Introduction: Multi Funcional Sensors Play Ground With Arduino

By Visit my blog!
About: My name is Simao and I love eletronics ,glass art,metal working,casting,paint ,draw... But above all... Trains

This is a multi-funcional project .

It can be mesure :distances,temperature in degrees Celcios,flame , light and tilt ,it is like a swiss knife ..no because it is eletroni and haven't knife ,how ever it is very use full very projects in just one .Amazing!!

Supplies

  1. HC-SR05(ultra-sonic sensor).
  2. Arduino UNO R3
  3. Piezo Buzzer.
  4. Flame Sensor
  5. tilt switch
  6. LDR
  7. LM35(temperature sensor)
  8. 10k potenciometer
  9. LCD 16x2
  10. Breadboard (large)

Step 1: Mode's:

You can change the mode when you want ,you just have to turn the potenciometer to chose the mode.

1st Mode:Distance meter:

In this mode you can mesure distances between 0cm and 1000cm(or 10 meters if you want ), in "cm"(centimeters)unit.

2nd Mode :Fire Alarm:

If you have something burns it produce a noise(200Hz and 400Hz).

3rd Mode:Tilt alarm:

the same thing that the name exposes.

4th Mode:Light meter:

This mode mesure the light in "%".

5th Mode:Thermometer :

This thermometer isn't very precised put give us a real approximated read.

Step 2: Wiring Sequence:

LCD:

* vss,GND * vdd,+5V * vo ,GND * rs,2 * rw,GND * e,3 * d4,4 * d5,5 * d6,6 * d7,7 * A,+5V * K,GND * ultra -sonic(HC-SR05): * vcc.+5V * echo,12 * trig,13 * output ,____ * GND,GND * BUZZER: * pin1,GND * pin2,9(PWM~) * potenciometer: * pin1,GND * Cursor,A4 * pin2,+5V * flame sensor * GND,GND * VCC,A3 * tilt swtch: * pin1,GND * pin2,A2 * LDR: * pin1,GND * pin2,A1 * LM35: * vcc,+5v * vood,A0 * GND,GND *

If you downlod this sketch to use ,download thi .ino version.

if you want this sketch to use some day that you don't no when , download the .zip file no1.

If you want to put this in a e-mail download .txt file.

if you want all these download fileNo2.zip that contains every thing.

Step 4: 2nd Revision.

I realise about some errors on the code and on the components .

Problems:

  1. HC-SR05 ultrasónic sensor is rare on the market
  2. The fire mode don't work very well.
  3. the temperature mode have bad mesures.

Solutions:

  1. Change the sensor to HC-SR04.
  2. Repair the fire mode.
  3. Repair the temperature mesure mode.

So ,I correct the code and change this one.

2nd Revision Code:
