Our Product is keypad based security system. In this product user can set and change their own 4 digit password at any time. The unit is constructing in such away that it has 4x3 matrix keypad ,Different LED indications, 10 amps Relay output ,12 v buzzer, PIC Microcontroller , etc..,There are many applications like home security, Industrial security , Banks ,Hospitals ,Office ,schools, colleges, etc..,to use this machine as reliable one.Overview

Step By Step Procedure To Access The Product

Our Project is to make relay ON and OFF by setting the Password.Initially beep sound is ON for one second to intimate the power supply is in ON condition. User can set the password by pressing menu key (# key) and buzzer will ON for 2 second.At that time yellow led blinks and then yellow led is ON to intimate user is in password setting mode. User should enter 4 digit passwords only after yellow led blinking stop.User should press set key (* key) to set the password.At that time green led blinks and then green led is ON to intimate user is in Normal mode.User can type correct password to make relay ON after green led blinking stop. If once again user enter correct password then relay will be in OFF condition. If user entered wrong password then buzzer will ON for 2second and this process will continue from first.

Remote control using a cell phone from anywhere in the world!

The GSM-AUTO is a GSM remote control switch, it connects to the cell phone network and like a cell phone has its own cell phone number. The GSM-AUTO is activated by Sending SMS to its cell phone number, it will recognize an authorized telephone number calling it, reject the call without answering and switch on or off the device connected to it, because it rejects the call without answering there are no call costs incurred. It has 6 independent relay switches with normally open and normally closed switch contacts, these can be programmed to switch on and Off By Sending SMS R1 R2 R3. The relay switches can also be switched on or off by sending the GSM-AUTO a SMS text message command. It can report the relay status by sending back a text message.


Applications :

• Applications are endless and include the remote control of heating and air conditioning in holiday homes, lighting, engine pre-heaters, aviation engine heaters, irrigation systems, water well pumps, pumping stations, cabin heaters, power cycle and reboot of remote servers, routers and computers.
• Dual band based GSM Modem.
• Independent relays that can be programmed to switch on and OFF Using SMS.
• Two access modes are available, open access where the GSM-AUTO will respond to any incoming call, and secure access where it will only respond to programmed authorized telephone numbers.( Only 1 No ).
• The relays can be temporarily switched on and Off by sending the GSM-AUTO a text message command, a confirmation text will be returned when the relays turn on and off if required.
• 6 relay's with normally open (N.O) and normally closed (N.C) contacts, maximum switching capacity is 10 amps @ 230V ac per relay.

IR Remote control is a combination of infrared transmitter and infrared receiver contains 4 relays and 1 Fan with Speed Control Through TRIAC which can be controlled wirelessly. This makes the unit very easy to operate and integrate with existing systems. The remote control operate the corresponding relay on the receiver board, Relay contact can control any equipment in Latch Mode (Toggles on each key press). Each relay has indicator LED showing current status.

The transmitter uses a modulated 40 kHz carrier to transmit data about which button is pressed. This method is used in all IR remote controls. At the receiver end the IR receiver module extracts the data signal from the carrier. This active HIGH output is used to operate a relay via ULN2803 which is an octal transistor array. 

Special Feature - Memory backup :

Memory backup Saves Last Condition of Relays if Power has gone with FAN Speed also. Custom Build Remote Control with Sleek match.

Features :

• Transmitter operating range up to 10 Meters visible distance.
• Compact 3V Battery Operated Transmitter.
• Receiver Indicates output status by LED.
