Arduino Board

Arduino is an open-source project that created microcontroller-based kits for building digital devices and interactive objects that can sense and control physical devices. The project is based on microcontroller board designs, produced by several vendors, using various microcontrollers.

Solenoid Valve

A solenoid valve is an electromechanically operated valve. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports.

Water Level Sensor

Water-level indicator is used to indicate the level of water in over head tank, by using this we can avoid the overflow of water, and at any time we can know the level of water in tank, it has a simple circuit .

Water level sensor connected to arduino

Carbon dioxide Catridges

It stores and releases compressed carbon Dioxide on demand. CO2 cartridges are small metal containers, about the size of your thumb, that hold highly pressurized CO2 (carbon dioxide) gas.

Relay Switch

A relay is an electromagnetic switch operated by a relatively small electric current that can turn on or off a much larger electric current. The relay switch will be activated when the water sensor reaches a certain value. The relay switch, when activated, will supply power to the solenoid valve, opening the valve and allowing CO2 to fill the balloons. Three components of Relay switch are Common, Normally closed and Normally open. For this circuit, common will be connected to the ground and NO, normally open, will be connected to the solenoid, a 12V battery will be used to power the solenoid. NC, normally closed, will remain unplugged since Arduino will only activate relay if the water level is reached. A magnetic field is created when current is flown through the circuit which pulls the contact and changes its position, which enables the circuit.
