Product Overview

Gravity KnowFlow basic kit is a DIY water monitoring basic kit Know. It designed for environmentalists who want to monitor water quality and get real time data. It can monitor 2 parameters with basic kit (pH and electronic conductivities). The kit is based on Arduino, easy to change and add more sensors and modules. Currently it stores the data on a micro-SD card, also the data can be viewed on your smart phone via Bluetooth communication. KnowFlow AWM (Automatic Water Monitor) is the first kit for open source science in KnowFlow team. KnowFlow team comes from NGO GreenSeed organization. KnowFlow kits is using the DFRobot gravity sensor series. Gravity sensor series are easy to use and high compatibility. KnowFlow can be powered by power bank or Li-po battery.
