Deal Breakdown
Real-World Test: Motion Magic
I mounted the BT31C in my hallway to control LED lights. Its 360° PIR sensor caught every step within 7 meters, flipping lights on instantly—perfect for late-night walks. The adjustable delay (10 seconds to 7 minutes) let me set it to stay on just long enough, and the 3–2000 lux sensitivity meant it didn’t trigger in daylight, saving power.
At just 0.35 lbs and 3.94 x 3.94 x 1.18 inches, it’s discreet but mighty. Installation took some fiddling to align the sensor, but once set, it worked flawlessly with my LEDs. For ₹559, this deal (live now, April 12, 2025) is a steal—ends April 30, 2025, so move fast!
