Capacitive sensor strips adhered to the outside of a black Rotoplas tinaco — thin, flat strips running vertically along the tank exterior. The non-invasive nature is the visual story.

Sensor Capacitivo de Nivel de Agua MirAqua
Mide a través de la pared — sin necesidad de entrar al tanque
Sensor capacitivo externo que mide el nivel de agua a través de la pared del tanque sin perforación ni contacto con el agua. Ideal para tinacos de polietileno, tanques de plástico, e instalaciones donde no es posible perforar o montar internamente.

The most affordable entry point to smart water monitoring — especially at early adopter pricing. For homeowners who primarily want tinaco level tracking and low-water alerts, this is the right technology at the right price.
Cómo Funciona
Capacitive sensing measures changes in electrical capacitance caused by the presence or absence of water on the other side of the tank wall. Water has a dramatically different dielectric constant than air — the sensor can reliably detect whether water is present at each sensor point without any physical contact with the water.
Sensor strips are adhered to the outside of the tank at multiple heights. Each strip reports whether water is present at its level. The combined readings produce a stepped level indication: “above 75%”, “between 50-75%”, “between 25-50%”, “below 25%”.
Best For
Capacitive sensors excel on plastic tinacos and polyethylene tanks — the most common tank type in Los Cabos rooftop installations. They’re the ideal monitoring solution for tinacos because: no lid removal needed, no internal access required, no humidity exposure, and no interference with the float valve mechanism.
For underground concrete cisterns, ultrasonic or pressure sensors are better suited — concrete walls are too thick and variable for reliable capacitive sensing.
The Cost Advantage
Capacitive sensors are the most affordable entry point to smart water monitoring. For homeowners who primarily want to track their tinaco level and receive low-water alerts, this is the right technology at the right price point. Pair with an ultrasonic sensor on the cistern for complete two-tank monitoring.
