Electrical
• 3.3 VDC input
• I2C Output (10k Baudrate)
• Interrupt driven event pin for motion detection
• Design optimized for maximum battery life
Design Considerations
• Mounting location: ceiling, wall, corner
• PIR requires use of Fresnel lens
• Enclosure must allow free air movement over sensors
• Use of light pipe recommended to avoid shadowing
