+# DC510 - People Counter
+
+The CNDingtek DC510 is a PIR-based people counter designed for indoor use to calculate the number of people entering or passing through a monitored area. This wireless sensor provides single-direction people flow counting without capturing images or video, ensuring privacy compliance while delivering accurate occupancy data for building management and crowd control applications.
+
+## Features
+
+- **PIR Sensor Technology**: Passive infrared detection for reliable people counting
+- **Single-Direction Counting**: Monitors unidirectional people flow
+- **Privacy-Focused Design**: No image or video capture
+- **LoRaWAN Connectivity**: Low-power wireless communication for long-range data transmission
+- **Multi-Protocol Support**: Available with LoRaWAN, NB-IoT, or Sigfox connectivity options
+- **IP65 Enclosure**: Dust-tight and water-resistant housing
+- **Compact Design**: 110 x 109 x 25 mm dimensions
+- **Wide Operating Temperature**: -20°C to 70°C
+- **Battery Powered**: Long-lasting operation (up to 1 year typical battery life)
+
+## Use Cases
+
+- Conference rooms and meeting spaces
+- Hotels and hospitality venues
+- Parks and public spaces
+- Factories and industrial facilities
+- Retail stores and shopping centers
+- Building occupancy monitoring
+- Crowd control and flow management
+- Capacity limit monitoring and alerts
+
+## Thinger.io Integration
+
+The DC510 people counter can be integrated with Thinger.io through a LoRaWAN network server, enabling real-time monitoring of occupancy data, historical trend analysis, and automated alerting based on people count thresholds.
+
+## Requirements
+
+A LoRaWAN server is required to communicate the CNDingtek DC510 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.
+
