Detect mines and unexploded ammunitions.
Operating temperature : -30 degree to +55 degree .
Operating principle : Building up a magnetic field via electric pulse to produce secondary field which is picked by a receiver coil.
Harmonic Radar: Super Broom
Detects electronic components such as diodes, transistors, ICs etc.
Does not react to components that do not contain semiconductor materials.
Signal generated is pure radio
signal with a freq. of

Power Amplifier (A2)
Display Unit (A8)
This laser based perimeter protection system having -9 to +9 volt DC supply system.
Transmitter card consists-IC LM/NE 567,LF 356.
Receiver is tuned to the transmitter's frequency.
IC 567 is a CCO which generate a pulsed waveform of frequency 1 k Hz.
Value of frequency is set by (1.1/R1C1).
IC 356 & transistor (2N2222) is a output driver circuit.
It drive the laser diode with a pulse amplitude 3V.
When an intruder tries to cross the unauthorized Area or boundary, then the LASER link between the transmitter and receiver is broken.
When laser beam is interrupted, diode act as open circuit.
Thus o/p of NIV amplifier become Low.
The pin-8 of ic goes LOW and the alarm connected via Buzzer is switched ON.
So the protection system is fool-proof and highly reliable.
