Car Burglar Alarm
employs battery voltage detection
This time, Velleman have sent us a car burglar alarm construction kit for evaluation. This is a fairly simple but highly functional circuit, which is also offered at a very reasonable price.We don’t know Velleman’s sales figures, but we know from our own experience that burglar alarms — and in particular car burglar alarms — are almost without exception guaranteed success numbers. This is due not so much to the quality or originality of whatever circuit may be used, but simply to the intended use of the circuit. Burglary has always been a serious problem, but a steadily rising level of criminal activity has unfortunately made good protection of valuable goods more and more of a bitter necessity.
