Description

The HPS-166S-L utilizes Time-of-Flight (ToF) technology with a VCSEL laser source to calculate distance by measuring the round-trip time of a reflected infrared pulse. This method provides high accuracy and a strong signal-to-noise ratio, even in challenging lighting conditions. Integrated signal processing includes real-time compensation for environmental variables such as ambient infrared light and internal temperature drift.

Encased in a sealed, waterproof shell, the sensor is built to withstand demanding industrial and outdoor applications. Its RS485 Modbus interface ensures reliable communication over long distances, making it suitable for integration into distributed sensor networks, automated guided vehicles (AGVs), and unmanned aerial systems (UAS) for functions like altitude holding and obstacle avoidance.

Key Features

  • High-precision VCSEL laser-based ToF measurement principle.
  • Wide operating voltage range from 5V to 15V DC for flexible system integration.
  • Low quiescent power consumption of 0.1W for energy-efficient continuous operation.
  • Outputs comprehensive data including distance, accuracy, signal strength, ambient IR level, and sensor temperature.
  • Durable construction with an IP-rated waterproof ABS and aviation aluminum housing.
  • Wide storage temperature range from -40°C to +85°C for resilience in harsh conditions.
  • Narrow emission angle (±1.8°) minimizes crosstalk and enables precise targeting.
  • Optimized performance-to-cost ratio for high-volume industrial and commercial applications.

Applications

  • Drone and UAV altitude holding, soft-landing assistance, and frontal collision avoidance systems.
  • Industrial automation for pallet detection, empty bay monitoring in warehouses, and AGV navigation.
  • Security and perimeter monitoring for intrusion detection and height difference measurement.
  • Robotics for precise object localization and environment mapping.
  • Construction and logistics for vehicle load height measurement and bin level detection.

Frequently Asked Questions

What is the communication protocol for the HPS-166S-L sensor?

The sensor communicates exclusively via the RS485 physical layer using the Modbus RTU protocol. You will need an RS485 to UART/TTL converter module to interface with microcontrollers like Arduino or Raspberry Pi. The Modbus register map provides access to distance, signal strength, temperature, and other diagnostic data.

What is the operating voltage range, and how do I power it?

The HPS-166S-L operates from a wide DC input range of 5V to 15V. Connect the power supply to the designated V+ and GND terminals on the sensor's connector. Ensure your power source can provide up to 1.4W under maximum load. For stable operation, use a regulated power supply and consider adding protection against voltage spikes in industrial settings.

Can this sensor measure through glass or transparent surfaces?

No, ToF sensors like the HPS-166S-L typically cannot measure accurately through transparent materials like glass or clear plastic. The infrared laser pulse may reflect off the surface or refract, causing significant measurement errors. For reliable results, ensure the sensor has an unobstructed line of sight to a solid, opaque target.

How do I configure the output data rate and other parameters?

Configuration is performed via Modbus commands written to the sensor's internal holding registers. You can adjust the output data rate between 6Hz and 54Hz, and potentially set other parameters like filtering. Refer to the official Hypersen Modbus protocol documentation for the specific register addresses and command structure required for configuration.

Is the sensor suitable for outdoor use?

Yes, the sensor's waterproof ABS and aluminum housing provides protection against dust and water ingress, making it suitable for outdoor and harsh industrial environments. However, ensure the electrical connections are properly sealed. Performance in direct, bright sunlight may be affected, but the built-in ambient light compensation helps mitigate this.
