Hi everyone,
I’ve set up two radar sensors — an LD2410 and an LD2450 — both connected to an ESP32-S3 using separate UART pins. They’re placed in the same enclosure, facing the same direction, but their detection zones do not physically overlap.
The issue:
When the LD2450 is active, the LD2410 starts reporting false positives, detecting motion even when there’s none. I’ve tested with:
• TX/RX lines completely disconnected,
• Power supplied from separate isolated sources,
• No shared wiring or ground loops.
My conclusion: this is RF (radio frequency) interference through the air. The LD2450’s signal appears to interfere with the LD2410’s sensing.
If anyone has run into similar interference and found a clean solution — I’d really appreciate your insights!
