: <±5.8%(50% load)
  • Accuracy: ±2.5%(85% range interval)
  • Durability: >100 thousand times
  • Initial Resistance: >100MΩ (no load)
  • Response Time: <1ms
  • Recovery Time: <15ms
  • Working Temperature: -20℃ to 60℃

Connect It Up

After uploading the code, open the serial monitor, and set the baud rate to 9600.
When tightly press the sensor, you should see the value become larger. So the sensor works normally.
