This wireless smart parking sensor integrates dual magnetometer chips, radar, and NB‑IoT signal strength for multi‑mode fusion detection. Designed for on‑street parking, campus lots, and smart city projects, it achieves an industry‑leading accuracy of ≥99.95%. With robust anti‑interference, automatic temperature compensation, and IP68‑grade water resistance (operates normally under <20 cm water), it suits harsh outdoor environments. Data is reported directly to the cloud via Cat.1 / NB‑IoT without any gateway – simplifying deployment and reducing total cost of ownership.
Key Advantages
Pinpoint Accuracy, Zero False Alarms
Multi‑sensor fusion : Dual magnetometers work with radar ranging and signal‑strength analysis to reliably determine vehicle entry/exit direction.
Certified immunity : Passes both power‑frequency magnetic field (GB/T17626.8‑2006) and electrostatic discharge (GB/T176262‑2018) tests with Class A rating – strong magnetic interference and water submersion do not affect detection.
Ultra‑Low Power, Maintenance‑Free Longevity
Dynamic low‑power coordination extends battery life to ≥3 years under normal use, and up to 5–7 years in optimal conditions.
A triple‑layer waterproof inner shell, combined with a dedicated tool, allows easy battery and component replacement – reducing long‑term operational costs.
Remote Intelligence for Effortless Operations
Remote monitoring & configuration : Real‑time visibility of voltage, temperature, and signal strength; remote parameter changes, time synchronisation, and device rebooting.
Adjustable heartbeat interval (1–240 min) to suit different platform refresh requirements.
Fast response : Vehicle entry/exit detection within ≤1.5 s, and data delivery to handheld terminals within ≤5 s.
Self‑Learning & Self‑Correction – No Accumulated Errors
The device autonomously completes initialisation and magnetic‑field adaptation, with built‑in temperature‑difference compensation.
Supports algorithm reset and state‑reversal commands for remote intervention; the algorithm also self‑corrects with each vehicle movement, so errors never accumulate.
