Hello.

  • In today's video we will do just such an alarm about the water leakage.
  • That will alert you with an audible signal Itself will block the water and call you on the phone.
  • You can also manually control the valves.

The scheme is simple and without AVR end Arduino

Detailed assembly and demonstration work can be seen on the video.

Step 1: We Need

  • One or two valves (valve with three terminals)
  • Old phone (I Siemens CX75)
  • A transistor IRLB8721
  • Resistor 2M
  • Relay 5 volts ( TRSB- 5VDC-SB-L15 or BT-5S 5V )
  • Buzzer HCM1206X
  • Diode SF18 or HER107 or FR104
  • Two buttons
  • Suitable housing
  • Four batteries

The scheme is very simple

Step 2: The Scheme Is Very Simple

Step 3: Attach the Scheme.

Step 4: Insert the Wires Into the Body

Step 5: Glue and Solder

Step 6: On Your Phone, Set Up a Quick Call to Your Number on the Button 9

Step 7: Phone Upgrade

  • remove the keyboard
  • disassemble
  • cut away the film on button 9
  • solder wire
  • cut off button 9
  • install the keyboard back

Step 8: Testing

Contact Sensor must be placed on the floor in the bathroom or in the kitchen.

The scheme is simple and without AVR end Arduino

Detailed assembly and demonstration work can be seen on the video.

Thank you for attention.
