Abstract
In present day’s security from unauthorized humans (intruders) and fire/flame is one of the essential concerns especially in industries, banks, airports, railway stations and other restricted areas. Therefore, we introduce an Electronic Security System (ESS). The ESS provides the attentive message from flame as well as intruders. The proposed system generally consists of 3 devices namely PIR sensors, MSP430 and GSM. The flames and intruder are recognized by PIR. These activities are feeding to HMM, which are synthesized by wavelet transform. When there is an action occurs within the sensor range, then signal from sensor is processed by biorthogonal wavelet transform and then feeding to HMMs. The detection of intruder and flame is updated according to the HMM producing the highest probability. After that the alert message is sent to authorize person using GSM. Keywords: Electronic Security System, Wavelet, GSM, HMM, MSP430, PIR
Highlights
Unauthorized Humans and fire are the main concerns for safety issues in shopping malls, forest areas, bus stations etc
We are utilizing the IS9B PIR sensor with radius of 5m, this is sufficient to cover up the majority rooms with high ceilings
Power 1 (3v): It is given to MSP430 and PIR sensor module
Summary
Unauthorized Humans and fire are the main concerns for safety issues in shopping malls, forest areas, bus stations etc. To provide safety we introduce an Electronic Security System (ESS). Whenever a person walk across the device, IR is activated This device is efficient in detecting the intruders, but the response time to detect the fire is high. To conquer above problems/issues, we introduce PIR based ESS with high accuracy and low latency in detecting the flame and intruder. We are utilizing the IS9B PIR sensor with radius of 5m, this is sufficient to cover up the majority rooms with high ceilings. PIR based systems provide a cost-effective solution to recognize the unauthorized persons and fire issues especially in large rooms
