✨ LD2411 Human Distance & Gesture Module
-
👋 Detects gesture lifting & releasing movements
-
🚶 Recognizes approach & departure from the toilet
-
⚡ Outputs GPIO signals to let the microcontroller control toilet lid opening/closing
🔋 Power Supply: 5V 📡 Radar Beam Design:
-
Horizontal angle (4‑patch) ≈ ±20°
-
Vertical angle ≈ ±40°
-
Antenna direction can be adjusted depending on scenario
🚽 Toilet Application Tip:
-
Use a narrow horizontal beam ➡️ avoids false triggering when people walk by
