The Grow Sensor PRO is a canopy-level monitoring system built for serious indoor growers. It measures light, climate, and plant response in real time - so you can dial in your environment and produce consistent, high-quality harvests.

Instead of juggling multiple sensors and apps, Grow Sensor PRO gives you complete environmental insight in one calibrated system.

One Sensor. The Whole Environment.

Most grow rooms rely on multiple devices scattered around the room. That creates data gaps and makes it difficult to see what the plant is actually experiencing.

Grow Sensor PRO measures the key signals together at canopy level, where plant physiology responds to its environment.

This allows you to see relationships like:

• How light affects leaf temperature
• How climate conditions influence VPD
• How irrigation impacts the root zone

When these signals are measured together, cause and effect becomes clear.

WHO IT’S FOR

Grow Sensor PRO is built for growers who want to improve consistency and performance.

It’s ideal if you:

• Grow indoors
• Run multiple plants, zones, or crop cycles
• Make decisions based on data and trends
• Want consistent environmental targets across a room

Built for Real Grow Rooms

Designed for growers who actively manage their environment.

• Battery life from 2 weeks to 3 months depending on sampling rate
• USB power option
• 2.4 GHz WiFi connectivity
• Offline data logging if internet drops
• Tripod mountable
• Compact form factor for any grow size
• Home Assistant compatible
• API access for integrations

WHAT IT MEASURES

Climate & environment

• Air temperature
• Relative humidity
• CO₂
• Dew Point
• Atmospheric pressure
• Ambient VPD

Light & photosynthesis

• ePPFD (extended spectrum)
• ePAR (extended spectrum)
• eDLI (extended daily light integral)

Lighting is one of the biggest drivers of plant performance. PPFD, spectrum, and daily light integral (DLI) 24/7, allowing you to maintain consistent light targets throughout the crop cycle.

Plant response

• Leaf surface temperature (infrared)
• True leaf VPD (not estimated)
• Leaf-to-ambient temperature differential

Substrate & root zone

• Measured via SDI-12 substrate probe models* (not included)
• Substrate EC
• Water content
• Substrate temperature

*see technical specifications for the full list.

All sensors are factory calibrated before shipping to ensure long-term accuracy and consistency.

This System is Not Built for Everyone

This system may` not be the right fit if:

• You grow outdoors only
• You want the cheapest monitoring option
• You only need a simple thermometer/hygrometer
• You don’t plan to actively use the data

Grow Sensor PRO is designed for growers who actively refine their environment each cycle.
