Who This Is For

You are replacing a broken sensor because your climate controller cannot make necessary adjustments without reliable data.
You are buying a backup probe because you need to ensure your monitoring system stays online during critical cycles.

What We Found

The 12ft cable length is enough to reach across most grow setups without needing an extra extension cord.
The stainless steel casing actually holds up against the constant moisture of a misting system better than plastic.

What Users Say

Users who swapped out their damaged sensors say they stopped seeing wild data swings on their controller display.
Operators who keep a spare on hand say they saved an entire batch when their primary probe failed mid-run.

VIVOSUN 12ft Temperature & Humidity Sensor Probe

A damaged or missing sensor probe shouldn't put your monitoring setup out of commission. The VIVOSUN VSS-THSP is a waterproof, stainless steel temperature and humidity probe built to work with the GrowHub Controller E42 and E42A, as well as the AeroLab THB1 and THB1S Hygro-Thermometer, giving you a reliable replacement or spare for any of these systems.

A 12ft cable and 2.5mm jack interface make it easy to position the probe exactly where you need accurate readings, whether that's deep in a grow tent or across a larger space. The stainless steel housing resists corrosion and moisture damage, so you can run the probe in humid grow rooms or near misting systems without worrying about long-term wear.

Reliable accuracy comes standard, with temperature readings within ±0.9°F and humidity readings within ±5%, giving you data you can trust for daily adjustments. Note that both the GrowHub E42A controller and the AeroLab THB1S already ship with a sensor probe included, so this is intended as a standalone replacement or for use with the original E42 and THB1 units.
