Digitally upgrade rainwater tanks
With Senvolon level sensors, landscaping companies can digitally upgrade rainwater tanks easily, precisely, and with low maintenance. No cloud required and no special IT knowledge needed.
Why classic solutions often cause problems
Float switches, ultrasonic solutions, or simple IoT sensors seem practical at first, but in practice they often cause unnecessary support work. For landscaping companies, this means follow-up visits, dissatisfied customers, and shrinking margins.
Sticking floats
Mechanical parts can wear out, get stuck, or deliver incorrect readings.
Fluctuating readings
Temperature, humidity, or reflections can affect simple measuring systems.
Cloud dependency
Many IoT systems only work reliably as long as external servers are reachable.
Contactless measurement with LiDAR or radar
Senvolon level sensors measure contactlessly from above onto the water surface. No moving parts, no mechanical wear, and precise readings for your customers.
| Feature | LiDAR | Radar |
|---|---|---|
| Measuring range | Up to 12 m | Up to 40 m |
| Accuracy | Centimeter-accurate | Millimeter-accurate |
| Suitable for | Liquids and solids | Liquids. Ideal for larger tanks and demanding environments, very robust against steam, fog, and condensation |
Both versions are compact and easy to install.

Also suitable for underground tanks and concrete rainwater tanks
Especially with underground rainwater tanks, Wi-Fi reception in the shaft is often a challenge. That is why Senvolon level sensors are also available with an external Wi-Fi antenna connector. The antenna can be positioned outside the shaft.
More than just fill level
Precise fill level detection opens up additional applications around irrigation, pump control, and smart garden automation.
Pump control
Pumps can be automated via the integrated switching output or smart home systems.
Avoid dry running
Alerts for low fill levels protect equipment and irrigation systems.
Sustainable irrigation
Transparent readings support a more mindful use of rainwater.
Matching level sensors
Choose the right variant depending on tank size, installation situation, and reception conditions.
