Hi everyone,
I’m currently working on a project to create a wireless motion detector using a PIR sensor and an RF transmitter. Both circuits function perfectly when tested separately. However, when I connect them, I encounter strange behavior: the output from the BISS0001 (PIR IC) either stays high continuously or blinks erratically.
To clarify, the PIR sensor correctly produces a high output upon detecting motion, and the RF transmitter sends signals as expected when activated independently. The PIR circuit was implemented from the BISS0001 datasheet, and for the RF section, I used an RF remote control board. I traced the connections using a multimeter and designed the circuit on my board, replacing the push button with a transistor (Q4 from the schematic).
I would greatly appreciate any guidance on how to successfully integrate these two circuits. Your expertise would be invaluable in resolving this issue.
Thank you in advance for your help!
