SensMax D3 Wireless People Counting Sensor

A compact, battery-powered bidirectional people counting sensor that delivers accurate footfall analytics and occupancy monitoring without cables or complex setup.

How It Works

The D3 uses three invisible infrared beams to detect movement through an entrance and determine whether a person is entering or exiting. Data is stored inside the sensor and sent automatically every 20 minutes to a SensMax gateway, which forwards it either to the SensMax Cloud, a local server, or third-party reporting tools. With accuracy of up to 99%, the system provides consistent, reliable results—even during busy hours.

 
How SensMax D3 works — infrared beams detect IN and OUT movements with up to 99% accuracy

Invisible infrared beams detect IN/OUT movement for precise bidirectional counting.

 

Easy Installation & Privacy

Installation takes only minutes: mount the sensor using adhesive tape or a small bracket and power it with standard AA batteries that last up to a year. After pairing with a gateway, counting starts immediately. The D3 records anonymous crossings only—no images or personal data—ensuring full GDPR compliance for public and private environments.

Technical Advantages

  • Directional detection — bidirectional algorithm distinguishes incoming and outgoing visitors.
  • Wireless setup — cable-free installation finished in minutes for rapid rollouts.
  • Periodic cloud updates — data uploads automatically (~every 20 minutes) to SensMax Cloud, local servers, or third-party reporting tools.
  • On-device backup — internal memory safeguards statistics during temporary connectivity outages.
  • Advanced reporting — configurable dashboards and occupancy monitoring in the online portal.

Real-World Applications

  • Retail stores — evaluate conversion rates by comparing visitor traffic with sales, adjust staff schedules during peak hours, and analyze campaign impact on customer flow.
  • Libraries & museums — measure attendance for cultural events, optimize opening hours, and secure funding with reliable visitor statistics.
  • Fitness clubs & gyms — identify busy times to improve equipment availability and schedule group classes effectively.
  • Corporate offices — monitor occupancy in meeting rooms and shared spaces, improving resource allocation and safety compliance.
  • Public buildings — plan cleaning services, manage security staffing, and better understand community facility usage.

Benefits for Business

By tracking real visitor traffic, managers can adapt staffing to peak times, optimize layouts, and measure the impact of marketing campaigns. Occupancy monitoring supports safety compliance, while the wireless design reduces installation costs and accelerates rollouts across multiple locations—delivering a faster return on investment.

Example in Practice

A retail chain in Central Europe installed D3 counters across 50 stores and discovered a consistent pre-lunch traffic peak. After adjusting staff shifts, they reduced waiting times and increased conversions in those hours by 12%.

Models & Range Options

  • Pro D3 — up to 50 m communication range.
  • D3 LR — up to 250 m range.
  • D3 SLR — up to 1000 m range.
