What does the VIVOSUN AeroLab Hygrometer Thermometer measure?
It tracks temperature, relative humidity (RH), and VPD (Vapour Pressure Deficit), helping you fine-tune grow conditions. It connects via Bluetooth to the VIVOSUN app for real-time data, alerts, and logging. VPD is calculated from air temp and humidity—not leaf temp—but is still highly useful for growers.
What is dual-channel monitoring, and how do I use the external sensor?
The device includes an internal sensor and an external probe so you can monitor two areas (like canopy vs floor). Place the probe at plant level, avoiding direct airflow or moisture. You can hang, mount, or stand the unit where it’s easy to view.
Do I need the VIVOSUN app to use this device?
No—the LCD screen shows live readings. But the app unlocks advanced features like data logging, high/low alerts, and trend tracking. You’ll need an account to sync and access full app functionality.
Can it send alerts or track grow room history?
Yes—you can set temperature and humidity thresholds in the app. It logs data over time so you can monitor trends, export records, and catch issues like sudden spikes or drops.
What’s the Bluetooth range, and will it work through grow tent walls?
Bluetooth performs best line-of-sight. Tent walls and interference can reduce signal strength. If you have connection issues, try moving your phone closer or restarting the device and app. You can also connect multiple sensors and rename zones.
What type of batteries does it use, and how long do they last?
It runs on AAA batteries (often included). Battery life depends on usage but is designed for long runtime. Most models include a low-battery warning, and you can switch between °C/°F and view high/low records on the screen.
Does it work with other VIVOSUN smart controllers?
Yes—it integrates with VIVOSUN GrowHub systems for remote monitoring and automation. For multiple rooms, use one unit per zone or a second AeroLab device. Direct Wi-Fi access requires pairing with a compatible controller.
Can I use this in grow tents, greenhouses, or drying rooms?
Yes—it’s ideal for indoor grow environments. Use it in grow tents, drying or curing rooms, nurseries, greenhouses, and hydro setups. Keep the unit dry and protected from direct spray or condensation buildup.
Is the AeroLab Hygrometer waterproof?
No—the main unit and probe are not waterproof. They’re fine in humid conditions but should not be exposed to water splashes, direct mist, or standing water. Treat it like any electronic sensor: keep it dry for best lifespan.
How do I check or calibrate the device’s accuracy?
You can verify humidity accuracy with a salt test (sealed container + salt slurry). Most models don’t offer manual calibration, but you can account for any offset once you know it. Sensor drift is normal over time—recheck accuracy every few months.
Why do readings jump or differ from other hygrometers?
Sensor placement matters. Airflow, nearby equipment, and microclimates can cause variation. Readings may also shift during lights-on/lights-off transitions due to temp and RH changes. For fair comparison, place meters side-by-side for a few hours.
Is the VIVOSUN AeroLab beginner-friendly?
Yes—it’s easy to use out of the box, with clear readings and simple setup. The app adds power-user features like alerts and data logging, but even beginners can monitor RH and temp without needing to learn complex systems.
What’s included in the box?
The AeroLab device, an external probe, and AAA batteries (commonly included). It’s ready to use immediately—just place, power on, and start monitoring.
What should I do if the screen is blank or readings look wrong?
Check or replace the batteries, ensure correct placement (not near heaters or humidifiers), and let it stabilize. For odd readings, compare with another meter and consider verifying with a humidity test.
Any tips for getting the most accurate grow readings?
Place sensors at canopy height, away from direct airflow or humidifier streams. Use the external probe to monitor microclimates or hard-to-reach areas. Let the meter run 24/7 for continuous tracking and more stable environments.
