Gravity: KnowFlow Basic Kit – A DIY Water Monitoring Basic Kit

279.00

SKU KIT0131

KnowFlow is a water monitor, built specifically for environmentalists who want to monitor water quality in real time. The basic kit monitors two parameters – pH and electronic conductivity – using the Arduino platform. It is easy to customize by adding additional sensors and modules. Data is stored on a micro-SD card and can be viewed on the smartphone via Bluetooth

The KnowFlow AWM (Automatic Water Monitor) is the first kit for open-programming science from the KnowFlow team at the NGO GreenSeed Organization. It was originally designed for educational use, but they realized that many people need a water monitor, and began providing the plans to help build them

KnowFlow uses DFRobot’s Gravity Sensor series, which is easy to use and compatible. It can be powered by a power bank or Li-po battery, and can be customized with additional sensors such as ORP and dissolving oxygen

Attention: as a basic version of KnowFlow, this kit only includes pH and EC sensors
