SensMax SPS20 Solar Power System for Outdoor People Counting and Bike Counting Sensors

The SensMax SPS20 solar power system provides a reliable solar power source for outdoor people counting and bike counting radar sensors in locations without electricity. It is designed for SensMax outdoor TAC-B radar sensors, including TAC-B 3D-WP and TAC-B 4G, where a wired power connection is not available or is too expensive to install.

SPS20 combines a solar panel, charge controller and LiFePO4 rechargeable battery into one compact system. It keeps outdoor people counting sensors working in parks, trails, public spaces, Smart City areas, nature reserves, marinas, outdoor attractions and other remote locations.

With up to 65-85 hours of backup operation without sunlight, depending on sensor settings, SPS20 helps maintain continuous visitor monitoring even during cloudy periods, evenings and short periods of poor weather.

How the SPS20 Solar Power System Works

The SPS20 captures solar energy through a 20W mono solar panel and stores it in a LiFePO4 rechargeable battery. A smart charge controller manages the charging process and delivers stable power to the connected outdoor people counting or bike counting radar sensor.

During daylight, the solar panel charges the battery and powers the connected sensor. When sunlight is not available, the battery continues to supply power. Depending on the sensor settings, SPS20 can provide approximately 65-85 hours of backup operation without sunlight.

The controller protects the battery from overcharging and deep discharge. This helps extend battery life and keeps the sensor operating reliably in outdoor installations.

Power for Off-Grid Outdoor Counting Projects

Many outdoor people counting projects are delayed or made more expensive because there is no nearby power supply. Installing new electrical cabling can require permits, civil works, contractors and long approval times.

SPS20 solves this problem by providing a local solar power source for the sensor. It allows SensMax outdoor radar counters to be installed in locations where wired power is not available, such as nature trails, parks, riverside paths, beaches, outdoor attractions and temporary event areas.

This makes deployment faster and reduces the need for infrastructure work. In many projects, the sensor and solar power system can be installed once the mounting point is prepared.

Designed for SensMax Outdoor TAC-B Sensors

SPS20 is designed to power SensMax outdoor TAC-B radar sensors used for pedestrian and bicycle counting. It is especially useful with SensMax TAC-B 3D-WP and SensMax TAC-B 4G sensors in outdoor locations.

The system provides 12V DC power through a DC5521 connector compatible with SensMax TAC-B sensors. It is suitable for long-term visitor monitoring projects where continuous operation is required but wired power is not available.

Typical Applications

SensMax SPS20 is suitable for outdoor people counting and bicycle counting projects where power infrastructure is limited or unavailable.

• Parks and green spaces for visitor flow monitoring without new electrical cabling.
• Walking trails and nature paths for off-grid pedestrian counting.
• Bicycle routes for outdoor bike counting in remote or semi-remote areas.
• Smart City projects where sensors are installed on poles, lamp posts or public infrastructure.
• National parks and nature reserves for long-term visitor statistics with minimal infrastructure impact.
• Outdoor events and temporary venues where power cables or generators are not practical.
• Beaches, marinas and tourist attractions for seasonal visitor monitoring.
• Urban redevelopment areas where visitor data is needed before permanent infrastructure is installed.

Business Benefits

SPS20 helps municipalities, park operators and public-space managers collect visitor data in places where sensors could not be installed easily before. It removes the need for a nearby electrical connection and reduces the cost and time required for deployment.

Reliable outdoor counting data helps plan maintenance, cleaning, waste collection, staffing, funding requests and public-space improvements. With solar-powered sensors, operators can monitor remote locations over long periods and compare visitor traffic between different sites.

• avoid costly trenching and electrical installation work;
• deploy people counting sensors faster in remote locations;
• collect long-term visitor statistics in parks, trails and public areas;
• support sustainability goals with renewable power;
• justify maintenance budgets and infrastructure improvements with real data.

Example in Action

A municipality wants to monitor visitor flows on a popular riverside walking trail. A wired power connection is not available near the best sensor location, and installing new electrical cabling would require permits, contractors and extra cost.

By using the SensMax SPS20 solar power system together with outdoor TAC-B radar sensors, the city can install the counting system without connecting to the electrical grid. The sensors start collecting pedestrian and bicycle data, and the city uses the statistics to plan maintenance, improve services and support funding requests for future trail development.
