VIVOSUN Wireless Thermometer & Hygrometer Set

See what your plants are actually experiencing, in every zone

The VIVOSUN Wireless Thermometer & Hygrometer pairs a main display unit with three wireless sensors, so you can watch temperature and humidity in several places at once - inside the canopy, out in the lung room, and outdoors as a reference. Readings come through on a large LCD screen and the signal carries reliably through walls and tent fabric, so the sensors go where the information is rather than where the cable reaches.

What's Included

• 1 x main display unit with large LCD screen showing all three zones
• 3 x wireless temperature and humidity sensors
• User manual

Key Benefits

• Three wireless sensors cover tent, lung room and outdoor conditions at the same time.
• Accurate digital readings for both temperature and relative humidity.
• Large LCD display shows every zone at a glance, no app needed.
• Wide signal range transmits through tent walls and room partitions.
• Compact and repositionable - move a sensor to chase a hotspot or a new space.
• Battery operated: insert, place and read.

Why Does One Sensor Miss So Much?

A grow tent is not one uniform environment. Heat rises to the top of the canopy, intake air arrives cooler than everything around it, and humidity pools under the leaves where airflow is weakest. Reading a single point at head height says almost nothing about the microclimate plants actually live in, which is how growers end up chasing mould, slow growth and stubborn humidity without finding the cause. Three sensors show how conditions shift across the space, so you can stabilise temperature, balance RH and keep VPD in range.

How to Use

Insert batteries into the display unit and each sensor, then place the sensors where you need the data: one in the canopy, one in the lung room, one outside as a reference. Check the LCD screen for live readings from all three zones, and reposition a sensor whenever you need to track down a hotspot or a dead spot in your airflow.
