Know what's in your tank.

TankSense sits on the lid of your polytank and tells your phone how many litres you have, when mains water starts flowing, and when you will run dry. No climbing, no tapping, no surprises.

Launching in Accra in 2027, then the US. Solar powered, works on MTN, no Wi-Fi needed.

Why Accra keeps a tank

Ghana Water produces about 219 million gallons a day. Accra and the other cities it serves need 350 million. So the tap runs when it runs, and the tank on your stand is what you live on.

Days of piped water a week, by neighbourhood. In the April to June dry season, supply can fall to 2 to 3 days or less.

Ten minutes to fit. Then it watches for you.

  1. Fix it through the tank lid

    A threaded collar and lock nut hold it in place. No wiring, no plumbing, no Wi-Fi to set up.

  2. It measures every five minutes

    A radar or ultrasonic sensor reads the water level from above. A small solar panel and a long-life LiFePO4 battery keep it running for months without sun.

  3. Your phone does the checking

    Readings go over the mobile network to the TankSense app, which turns them into litres, days left and alerts you can act on.

The app tells you what to do, not just a number.

TankSense learns how your household uses water and when your area's supply usually comes, so its alerts arrive while you can still do something about them.

Sample screen

Water is flowing

The moment mains water starts filling your tank, day or night, so you can open the inlet or start the pump.

Days left

Litres in the tank and how long they will last at the rate your household uses water.

Running low

A warning at the level you choose, early enough to arrange water before the taps go dry.

Unusual drop

Water leaving the tank when nobody should be using it: a leak, a running toilet or an open tap.

Overflow

A full tank still filling, so you can shut the inlet and stop wasting water.

Refill in one tap

Coming in 2028: order a water tanker from a vetted local vendor and pay with mobile money.

Who is building it

TankSense is being built by Pixel Resolve. The founder, Leonard Eshun, studied computer engineering at KNUST in Kumasi. From 2007 to 2024 he designed and led development of the system that processes every current Ghanaian and Liberian passport, growing it from one location to more than 85 worldwide, including 65 embassies. He now builds production AI systems.

He designed the TankSense prototype, from its power system and circuit board to its firmware and cloud, and is building three prototypes now: two for a full-height test tank in Durham, North Carolina, and a field unit for Ghana.
