Sensor-Based PWAS System for Heavy Vehicles
Reliable Short-Range Proximity Detection for Safer Worksites
Shield Sensor’s Sensor-Based Proximity Warning & Alert System (PWAS) provides accurate, real-time detection of people and objects around heavy vehicles using advanced sensor technology.
Designed for Saudi Arabia’s construction, industrial, logistics, and oil & gas environments, this system delivers instant visual and audible alerts to help operators react before incidents occur.
- Cost-effective PWAS solution
- Ideal for blind-spot risk zones
- Suitable for harsh Saudi work conditions
What Is a Sensor-Based Proximity Warning & Alert System?
A Sensor-Based PWAS System is a proximity safety solution that uses microwave, ultrasonic, or similar industrial sensors to detect pedestrians, vehicles, or obstacles within predefined danger zones around equipment.
When movement is detected, the system immediately triggers:
- Audible alarms
- Visual in-cab alerts
This allows operators to take corrective action before a collision occurs.
When Is Sensor-Based PWAS the Right Choice?
Sensor-based systems are ideal when:
- Vehicles operate at low to medium speeds
- Blind-spot incidents are a primary risk
- The environment is structured and predictable
- A cost-effective safety upgrade is required
- Simple, reliable detection is preferred over AI vision
This makes Sensor-Based PWAS widely used across Saudi worksites.
How Shield Sensor’s Sensor-Based PWAS Works?
1. Zone Monitoring
Sensors are mounted around the vehicle to monitor defined proximity zones.
2. Object Detection
The system detects pedestrians, equipment, or obstacles entering the detection range.
3. Instant Alerts
Visual indicators and audible alarms warn the operator immediately.
4. Preventive Action
Early alerts give operators critical reaction time to stop or maneuver safely.
Key Features of Sensor-Based PWAS
- Pedestrian Detection: Detects personnel entering risk zones around vehicles.
- Blind Spot Coverage: Eliminates areas not visible to mirrors or cameras.
- Custom Detection Zones: Adjustable detection range based on vehicle size and site conditions.
- 360° Vehicle Coverage: Sensors can be placed around the entire vehicle.
- Reliable Detection: Consistent performance regardless of lighting conditions.
- Fast Response Time Immediate alert activation upon detection.
- Low Maintenance Design Industrial-grade sensors suitable for continuous operation.
How Sensor-Based PWAS Compares?
| Feature | Sensor-Based PWAS |
|---|---|
| Detection Method | Microwave / Ultrasonic Sensors |
| Human Identification | Presence-based |
| Light Dependency | Not affected |
| Dust / Fog Performance | Good |
| Cost Efficiency | High |
| False Alert Control | Zone-based |
Can be combined with AI or Radar PWAS for enhanced detection when required.
