DO203 Parking Occupation Sensor with Vehicle ID
DO203 Smart Parking Occupation Sensor with Vehicle Identification
24GHz Radar + Magnetic Detection + Bluetooth BLE Vehicle Beacon Reader
DO203 is a smart parking occupation sensor for outdoor parking detection and vehicle identity recognition. It uses 24GHz microwave radar and magnetic detection for up to 99% parking occupancy accuracy. When parking status changes, the built-in Bluetooth BLE beacon reader wakes up and scans nearby vehicle beacons, uploading up to 3 selected beacon records to the platform for vehicle identity judgement. IP68 waterproof, surface-mounted, with LoRaWAN, 4G, Cat-M+NB-IoT, and NB-IoT wireless options.

Detection and Identification
How DO203 detects occupancy and identifies vehicles
DO203 combines dual-sensor parking detection with Bluetooth beacon-based vehicle identity recognition to provide richer parking event data for billing, enforcement, and operations.
Occupancy Detection
24GHz microwave radar and magnetic detection work together to determine parking space occupancy with up to 99% accuracy. The dual-sensor approach improves reliability and reduces false triggers in outdoor environments.
Vehicle Identification
When parking status changes, the built-in Bluetooth beacon reader wakes up and scans for nearby vehicle beacons for 30 seconds. The sensor filters and ranks detected beacons by RSSI and detection count, uploading up to 3 selected records for platform-side identity judgement.

FAQ
Frequently Asked Questions about DO203
What makes DO203 different from DO202?
DO203 adds a built-in Bluetooth BLE beacon reader for vehicle identity recognition. When parking status changes, it scans nearby vehicle beacons and uploads up to 3 selected beacon records to the platform. DO202 detects parking occupancy only.
How does Bluetooth vehicle identification work?
A Bluetooth vehicle beacon (optional) is installed in the vehicle. On parking status change, the DO203 beacon reader wakes up and scans for 30 seconds. It filters detected beacons by RSSI and detection count, uploading up to 3 records for platform-side identity judgement.
Is the vehicle beacon included?
No. The Bluetooth vehicle beacon is an optional accessory sold separately. DO203 contains a beacon reader chip, not a beacon itself.
What parking layouts work best?
Vehicle recognition is more suitable for roadside spaces arranged front-to-back. Side-by-side spaces may have reduced performance due to beacon signal overlap. Detailed accuracy data pending further evaluation.
How long does the battery last?
Approximately 3.5 years under typical conditions (16 parking events/day, 10-minute detection cycle) using three ER26500 batteries with 25500 mAh total capacity.
What wireless versions are available?
LoRaWAN (multi-band), 4G (Asia/Europe/North America), Cat-M+NB-IoT, and NB-IoT. Final configuration depends on target region and selected module.
How is DO203 configured?
Via Bluetooth using a mobile phone app or PC app. Parameters include detection settings, beacon scanning duration, and wireless communication configuration.
Is DO203 a standard product?
Yes. DO203 is sold by quotation. Bluetooth vehicle beacons are optional accessories ordered separately. Share parking layout, network preference, and project scale for a quotation.
