LoRa sensor for rainwater:
monitor your tank easily
Efficiently manage your rainwater reserve with a connected LoRa sensor. Real-time alerts, consumption monitoring and leak detection.
You have invested in a rainwater harvesting tank. You water your garden, supply your toilet or washing machine with this free water. But do you know exactly how much water you have left? A connected LoRa sensor installed in your tank gives you access to this information in real time, from your smartphone.
LoRa (Long Range) technology is particularly suitable for rainwater tanks, often buried or located outdoors. It offers long-distance range, several years of battery life and foolproof reliability. In this article, discover how this small sensor transforms your rainwater management.

water_drop 1. How does a LoRa rainwater sensor work?
The tankio sensor for rainwater tanks uses the hydrostatic pressure measurement. A pressure sensor placed at the bottom of the tank measures the pressure exerted by the water column. The more water, the higher the pressure. The microprocessor converts this pressure into a precise filling level, expressed in liters or as a percentage.
The casing and membrane are designed to resist standing water, UV (if the tank is above ground) and temperature variations. The sensor is waterproof and can be permanently immersed without risk of damage.
Data is transmitted via the LoRa network to a gateway and then to the tankio cloud. You view your water level in real time from the mobile application or the web dashboard. To discover the full range, visit our page dedicated to sensor for rainwater tanks.
visibility 2. Monitor your reserve without opening the tank
One of the great advantages of the connected sensor is that it saves you from opening the tank to check the level. Rainwater tanks are often equipped with heavy lids that are difficult to handle. Without a sensor, there is a great temptation not to check, to the point of running out of water when watering the plants in summer.
With the tankio sensor, you open the application and you instantly see:
- The current level of your tank in liters and percentage.
- The estimated date of the next significant recharge period (weather dependent).
- The volume of water used today, this week and this month.
- Water temperature (useful for outdoor uses).
No more manual inspections: you know at a glance whether you can water the garden, wash the car or whether you need to save the reserve while waiting for the next rain.
plumbing 3. Real-time leak detection
A leak in your rainwater circuit can go unnoticed for weeks. The tankio LoRa sensor automatically detects abnormal drops in level and alerts you immediately.
How does it work? The sensor records the level of your tank at regular intervals (for example every hour). It calculates normal consumption based on your habits. If the level drops faster than expected without explanation (no water use, no drought), an alert is triggered.
This is particularly useful for buried tanks with invisible pipes. A leak can represent hundreds of liters of water lost each week. With the sensor, you are notified within a few hours, which allows you to intervene quickly and avoid waste. To learn more about installation, see Connected Gauge FAQ.
monitoring 4. Tracking water consumption
The tankio sensor does more than just display the current level. He keeps the complete history of your rainwater consumption. You can view your consumption in graphs and identify your usage peaks.
This data is valuable for understanding your habits: how much water do you use for the garden in summer? Is your consumption stable or is it increasing from year to year? Can you correctly size your future tank if you move?
Historical monitoring also makes it possible to detect progressive changes in behavior. For example, if your rainwater consumption suddenly increases but your habits have not changed, this may indicate a slow leak in the distribution network.
eco 5. Optimize your use of rainwater
Knowing your rainwater level precisely allows you to optimize your consumption. No more drawing mains water when your tank is full without knowing it!
The sensor helps you:
- Water at the right time: you know if the reserve is sufficient for the planned watering weekend, or if it is better to wait for the forecast rain.
- Switch to mains water: in the event of prolonged drought, the sensor alerts you when the level becomes critical for priority uses.
- Plan heavy uses: car wash, swimming pool filling, patio cleaning. You choose the time when the reserve is most abundant.
- Evaluate your return on investment: in liters saved per year, you calculate precisely what your rainwater harvesting installation brings you.
In regions where water becomes a precious resource, the connected sensor is an essential tool for responsible management. To learn more about recovery systems, see our article rainwater harvesting with pump.
build 6. Installation and configuration
Installing the LoRa sensor for rainwater tanks is quick and easy. It does not require no specialized tools or professional intervention in most cases.
Installation steps
- Locate the access point to your tank: upper manhole or technical manhole.
- Insert the sensor at the bottom of the tank, using a strap or float, or let it sit at the bottom.
- Connect the cable from the sensor to the LoRa transmission module (placed out of water, under the cover or nearby).
- Turn on the module : the battery is pre-installed, simply remove the protective tab.
- Activate the sensor in the tankio application.
The entire operation takes less than 15 minutes. The LoRa gateway, if you don't already have one, connects to your internet router in a few seconds and covers a radius of several hundred meters.
