Level and proximity sensing
Sensors in the water need cleaning.
Your product has to know how full a tank is, and whether a cup is in place, without touching the water. We do it with time-of-flight distance sensing, and help you build it in.

How it works
From a depth sensor to a level reading
Water moves, reflects and fogs up, and every container is a different shape. Measuring from above keeps the sensor out of the water.
Your system: Tank and cup
The water in your tank, and the space under the spout.
Your system: Depth sensor
A time-of-flight sensor above the water.
Our solution: Surface finding
Finds the water surface, and any cup in place.
Our solution: Level reading
Turns the distance into a level for your tank's shape.
Your system: Dispenser
Fills, pours or warns at the level you set.
What it handles
Reads the level, not the ripples
We tune it to your container, then check each reading against a measured level, case by case.
What it measures
- Full and empty
- The top and bottom of your tank's range.
- While filling
- The level rising as water is added.
- While dispensing
- The level falling as water is drawn.
- Cup in place
- A cup or bottle under the spout.
- Your container
- The tank shape and material you use.
What it ignores
- Ripples
- Surface movement after filling or a knock.
- Bubbles
- Bubbles rising and settling.
- Condensation
- Droplets on the sensor window.
- Room light
- Sunlight and lamps near the product.
- Hands passing
- A hand passing without a cup.
Applications
Where it's built in
Your product gets the level, and whether a cup is in place, as they change.
Water dispensers
Tank level and cup detection under the spout.
Coffee machines
Water tank level, so the machine can ask for a refill.
Smart bins
Fill level, so bins are emptied when they need it.

Presence and fall detection
Knows when a room is occupied and when someone has fallen, without a camera image.
