Cheaters beware! A US-based company has developed a portable cellphone detector that vibrates and lights up each time there is a nearby transmission from a mobile phone, making it possible for teachers to catch a cheating student.

The gadget called Pocket Hound works by lighting up if there is a mobile phone transmission - a sign a cheater could be in action.

Once the device is set off, teachers can nab the offender, manufacturers said. The device has a battery life of about two hours and features an integrated multiband antenna that is hidden under the label, 'Business News Daily' reported.

The receiver continually scans all cellphone bands and utilises a sophisticated algorithm that constantly samples the radio-frequency (RF) noise floor to distinguish real cellular activity from ambient RF noise. The gadget has been developed by Berkeley Varitronics Systems and costs USD 500.

    Modern technology has made our life better and more convenient, but it also exert some bad effects on our life, cell phone is a case in point. As people depend on cell phones more and more, we can’t ignore the trouble they brings. In places where cell phones are not allowed to use, it is really difficult to find out who are using cell phones. Don’t worry, cell phone detector will solve your puzzle. This is very helpful so students be careful :(
