The UserBot is an Arduino shield that enables the creation of a fully customized GroLab™ module. Aimed at users with basic knowledge of programming and electronics, it offers a simple way to integrate third-party sensors and devices into the GroLab™ ecosystem.

This solution stands out for its flexibility, creativity, and total control over the system, making it ideal for those who need a setup tailored to the specific requirements of their grow or project.

UserBot connects directly to the Arduino, eliminating the need for external power, and allows the connection of custom circuits, devices, and sensors. It is a plug-and-play solution compatible with virtually any component required for the desired configuration.

All functionalities are defined by the user, including:

• Developing remote controls that operate based on pre-programmed actions;
• Creating portable sensors capable of measuring pH, electrical conductivity (EC), temperature, CO₂, and other variables;
• Adding support for technologies such as infrared communication or Bluetooth;
• Measuring analog voltages using Arduino pins or external analog-to-digital converters (ADCs);
• Controlling devices through relays, motors, or other actuators.

UserBot includes full support for radio frequency communication and features a development board with accessible connections for sensors and additional circuits.

The purchase of sensors, peripherals, and replacement parts compatible with the GroLab™ system can be made through the Open Grow online store or via GroLab™ resellers.

UserBot allows any Arduino project to become a fully integrated module within the GroLab™ ecosystem. Thanks to its compatibility with a wide range of sensors and devices, it opens the door to countless automation and monitoring possibilities for grow environments or other customized applications.

In the illustrated configuration, UserBot installed on an Arduino controls four lines on an electrical panel via relays, activating and deactivating lighting and extraction systems in a grow room — with two lines free for future expansions. It simultaneously manages a solenoid valve for automatic filling and three peristaltic pumps: one for pH regulation and two for dosing nutrients A and B. At the same time, it collects data from the GroLab™ CO₂ Compact Sensor, ensuring integrated monitoring and automated control of the growing environment. This example highlights UserBot’s versatility in managing multiple devices within a fully customizable module, simplifying advanced automation.

To simplify the prototyping process, the UserBot includes an integrated breadboard that is compatible with various packaging types: through holes, 1206, 0805, 0603, DIP, TO-92, TSSOP-16, SOIC-16, SSOT223, and SOT26.
Components can be soldered directly onto the board, allowing users to build more robust and reliable solutions.
