Comparison
DO201 vs DO202 Parking Occupancy Sensors
Use this comparison to choose between DO201 (ultrasonic + magnetic) and DO202 (radar + magnetic) for your surface-mount parking project.
| Selection factor | DO201 Parking Occupancy Sensor | DO202 Parking Occupancy Sensor |
|---|---|---|
| Detection technology | Ultrasonic range + magnetic detection | 24GHz radar + magnetic detection |
| Detection accuracy | 99% | 99% |
| Ultrasonic/radar range | 2 m ultrasonic detection | Radar detection (surface-mount) |
| Battery | ER26500 x3, 25500 mAh at 3.6 V | ER26500 x3, 25500 mAh at 3.6 V |
| Battery life | More than 4 years at 15 uploads/day | More than 7 years under reference conditions |
| Protection | IP68 / IK10 | IP68 / IK10 |
| Wireless options | NB-IoT, LoRaWAN, 4G | 4G, LoRaWAN, NB-IoT, Multi Tech Cat-M/NB-IoT |
| Environmental sensing | Temperature + humidity | Temperature |
| Enclosure | ABS+PC, 183x183x38 mm | ABS+PC, surface-mount form |
| When to choose | Choose DO201 when ultrasonic-based detection fits the parking environment and temperature + humidity sensing adds operational value. | Choose DO202 when radar-based detection is preferred and maximum battery life (7+ years) is a priority for the parking project. |

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.
