What does the GroLab Doser Kit allow me to control?

This configuration allows you to automatically dispense the precise amounts of fertilizer A & B to your solution whenever the tank is refilled or whenever you schedule it.

PH is automatically set to the value you define by automatically compensating raise or falls in your solution. And the water levels are constantly analysed trough the level sensors available in this kit.

TankBot is also a powerful security tool, since you can sample any switch sensor, like smoke or motion detectors, allowing you for example to shutdown all your room, or even the whole system and send you an e-mail when, someone gets to near, or smoke is detected. Notifications, selective shutdown, are just some of the procedures you can configure.

You still get a free output and 2 inputs to use the way you find suitable.

GroLab Doser Kit stores every sensor data and output state, providing a track of your grows from seed to fruit, enabling you to maximize your growth and efficiency!
