Overview
LoRaWAN Based Warehouse People Counting System
Managing warehouse space without real data leads to underutilization, inefficiencies, and blind spots in restricted areas. In this case study, a LoRaWAN-based people counting system was deployed inside a warehouse to monitor restricted internal zones, providing real-time occupancy status and daily entry-exit tracking.
The solution captures live movement data to show whether a space is occupied or empty, how often it is accessed, and how long it remains in use all without manual intervention.
Before deployment, warehouse operators had no accurate way to measure how a specific area was actually used. Decisions were based on assumptions rather than data. By installing LoRaWAN people counting sensors at zone entry points, every in-and-out movement became a measurable event.
This enabled:
- Real-time warehouse occupancy monitoring
- Daily people in-out reporting
- Clear visibility into restricted area usage
- Data-driven space utilization decisions
The starting point
The Problem : No Real-Time Warehouse Occupancy and People Movement Data
Warehouses lack real-time visibility into how restricted internal areas are actually used, making it difficult to track warehouse occupancy, people movement, and space utilization accurately. In this case, the operations team had no automated way to know whether a specific zone was occupied or empty, how many people entered or exited daily, or how long the space remained in use.
Manual logs, CCTV reviews, and assumptions failed to deliver reliable data, resulting in underutilized space, inefficient planning, and limited control over restricted areas.
Without a warehouse people counting system, decisions were reactive instead of data-driven, directly impacting operational efficiency and ROI.
01
Limited Visibility
Traditional methods couldn’t provide accurate, real-time occupancy data for every zone.
02
Inefficient Space Management
Some areas were overcrowded while others remained underused, reducing operational efficiency.
03
Manual Tracking
Staff had to physically monitor foot traffic, increasing labor costs and errors.
04
Delayed Decision-Making
Lack of instant data caused slow adjustments in workforce deployment and storage allocation.
The approach
Solution : LoRaWAN-Based People and Occupancy Monitoring Using MacRay ToF Sensor
To solve the lack of visibility in restricted warehouse zones, the MacRay LoRaWAN ToF Sensor was deployed as a dedicated warehouse people counting and occupancy monitoring device. The sensor was installed at controlled access points to accurately track real-time warehouse occupancy, people entry and exit movement, and daily space usage without manual intervention.
Powered by Time-of-Flight (ToF) sensing technology, MacRay delivers precise people detection while eliminating false counts caused by forklifts, materials, or environmental interference. Using LoRaWAN wireless connectivity, the device transmits occupancy data over long distances with ultra-low power consumption, making it ideal for large warehouses, restricted areas, and industrial indoor environments.
01
LoRaWAN People Counter Integration
Installed MacRay LoRaWAN People Counters at strategic entry and exit points to track real-time movement and occupancy trends.
02
Zone-Wise Data Mapping
Each counter node transmitted occupancy data via LoRaWAN gateways, enabling zone-level analytics without relying on Wi-Fi or wired networks.
03
Smart Dashboard Connectivity
All data was fed to a central dashboard for live monitoring, space usage trends, and automated report generation.
04
Threshold Alerts for Optimization
Intelligent thresholds were configured to trigger alerts when zones reached critical occupancy levels, allowing dynamic workforce reallocation.
05
Minimal Infrastructure, Maximum Coverage
The low-power, long-range LoRaWAN network required minimal setup, perfectly suiting the massive warehouse layout.
06
Seamless SCADA Integration
Data was made compatible with the existing Amazon warehouse management system (SCADA) for smooth visualization and control.

On site
Deployment: LoRaWAN People Counters for Smart Warehouse Monitoring
The deployment was executed by installing MacRay LoRaWAN ToF people counting sensors on the top face of the door entrances leading into the monitored warehouse zones.
This placement ensured accurate detection of entry and exit movement while avoiding false counts from materials or equipment. Each sensor continuously tracked people in-out events and real-time occupancy status and transmitted data wirelessly over the LoRaWAN network.
In parallel, MacSet LoRaWAN controllers were integrated to provide visual occupancy indication inside the warehouse. When the defined occupancy threshold was exceeded, the system triggered instant visual alerts on-site and sent real-time notifications to all supervisors, enabling immediate action.
This deployment created a closed-loop system combining people counting, occupancy monitoring, visual alerts, and instant notifications, ensuring controlled access and safe utilization of restricted warehouse areas.

In closing
Conclusion: Eliminating Blind Zones to Build Safer, Smarter Warehouses
This deployment transformed a previously unmonitored warehouse zone into a fully visible, data-driven space. By implementing a LoRaWAN-based people counting and occupancy monitoring solution, the warehouse eliminated blind zones and removed the uncertainty around how restricted areas were actually used.
With real-time occupancy visibility, accurate entry-exit tracking, and instant alerts during over-occupancy, the operations team gained proactive control instead of reactive oversight. Supervisors could identify unsafe conditions early, enforce access limits, and respond immediately — significantly improving operational safety for both workers and assets.
Beyond safety, the solution delivered measurable operational value by improving space utilization, strengthening access control, and enabling data-backed decision-making. What was once an invisible area became a measurable, optimizable part of the warehouse, proving that real-time visibility is not just an operational advantage, but a critical component of modern, safe warehouse operations.
