I m looking for something very simple just that detect it i don t need weight or anything else.
Weight sensor pad arduino.
So my idea is to put a sensor in the table and it has to detect that there is an object there using its weight or pressure.
We will be using the hx711 adc converter board to amplify.
Picture 1 shows the connected and powered up project.
Grams kg or pounds.
Using a load cell or weight sensor you can add this capability to your arduino projects.
There is a truly endless amount of applications for pressure sensor pads ranging from an input mechanism in a human machine interface hmi a method to capture intruders in a force sensitive security system and beyond.
Also connect a simple push button for calibration.
If you open the serial terminal in the arduino ide or visuino and there is no weight on the load cell you will see.
Connect vcc and gnd supply from arduino power source pins.
Connect the load cell wires to the hx711 module based on their color.
Inside a pressure pad are two layers of foil separated by a layer of foam with holes in it.
Makerhawk digital load cell weight sensor hx711 ad converter breakout module 5kg portable electronic kitchen scale for arduino scale 4 7 out of 5 stars 17 12 99 12.
You have created your first digital scale with arduino and hx711 adc weight sensor module.
Diy project to measure the weight by interfacing load cell and hx711 weight sensor with arduino uno.
Then connect dat data pin to arduino analog pin a3 and connect clk clock pin to arduino analog pin a2.
Pressure pads are designed to detect when pressure is applied to an area and they come in a variety of quality and accuracy.
The simplest pressure pads are often the equivalent of big switches.
In this tutorial we will see how to connect calibrate and display the weight on a small oled display and by using a rotary encoder we will be able to change the units from.

Find here the complete project tutorial with circuit dia.
Consider the following as you plan.
I have seen things like load cell and hx711.
Is there anything else we i can use.
Grove hcho sensor.
Analog ph sensor meter kit.
The video shows the running project and the serial terminal as different weights are placed on the load cell.
