🌱 Hydroponic Monitoring Kit

🚫 Isolated Sensors

The EC and pH sensors are galvanically isolated from each other for reliable measurements.

🧪 pH

The pH sensor provides precise pH measurements, enabling you to maintain the ideal pH level for nutrient absorption and overall plant health.

💥 Conductivity

A conductivity sensor ensures accurate measurements of your nutrient solution. Maintain an optimal nutrient balance and prevent nutrient deficiencies or excesses for healthier plants.

🌡️ Water Temperature

Monitor temperature for hassle-free temperature compensation of conductivity and pH measurements.

🏠 Home Assistant Integration

Easily integrates into your Home Assistant ecosystem. Monitor your hydroponic system alongside other smart devices, and set up custom automations for greater functionality

🏗️ Assembled

The board, sensors, and connections are already made. You just need to put it in a box and integrate it into your system with an ESP32 or similar.
