The Smart City Loop Detector is a purpose-built solution for modern urban infrastructure, combining RoHS compliance with seamless IoT connectivity to drive sustainable, data-driven traffic management. Designed to meet stringent environmental standards, this detector eliminates hazardous substances (e.g., lead, mercury) while delivering 12-24V DC/100-240V AC wide voltage compatibility for solar-powered grids and traditional systems alike. Its plug-and-play IoT integration supports MQTT, REST API, and Modbus protocols, enabling real-time data streaming to cloud platforms like AWS IoT or Azure for predictive traffic analytics. Engineered with adaptive sensitivity (0-F), it accurately detects vehicles from bicycles to electric buses (15–2000μH range), even in high-interference zones near 5G towers or EV charging stations. The IP65-rated housing ensures reliability in extreme urban environments (heavy rain, dust), while onboard diagnostics monitor coil health and power stability, sending automated alerts to city maintenance teams via SMS or email.

Tailored for smart city ecosystems, this detector excels in dynamic traffic scenarios. In congestion pricing zones, its IoT integration enables real-time fee adjustments based on traffic density, reducing urban gridlock by up to 30%. For smart parking networks, the detector syncs with mobile apps to guide drivers to vacant spots, slashing idle emissions. Municipalities benefit from its RoHS-compliant design, aligning with global sustainability goals like the EU Green Deal. In air quality monitoring corridors, paired with environmental sensors, it triggers traffic rerouting during pollution spikes. Unlike generic detectors, its edge computing capability processes data locally, reducing cloud latency by 50% for critical applications like emergency vehicle prioritization. Certified for CE, FCC, and RoHS, and backed by a 3-year warranty, this detector is the cornerstone of resilient, eco-conscious urban mobility—where reliability meets tomorrow’s connectivity.

Features

• 1. 15-2000 μh detection Range
  • The loop detector supports a wide detection range from 15 µH to 2000 µH, accommodating various loop sizes and configurations for versatile application in different traffic detection scenarios. The wide detection range enables our loop detector to detect all kinds of vehicles, motorcycles, cars, Ultra long truck, buses and so on.

• 2. Compact Side
  • The compact and well-engineered housing combines all industry requirements for features and functionality, allowing this detector to be incorporated into any existing traffic detection system.

• 3. LED Diagnostic Capabilities
  • Comprehensive diagnostics capabilities enable accurate diagnosis of loop and installation problems and shows through LED, ensuring optimal performance and reducing downtime.

• 4. Selectable Presence Time
  • The output of the presence relay can be selected to limit a detect output to a fixed time (greater than 30 minutes) while a vehicle remains on the loop, providing flexibility in traffic management.

• 5. Loop Presence Time
  • Interference between adjacent loop detectors can be identified through integral indication and eliminated by adjusting the frequency setting, ensuring reliable operation.

• 6. Two Separate Output Relays
  • Presence Relay A: Provides presence output and can be extended for 0, 2, 5, 8, 10, 15, 20, or 30 seconds, programmable with external 10-way DIP switches.
  • Pulse Relay B: Programmable with external 10-way DIP switches, it offers presence, pulse on entry, pulse on exit, or failed output, enhancing detection flexibility.

• 7. Automatic Sensitivity Boost (ASB)
  • This feature reliably detects large truck-trailer combinations and high-bed vehicles by automatically boosting the sensitivity to maximum upon vehicle detection, ensuring accurate identification.

• 8. Automatic Environment Drifting Compensation
  • Loop detectors (or other sensors) automatically adjust and calibrate themselves to changes in environmental conditions, maintaining detection accuracy and stability despite varying weather and environmental factors.

• 9. 10 Dip Switch
  • The dip swich design on the shell makes the setting of loop detector easier and clearer, which is very user-friendly for users. Users can set all the functions first and then install the loop detector.

• 10. Anti-crosstalk interference.
  • Through the dip Switch, the frequency of the loop detector can be adjusted to prevent crosstalk interference caused by the installation of two loop coils too close.
