Product overview
The Meskernel LDK-P4 uses infrared phase-shift ranging to measure distances from 0.03 to 40 meters with ±1–2 mm accuracy. Its 20Hz measurement frequency supports object positioning, range control and industrial distance monitoring. Applications include robotic obstacle detection, SLAM mapping, agricultural equipment monitoring, warehouse automation and construction measurement integration. The Class 1 eye-safe infrared laser supports indoor and outdoor operation in controlled environments. UART / TTL communication provides a connection for embedded hardware and automation systems.
The compact, lightweight module measures 75*47*21.05mm and weighs 71g, with IP54 ingress protection and an operating temperature range of -10 to 50°C. It operates at 3.3V / 5V and offers low power consumption for mobile and embedded devices. Integration options include Arduino UNO, Mega and Nano, ESP32, STM32 and Raspberry Pi 3/4, plus industrial PLCs via UART conversion. Detailed communication protocols support integration, with Arduino IDE, Python and C/C++ compatibility. The sensor is packaged in an anti-static bag and carton and carries a one-year warranty.
