Switching cob leds

[danadak]

PIC is a Microchip Microprocessor. Probably used in sensor.

La2 the led strip ?

Hi Nigel;
I don't know what a PIC pin is or an La2.

As already mentioned, a PIC is a micro-controller, in your case the signal will come from the sensor - LA2 is the symbol for a bulb, in your case you would replace the bulb with the LED's.

I suspect the PIR module is a HC-SR501. I have ttached the data sheet for this module and the data sheet for the chip that it uses. I think the maximum output current is about 3 mA. It has a 1K resistor between the output pin on the chip and the output pin on the module.

This is the pir



The resistor on the out pin is a 102.

 

[Les Jones]

Yes 102 is 1K (10 x 10^2)

Want to report this will work with BD237 power transistor.
