GSM Alarm System for Leaks Without Arduino

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.

• 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

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

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

Thank you for attention.
