TDD1-PIR30 Lane Selective Detection of Approaching Vehicles Features • • • • The TDD1-PIR is an advanced traffic detector for detecting approaching vehicles at intersections. The detector utilizes a single, focused PIR detection zone to detect small temperature changes caused by passing vehicles. Passing vehicles cause the digital output to activate to announce their approach for traffic light controller to activate or extend green phase. The relay output returns to its original state and calls are not held when a vehicle comes to a stand-still inside the detection zone. The detection is dynamic only. Typical Applications ADEC TDD1-PIR detector is specifically designed for a variety of intersection applications, primarily approaching vehicle detection. Lane-selective detection of approaching vehicles at intersections Detection of approaching vehicles Precise, focused detection zone for laneselective vehicle detection applications Zero-configuration deployment Simple, quick, and cost-effective installation Dry-contact output SPDT relay output Environmental immunity Reliable detection of approaching vehicles in any environmental condition Flexible mounting range Detection of 30 meters Wide operating temperature range –40 to +70°C (–40 to +158ºF) Optimal performance in all weather and climate conditions Wide voltage range Accepts supply voltage from 9 to 40 V DC Low power consumption Consumes 260 mW max. (with activated relay output) Detection of vehicles entering or passing through small, focused detection zone Working principle The TDD1-PIR traffic detector employs a single, focused PIR detection zone. The detection zone’s opening angle is only 1.3°, corresponding to approximately 0.7 m at 30 m distance allowing for lane-specific alignment. The sensor element detects slightest changes in thermal infrared radiation, such as the difference in temperature of a passing vehicle from the road surface background temperature. Sudden temperature changes like that correspond to a passing vehicle, while gradual temperature changes such as caused by variations in the environmental conditions etc. are to slow to cause detection. Superior performance, environmental immunity and zero-configuration deployment are a result of: Dual channel opposite PIR sensor Full temperature compensation across entire temperature range µP-controlled signal processing Mounting Recommended mounting points are stable structures such as posts or beams for traffic light heads, streetlight poles etc. ADEC Technologies AG ● Gublenstrasse 1 ● CH-8733 Eschenbach SG● Switzerla
