dToF Laser Module
Overviewβ
The Polaris IC DTS6012M is a fully integrated single-channel direct Time-of-Flight (dToF) laser ranging mini-module with a built-in VCSEL laser and single-photon detector (SPAD), supporting both I2C and UART communication interfaces. With a wide measurement range of 0.2m to 20m, a maximum frame rate of 250fps, and Class 1 laser safety certification, it is suitable for smart access control, drone altitude holding, robot obstacle avoidance, and other applications.

1. Product Overviewβ
1.1 Key Featuresβ
- Fully integrated design: Built-in VCSEL laser + SPAD detector + signal processing circuit, no external optical components required
- High frame rate: Up to 250fps, meeting the needs of high-speed dynamic scenarios
- Wide measurement range: 0.2m ~ 20m, covering both near and far distance measurements
- Sunlight resistance: Capable of 12m ranging under 100Klux sunlight
- Dual target detection: Can simultaneously identify the distances of two targets (front and rear)
- Temperature compensation: Built-in temperature sensor for automatic temperature drift correction
- Reflectance calibration: Supports accuracy calibration for targets with different reflectance
- Dual interface: Supports UART and I2C communication, switchable via GPIO pin
1.2 NE301 Application Scenariosβ
In the NE301 sensor expansion board, the dToF module serves as a distance perception sensor, providing distance information for target snapshot capture. When a target enters the preset distance range, it triggers the NE301 to perform snapshot capture; the distance data can also be used as snapshot metadata to assist AI models in estimating target size.
| Application Scenario | Description |
|---|---|
| Smart Access Control | Detects personnel approach distance, triggering snapshot at close range |
| Robot Obstacle Avoidance | Provides obstacle distance data, assisting NE301 scene understanding |
| Vehicle Detection | Triggers NE301 snapshot within distance range, recording vehicle entry/exit |
| Industrial Inspection | Works with NE301 snapshots to quantify displacement or liquid level changes |
