Who This Is For

  • You are upgrading your climate control because your current setup fails to maintain target levels when lights shift
  • You are adding real-time monitoring because you need to catch CO2 drops before they slow down plant growth rates

What We Found

  • The white housing does a better job of reflecting heat than most black sensors on the market
  • We recommend this for anyone already using the E42A+ controller because the plug-and-play setup saves so much time

What Users Say

  • Users who added this to their automated systems say they spend less time checking gauges during the middle of the night
  • Growers who monitor CO2 with this probe report more consistent internodal spacing across their whole harvest

VIVOSUN 4-in-1 Environmental Sensor for GrowHub E42A+

Guessing at your grow room's climate costs you yield. The VIVOSUN VSE-CO2S4 4-in-1 Sensor tracks temperature, humidity, CO₂ levels up to 40,000 ppm, and light status in real time, then feeds that data straight to a GrowHub E42A+ controller so you can correct problems before they cost you a harvest.

The built-in NDIR CO₂ sensor works alongside your fans or CO₂ injection system to keep levels in the optimal range, helping plants photosynthesize efficiently without wasting energy or gas. A Swiss-made temp/humidity chip pairs with that CO₂ sensor to deliver readings you can act on immediately, while the white housing resists heat absorption for consistent results day after day, even under grow lights.

Built for tents, greenhouses, bedrooms, or cellars, the VSE-CO2S4 connects directly to the GrowHub E42A+ for remote monitoring and automated triggers, so you can manage your grow space without constant manual checks. Note that the probe is not compatible with the original E42 controller — it's built specifically for the E42A+.

Frequently Asked Questions

Does this sensor work with the GrowHub E42 controller?+

No. The probe is built for the GrowHub E42A+ specifically and is not compatible with the original E42 controller. Confirm your controller model before ordering.

What does the CO₂ sensor measure and how accurate is it?+

The built-in NDIR CO₂ sensor measures from 0 to 40,000 ppm with an accuracy of ±50 ppm or ±5%. This range covers everything from ambient air to supplemented grow rooms.

Can I use this sensor without a GrowHub controller?+

The sensor is designed to pair with the GrowHub E42A+ for remote monitoring and automation. Without the controller, you won't have access to the app-based data and trigger features.

How does the light detection feature work?+

The sensor detects whether your grow lights are ON or OFF, giving you a simple status reading alongside your temperature, humidity, and CO₂ data.

Where should I place the sensor for the most accurate readings?+

Position the probe at canopy height, away from direct airflow from fans or vents. The white housing helps minimize heat absorption for more consistent readings in tents, greenhouses, or grow rooms.

Is this sensor suitable for commercial grow operations?+

Yes. The 0-40,000 ppm CO₂ range and high-accuracy Swiss temp/humidity chip make it suitable for both hobbyist tents and larger commercial environments with supplemented CO₂.
