thanks! hmm but there's a relay in the circuit. is it a must to include a relay?
Probably a light or buzzer. Can i just remove both the transistors and relay, and replace it with a light or buzzer?
Those kind of light that is able to shine at a person from head to toe. And a buzzer loud enough to alert the neighbours.
Hey anyway, is this https://info.hobbyengineering.com/specs/DIY-k49.pdf possible to use as the receiver part?
Sorry i didnt explain it properly.
I'm doing a ultrasonic motion sensor circuit to detect burglars to be built outdoor. Let's say a person walk pass the sensor, the light will shine on him.
Haha i see. Thanks dude!
I'm using infrared sensor for another part of the circuit. So don't wanna duplicate another one.![]()
hi,I'm using the infrared sensor for the main door part. If a burglar enters by the door, the infrared sensor will detect him and hence, the buzzer will sound and will alert the police through wireless technology.
Haha okay. Am from Singapore.![]()
In the UK, IF they eventually arrived, they would say 'if he comes back call us again',,, thats what you call a real 'cop out!'![]()
