1. Product Overview
The Induskey INK424 is a non-contact laser remote sensing road-surface temperature monitoring device. Using infrared laser remote sensing technology, the sensor measures road surface temperature without the need for road cutting or lane closure. Housed in a waterproof, corrosion-proof metal enclosure, the INK424 delivers accurate data across a wide range of weather conditions, enabling road management authorities to take preventive measures before safety hazards occur. The sensor can be permanently mounted on a roadside pole for long-term monitoring, or deployed on a vehicle for mobile testing applications. With ultra-low power consumption below 1W and dual power input options, the INK424 is ideal for both grid-connected and solar-powered remote installations.
2. System Architecture
The INK424 operates as a fully integrated infrared road temperature sensing unit with the following core components:
-
Infrared Laser Emitter: Directs an infrared laser beam at the road surface from the roadside-mounted sensor head.
-
Optical Receiver & Signal Analyzer: Captures reflected infrared signals and analyzes them to determine road surface temperature with high accuracy.
-
Signal Processing Unit: Calculates temperature values with ±0.5°C accuracy and 0.1°C resolution across the full -40°C ~ +80°C range.
-
RS485 Communication Module: Reliable wired digital output for integration into existing highway automatic weather monitoring networks.
