+# DO201 - Parking Occupancy Sensor
+
+The CNDingtek DO201 is a smart parking occupancy sensor with combination of ultrasonic and magnetic detection, temperature and humidity measurement. Designed for accurate vehicle detection in parking spaces, it provides 99% detection accuracy with IP68/IK10 enclosure rating, making it suitable for harsh outdoor environments.
+
+## Features
+
+- **Dual Detection Technology**: Ultrasonic and magnetic sensors for reliable vehicle presence detection
+- **Environmental Monitoring**: Built-in temperature and humidity sensors
+- **High Accuracy**: 99% detection precision
+- **Robust Design**: IP68 waterproof and IK10 impact-resistant enclosure
+- **Long Battery Life**: 25500mAh battery capacity (ER26500×3, 3.6V)
+- **Low Power Consumption**: Energy-efficient design for extended operation
+- **Compact Form Factor**: 183mm diameter, 38mm height
+- **Wide Operating Temperature**: -20°C to 70°C
+- **LoRaWAN Connectivity**: Long-range wireless communication
+
+## Use Cases
+
+- Smart parking lot management
+- Urban parking space monitoring
+- Commercial parking facilities
+- Street parking detection
+- Real-time parking availability systems
+
+## Thinger.io Integration
+
+The DO201 parking sensor integrates with Thinger.io through LoRaWAN connectivity, enabling real-time monitoring of parking occupancy status, temperature, and humidity data.
+
+## Requirements
+
+A LoRaWAN server is required to communicate the CNDingtek DO201 into Thinger.io, some options are:
+
+- [The Things Stack](https://www.thethingsindustries.com/stack/)
+- [LORIOT](https://loriot.io/)
+- [ChirpStack](https://www.chirpstack.io/)
+
+Alongside, the corresponding plugin for the selected LoRaWAN server needs to be installed in your Thinger.io instance.
+
+## Get Started
+
+### Installation
+
+Look for the plugin in the [Thinger.io Plugin Store](https://marketplace.thinger.io/) and install it in your Thinger.io instance. Once the plugin is installed a new Product will be created for this device.
+
+### Configuration
+
+The Product is already preconfigured, check that the auto provision prefix matches the one selected in your LoRaWAN server plugin in Thinger.io, or change it to your desire.
+
+### Usage
+
+Start sending uplinks for autoprovisioning devices and buckets.
+This product also provides a predefined dashboard and downlinks.
+
