Cookstove monitoring for $2

We lease SimpleSUMs for $36 per year. Most projects only need SUMs on 5% of stoves, or about $2 per stove per year for the fleet. Another reason $2 is the magic number: for carbon finance projects, an additional $2/ton usually covers the entire cost of SUMs.

Compatible with any cookstove

Developed specifically for cookstoves and adaptable by design. Attach it to any existing traditional, improved solid fuel, and LPG stoves. Or, build it into your cookstove from the beginning.

Performs in extreme environments

Strong enough to withstand the hottest fires in the roughest environments. Sophisticated enough to measure every meal. A Stove Use Monitoring System that works, no matter the weather.

Reliable data collection

When you can’t rely on cell service, you can rely on the Geocene SimpleSUM. Smartphone app and Bluetooth connectivity allow easy and instant data collection, even without internet access.
