Selection Guide

How to Choose the Right DO201 Configuration

Selecting the right DO201 version depends on the parking layout, surface conditions, network coverage, reporting strategy, and platform integration requirements.

Installation planningSurface mounting with expansion screws. Install at 1/3 of the bay entrance (not center). Maintain more than 1 m from adjacent bays to avoid interference.
Network selectionChoose NB-IoT, LoRaWAN, or 4G according to operator coverage and customer infrastructure. 4G version supports global LTE frequency bands.
Detection environmentUltrasonic detection works best in open-air or covered parking. Confirm that extreme environmental conditions (flooding, heavy snow) are considered in the deployment plan.
Power planningBattery life depends on upload frequency, cycle detection interval, network type, and ambient temperature. Reference: 4+ years at 15 uploads/day with 30-min cycle.
Environmental dataDO201 includes temperature and humidity sensing. Confirm whether this data should feed into the parking management platform for operational insights.
Platform workflowConfirm integration with CNDINGTEK cloud, customer platforms, guidance screens, mobile apps, or third-party parking systems. SDK available in Python and JavaScript.

FAQ

Frequently Asked Questions about DO201 Smart Parking Occupancy Sensor

What detection technology does DO201 use?

DO201 combines ultrasonic range measurement and magnetic detection for redundant vehicle presence sensing, achieving 99% detection accuracy. The ultrasonic sensor has a detection range of 2 meters. Errors only occur in extreme environmental conditions such as flooding or thunderstorms.

Which wireless versions are available for DO201?

DO201 is available with NB-IoT, LoRaWAN, and 4G wireless versions. The 4G version supports LTE-TDD (B34/B38/B39/B40/B41) and LTE-FDD (B1/B3/B5/B7/B8/B20/B28) frequency bands for global deployment.

How long can the DO201 battery last?

DO201 uses three ER26500 non-rechargeable lithium thionyl chloride batteries with 25500 mAh at 3.6 V. Datasheet reference life exceeds 4 years at 15 uploads per day with 30-minute cycle detection. Actual life depends on ambient temperature, network type, and wireless signal strength.

What certifications does DO201 have?

DO201 has CE and RoHS certifications. The ABS+PC enclosure is rated IP68 for waterproof protection and IK10 for impact resistance, suitable for outdoor surface-mounted parking bay installation.

How is DO201 installed?

DO201 uses surface mounting with expansion screws. The sensor is placed on the parking bay surface at approximately 1/3 of the entrance/exit position (not the center). Maintain more than 1 m distance from adjacent parking spaces to avoid interference from neighboring vehicles.

Can DO201 measure temperature and humidity?

Yes. DO201 includes temperature measurement (-30°C to +85°C, ±0.3°C) and humidity measurement (0-90%, ±2% RH), providing environmental monitoring data alongside parking occupancy status.

Can DO201 data be used with customer platforms?

Yes. DO201 data can be used with CNDINGTEK cloud applications (dashboard monitoring, email/SMS notifications) or customer systems. CNDINGTEK provides TCP protocol documentation and SDK support in Python and JavaScript after order placement.

Is DO201 a standard product or a customized product?

DO201 is a normally sold product with standard versions supporting multiple wireless options. Pricing is quotation-based after project requirements are reviewed.
