Take full command of your grow environment with the Mars Hydro Smart Sensor Kit, designed for use with the iControl Controller or iHub Pro. This intelligent three-sensor system allows growers to monitor and automate critical conditions — light intensity, CO₂ concentration, and soil health — ensuring precision control and maximum plant performance throughout every growth stage.

Features & Benefits

PPFD Sensor – Optimize Light Intensity
Monitors real-time Photosynthetic Photon Flux Density (PPFD) and adjusts lighting automatically to maintain ideal PAR levels for each growth stage. Maximizes light efficiency and plant development.
CO₂ Sensor – Enhance Growth & Yield
Tracks live CO₂ concentrations and integrates with your inline fan or CO₂ generator to maintain the optimal range for photosynthesis. Helps improve biomass production and overall yield.
Soil Sensor – Protect Root Zone Health
Measures soil temperature, moisture, and EC (electrical conductivity) with accuracy. Enables precise irrigation and fertilization management, preventing overwatering or nutrient imbalance.
Seamless Integration
Works directly with the Mars Hydro iControl and iHub Pro systems for full automation and environmental synchronization.
Reliable & Durable Design
Built for consistent performance in indoor grow environments. Simple to install and calibrate with included RJ12 cables and T-splitters.
