Product overview
This Whadda module uses a PIR (Pyroelectric InfraRed) motion sensor to detect infrared signals
from a moving person or moving animal. The module sends out a simple HIGH logic level signal for
2-3 seconds when it has detected motion.

Operating current: 15 μA
Output signal voltage: High 3 V, Low 0 V
Detection Angle: 100°
Detection Distance: 3-4 meters
Weight: 4 g
Dimensions (W x L x H): 34.4 x 20.0 x 12.5 mm
