Home Assistant Smart Home (LD2451 Rear Vehicle Detection)

Introduction: The LD2451 radar module supports rear vehicle detection with LED light prompts (who drives without playing music? So playing prompts is somewhat redundant; it’s better to use light prompts directly). It can only be used as an auxiliary; good driving skills still require frequent checking of the rearview mirror.Wiring Diagram: //#include <SoftwareSerial.h>// Source code … Read more

Essential Considerations for Installing Ground Loop Sensors in Parking Systems

Principle of Vehicle Detectors and Ground Loops in Parking Lots   1. Working Principle   Ground loop vehicle detectors are based on the principle of electromagnetic induction. They are typically embedded under the roadbed of the same lane in a circular loop, powered by a working current, acting as a sensor. When a vehicle passes over or … Read more
