Motion detection using Passive Infrared Sensor using IoT

Intrusion Detection in IOT based Networks Using Double Discriminant Analysis

Intrusion detection is one of the main challenges in wireless systems especially in Internet of things (IOT) based networks. There are various attack types such as probe, denial of service, remote to local and user to root. In addition to known attacks and malicious behaviors, there are various unknown attacks that some of them have similar behavior with respect to each other or mimic the norma...

Motion Detection using Device-free Passive Localisation (DfPL)

The holy grail of tracking people indoors is being able to locate them when they are not carrying any wireless tracking devices. The aim is to be able to track people just through their physical body interfering with a standard wireless network that would be in most peoples home. The human body contains about 70% water which attenuates the wireless signal reacting as an absorber. The changes in...

Passive infrared imaging sensor for standoff detection of methane leaks

Physical Sciences Inc. (PSI) has developed an imaging sensor for remote detection of natural gas (methane) leaks. The sensor is comprised of an IR focal plane array-based camera which views the far field through a rapidly tunable FabryPerot interferometer. The interferometer functions as a wavelength-variable bandpass filter which selects the wavelength illuminating the focal plane array. The s...

Crack Detection Using a Passive Wireless Strain Sensor

Passive Infrared (PIR) Sensor Based Security Control System using Microcontroller using 89C51

-This paper evaluate the development of low cost security system in the area where there is need of continuous monitoring using PIR (pyroelectric infrared) sensor. A special type of human sensor PIR is used to detect the human being around 20 feet distance. This sensor uses the concept of Black Body Radiation. If anyone tries to cross the area means the sensor detects and it sends a signal to t...
