Gravity KnowFlow DIY Water Monitoring Basic Kit
Features an Open-Source Science kit
Is designed for environmentalists
Monitors water quality and get real time data
Stores data on a micro-SD card
Is powered by power bank or Li-po battery

The Gravity KnowFlow DIY Water Monitoring Basic Kit is 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 Kits is using the DFRobot Gravity Sensor series. Gravity Sensor series are easy to use and high compatibility.

If you are not care about the code, you can just upload the sketch into the Bluno board without any coding job. After that you can find that the data is storing into the TF card.

KnowFlow can be powered by power bank or Li-po battery. For the advanced function, you may add ORP sensor, and Dissolve Oxygen sensor in your kit.
