Story

It system fully based on the security purpose which is use in INDUSTRY, FURNACE, HOME, MUSEUM and CAR security.

We have use three type of sensor in this system like

1-PIR (MOTION Sensor) it has detect the motion and theft within 10ft to 15ft.

2-SMOKE sensor:- it has sense the smoke and LPG(Liquid Petroleum Gas) and close the AC Appliance with relay;

3:-TEMP & HUM. sensor :- It has used to detect the temperature and humidity and this temperature range could be set by the USER via PRESET(VAR. RESISTANCE).

4.High Voltage Breaker(Above 245 AC Volt)

APPLICATION

1:-Reduce energy consumption by the AC(Air CONDITION).

2:-Used for home security.

3:-INDUSTRY

4:-Hospital etc.

No need of separate sensor for particular purpose security.

The TOTAL COST OF SYSTEM 2000(rupess) and 32(dollar) approximate
