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.
Bluetooth Based Dc Motor Speed And Direction Control Using
Gsm motor starter circuit diagram. Assortment of 3 phase motor starter wiring diagram pdf. The above shown diagram is of a spdt single pole double throw relay. 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 other three are no normally open nc normally closed and com common. A fixed 12v voltage regulator gives power to arduino gsm modem and relay. If you are not sure of how to make the connections on your equipment hire an electrician.
A contactor to open or close the flow of energy to the motor and an overload relay to protect the motor against thermal overload. 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. These motor starters consist of an on off snap switch combined with a thermal overload device operating on the eutectic alloy ratchet principle. 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. The circuit can be modified in many different ways as per the users specifications. It shows the parts of the circuit as simplified shapes and also the power and also signal links in between the tools.
Your motor starter may use wiring which is internal to the starter wiring which is different than the diagrams etc. The rx of gsm is connected to tx of arduino and tx of gsm is connected to rx of arduino. Other devices for disconnecting and short circuit protection may be needed typically a circuit breaker or fuses. The gsm modem is connected to arduino at pin 0 and pin 1 which are rx and tx respectively. All diagrams are intended to illustrate the logic of a latching contol circuit. Circuit diagram showing nc connection of spdt relay.
A wiring diagram is a streamlined conventional photographic representation of an electrical circuit. Wiring diagrams do not show the operating mechanism since it is not electrically controlled. 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. Please refer to the manufacturers literature if in doubt.
The motor starter must have at least two components to operate. Gsm pump controller mobile motor starter.
