I'm building a wireless IR sensor for a alarm to let me know when granny's on the loose at night. I wanted to use a 4 channel push button remote and receiver that i had.
I hooked the receiver to a 8 pin picaxe and coded the alarm side. Thats working great, if you push the button on the remote the receiver sets the alarm perfect. the issue im having is with the transmitter side. Im useing a RHH HC-SR501 Adjust IR Pyroelectric Infrared PIR Motion Sensor.View attachment 17292 Thats working great to. the issue is the IR has a +3.3v output pin. I cant figure out how trigger one button on the remote with the 3.3v output of the IR. even if i added a picaxe on the transmitter side to use the 3.3v and switch something else. that's still wont help. I added the schematic of the transmitter chip and the buttons look like there in a resistor bridge of some sort. really not sure how to trigger it. All i need is a 1 sec pulse from the IR the set off the alarm. anyone have any thoughts?
