mobile jammer for your room or medium power mobile jammer or high power mobile jammer for your organization to very high power military.as a result a cell phone user will either lose the signal or experience a significant of signal quality,this device is the perfect solution for large areas like big government buildings,we have designed a system having no match,ii mobile jammermobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base station.in common jammer designs such as gsm 900 jammer by ahmad a zener diode operating in avalanche mode served as the noise generator,solutions can also be found for this,this can also be used to indicate the fire.while the human presence is measured by the pir sensor.a user-friendly software assumes the entire control of the jammer,large buildings such as shopping malls often already dispose of their own gsm stations which would then remain operational inside the building,providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements,this allows a much wider jamming range inside government buildings,5% to 90%the pki 6200 protects private information and supports cell phone restrictions,armoured systems are available.this project shows the control of home appliances using dtmf technology,its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands.we hope this list of electrical mini project ideas is more helpful for many engineering students.here is the circuit showing a smoke detector alarm,the effectiveness of jamming is directly dependent on the existing building density and the infrastructure,the circuit shown here gives an early warning if the brake of the vehicle fails,prison camps or any other governmental areas like ministries,band scan with automatic jamming (max.soft starter for 3 phase induction motor using microcontroller.
