Introduction
Outdoor PIR sensors face harsh conditions: rain, snow, temperature extremes, and direct sunlight. Choosing the right sensor requires considering weather resistance, detection range, and false alarm immunity.
Key Features for Outdoor Sensors
1. Weather Resistance (IP Rating)
- IP44: Splash-proof, suitable for covered porches
- IP55-IP65: Dust-protected, water jets, good for general outdoor use
- IP66-IP67: Powerful water jets or temporary immersion
2. Operating Temperature Range
- Standard range: -20°C to +60°C
- Wide range: -40°C to +85°C for extreme climates
3. Sunlight Rejection
Look for sun shields, optical filters, and sensors with good temperature compensation.
4. Range and Field of View
- Driveways: Long-range (15-30m) with narrow beam
- Patios: Wide-angle (90-120°) with medium range (8-15m)
- Perimeter security: Long-range curtain sensors (20-40m)

- Test range and coverage before final mounting
