Modifying delay on PIR sensor based on BISS0001

I need to decrease unusual radio signals from my PIR sensor with 433MHz radio module.

If I moving in the room it sends 3 "packets" every 6 seconds. I need something like 2 packets every 2 minutes.

I find scheme of similar device:

Change resistor R13 (between 3 and 4 pin of BISS0001) to 1M Ohm.This make ~120 sec delay for timer. But when timer is on BISS0001 sends high level to radio module. I don't need 120 sec of radio signal.

Then I try to put capacitor between BISS and radio chip.

Break circuit line from BISS0001 to radio module and put capacitor inline.

I find that 220uF is enough for sending two "packets" by radio module.

Line from BISS to radio module goes on back side of PCB.

You may break line on back side and solder wires for capacitor between line break.

Now device starts sending packets every ~120 seconds if it find movement.
