Gsm motor starter circuit diagram. A wiring diagram is a streamlined conventional photographic representation of an electrical circuit. Your motor starter may use wiring which is internal to the starter wiring which is different than the diagrams etc. If you are not sure of how to make the connections on your equipment hire an electrician. All diagrams are intended to illustrate the logic of a latching contol circuit. The gsm based motor control circuit consists of a gsm modem for sending and receiving sms an arduino board will interpret the received sms command and gives out control signal to l298n dc motor driver which drives the motor at the desired speed and direction. 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.
Wiring diagrams do not show the operating mechanism since it is not electrically controlled. The other three are no normally open nc normally closed and com common. Assortment of 3 phase motor starter wiring diagram pdf. The above shown diagram is of a spdt single pole double throw relay. Other devices for disconnecting and short circuit protection may be needed typically a circuit breaker or fuses. The rx of gsm is connected to tx of arduino and tx of gsm is connected to rx of arduino.
It shows the parts of the circuit as simplified shapes and also the power and also signal links in between the tools. Lever mounted on the front of the switch. If you are confused just look at the below diagram misconnection will not send or receive sms. Two of them are from the coil where the input to drive the relay is supposed to be given. It consists of 5 terminals. Controlling motor with a cell phone circuit diagram explained gsm based cell phone remote control switch circuit electronic cheap cellphone controlled water pump circuit for farmers 3 phase motor starter automatic mobile starter mobile starter gsm based remote motor controller and status.
Gsm pump controller mobile motor starter. The motor starter must have at least two components to operate. A fixed 12v voltage regulator gives power to arduino gsm modem and relay. Circuit diagram showing nc connection of spdt relay. The circuit can be modified in many different ways as per the users specifications. These motor starters consist of an on off snap switch combined with a thermal overload device operating on the eutectic alloy ratchet principle.
The gsm modem is connected to arduino at pin 0 and pin 1 which are rx and tx respectively. In gsm based the gsm pump controllers mobile pump starter are specifically design to operate remote located submersible pumps and motors for benefit of farmers agriculture people and industries where wireless pump and motor control required.
