Simple Cell Phone Motor Starter Controller Circuit Diagram. Line diagrams also called schematic or elementary diagrams show the circuits which form the basic operation of the controller. If the volt ages are different it is called separate control.
The circuit can be modified in many different ways as per the users specifications. It uses two contactors two auxiliary contact blocks an overload relay a mechanical interlock two normally open start pushbuttons a normally closed stop pushbutton and a power supply with a fuse. By calling the cellphone attached to the controller the water pump can be directly activated.
In the schottky diode circuit the schottky diode is used to detect the cell phone signal as they have a unique property of being able to rectify low frequency signals with low noise rate.
The modem cell phone should be appropriately assigned with a particular continuous ringtone while the default ringtone should be assigned to empty tis will make the unit immune to unknown numbers or wrong numbers and the owner will be the sole controller of the attached circuit and the motors. 1 shows the block diagram of cellphone based water pump remote controller. Cellphone based water pump remote controller circuit. All other control and power connections have to be made by the installer.
