AirComfort + – Wireless Temperature & Humidity Sensor AirComfort tracks temperature and humidity in your grow room and sends the data straight to your phone over Bluetooth. No more guessing at conditions, you get the actual numbers, so you can catch problems before they cost you a harvest. We've run one of these alongside a standard analogue thermometer and hygrometer in-store, and the readings matched closely throughout, with the added benefit of logged history rather than just a snapshot. It's also a well-built unit, picking up the German Design Award, the A' Design Award, and the Design for Asia Award. The compact shape fits into a tent or cupboard without getting in the way. Key Benefits 100 Days of Data Storage: Keeps logging even when you're out of Bluetooth range, then syncs everything once you're back in range Accurate Readings: Measures -25°C to 70°C (±0.5°C) and 0-100% humidity (±5%) Monitor Multiple Rooms: One app connects up to 32 separate AirComfort units, each labelled with its own name or icon Custom Alerts: Set alarms for temperature spikes or humidity drops so you catch problems early Long Battery Life: Runs on a single CR2450 battery for up to 12 months Flexible Logging Intervals: Set readings anywhere from every 5 to every 40 minutes, or refresh manually for real-time data How to Use Install the Battery: Unscrew the base, insert the CR2450 battery, and close it back up Download the App: Available for both iOS and Android Position the Sensor: Place or hang it in your grow room, ideally away from direct airflow for the most accurate reading Pair and Set Intervals: Connect via Bluetooth, name your unit if running more than one, and choose your logging interval Set Your Alerts: Add temperature and humidity thresholds so the app flags any changes automatically Best For Growers who want to actually see their grow room climate rather than guess at it Anyone running multiple tents or rooms who needs one app to track them all Diagnosing recurring issues like mould, stunted growth, or inconsistent yields tied to climate swings Common Questions How far does the Bluetooth range reach? Around 10 metres, depending on walls and obstructions. If you're out of range, the sensor keeps logging and syncs automatically once you're back within reach. Can I monitor more than one grow room? Yes. The app connects to up to 32 AirComfort units at once, so you can track several tents or rooms from a single app. How long does the battery last? Up to 12 months on the included CR2450 battery under normal use. Temperature and humidity swings are one of the most common causes of a struggling grow, and often the grower never sees them happening. AirComfort gives you the data to catch that early, rather than finding out at harvest. Read more in our AirComfort blog post, or see our full Thermometers & Hygrometers range.
