Indispensable as a nutrients and pH controller, water tank level manager or even a security system.

It can control any 12v actuators like water valves or peristaltic pumps, while also analyzing the water solution in your tank thanks to the pH, EC, Temperature and water level sensors.
Refill the tank, recycle the water and even automatically control the nutrients and pH.

TankBot is the most versatile and precise module in the GroLab™ family. It could be described as a complete controller that is able to cover all the aspects of tank management. However, this description is not enough because TankBot is much more than that. PH & water temperature regulation, nutrients dosing, water level management and tank refill/drain are just some examples of the TankBot capabilities.

TankBot configuration schematic, nutrients controller, PH controller, used also as a security for motion and smoke detection.

Power Supplier

TankBot can provide power to all peripherals of your growing environment. It has 4 connectors that support 12VDC~24VDC actuators allowing a wide variety of devices from small water pumps, peristaltic pumps, relays, power contactors, etc.

PH Monitor & Adjustment

This module gives you the possibility to deep analysis, monitor and control the pH. The GroLab™ system programmable procedures offers several options to regulate pH based on the user needs.

EC Monitor & Analysis

TankBot also supports EC probe extending the monitor and control of your water tank to another level. GroLab™ system can notify you and even react based on electrical conductivity of your water.

Water Temperature

TankBot provides all you need to continuously regulate the water temperature ensuring the optimum conditions for your plants to grow.

Nutrients Dosing

Connecting peristaltic pumps on TankBot opens the door to the nutrients dosing domain. GroLab™ system provides all the necessary tools to calibrate the peristaltic pumps and to create procedures to pump the exactly amount of milliliters required.

Speed Customization

TankBot provides the capability to customize device speed. This feature can improve the precision even with low cost devices.

Advance Irrigation

Thanks to the capability of handling actuators of 12v, it is possible to create impressive irrigation systems that can independently feed multiple grows.

Tank Level Management

This module supports 4 extra switch sensors of your choice like water level sensors, allowing to continuously monitor the water level of your tanks. With the right peripherals connected to the TankBot, like solenoid valves or water pumps, user can create procedures to automatically drain and refill, allowing a complete tank maintenance.

Safety Protocols & Procedures

TankBot allows you to create safety protocols & procedures to avoid risk situations or even react to them in order to minimize the damage. Fires and intrusions are some examples of risk situations this module can handle. The cool-down feature prevents damage to devices that need some time to cool down before turning them on.

Module Communication

TankBot communicates with GroNode (the system’s core module) through radio frequency with a range of 25 meters indoors (depending on obstacles) and 100 meters in open spaces. This makes it easy to install the TankBot close to the water tank.
