Constant SR602 False Positives - Motion detected every ~10s in empty room - how to address?
I have an ESP32-WROOM and an ESP32-C3 I'm trying to set up with a thermometer (DS18B20), motion sensor (SR602), IR blaster (2 bulbs via N2222), and IR receiver (TSOP4838). The pictured WROOM has 3 bulbs but the C3 has 2; the sensors on both are otherwise equivalently wired. The IR bulbs are getting used for a few seconds a day, and they're not active while this issue is happening. The motion history screenshot is from an empty room.
Everything is working besides the Sr602. On both the WROOM and the C3, the Sr602 is CONSTANTLY flipping back and forth between motion on/off in empty rooms. I thought it might be due to 3.3v power, but I moved it to the 5v pin and it got worse if anything. I just want to be able to see if there is active motion in a room by glancing at my HA card.
Is it possible to make the SR602 work with an esp32 (wroom or c3)? I assume my issue is EM interference but I am fairly new to electronics and don't know how to address. Is the wire that connects SR602-out to the data pin the one that needs protecting (long red wire in my pic)? I am unclear on whether it's the other sensors or the esp32 itself causing the noise. I was planning to put the pictured one on a smaller BB but never made it past testing.
