▀▀▀▀Meet Seto.
Your friendly water drop that watches over liquid containers so you don't have to.
Liquid containers
are vulnerable.
Fuel tanks, water reserves, chemical drums — losses go unnoticed until someone physically checks.
Invisible losses
Siphoning and leakage happen silently. Without continuous monitoring, the damage is discovered too late — during manual inspection or inventory counts.
Existing tools don't fit
Current solutions are expensive, single-parameter, or designed for lab environments. Not practical for the kind of continuous, remote monitoring real-world storage needs.
Accessible hardware,
open-source software.
Meaningful environmental monitoring shouldn't require specialized equipment or a huge budget.
$15
Total hardware cost
An ESP32 and an ultrasonic sensor. That's the whole node. No proprietary equipment.
Real-time
Anywhere access
Data streams to the cloud over WiFi. Check on your containers from any browser, on any device.
Extensible
Beyond liquid monitoring
Edge sensing + cloud dashboards. The same pattern works for water quality, agriculture, or industrial processes.
Sensor to screen
in three steps.
Measure
An ESP32 reads distance and temperature from sensors on a container at regular intervals.
Transmit
Readings stream over WiFi to Firebase, stored with timestamps for historical analysis.
Visualize
A web dashboard plots live trends and surfaces alerts when readings deviate from baseline.
