AirComfort+ Wireless Temperature & Humidity Sensor - Bluetooth Grow Room Monitoring
Best for: Growers who want reliable temperature and humidity tracking in a tent or grow room without paying for a full climate controller.
Our thoughts
Knowing what's actually happening in your tent overnight is half the battle with VPD and mould prevention, and this does that job without the price tag of a full climate control ecosystem. The 100-day offline logging is the standout feature — it keeps recording even if you've wandered out of Bluetooth range, so you're not left with gaps in the data when you check back in.
The AirComfort+ is a small Bluetooth sensor, made by iBebot, that measures temperature and humidity and syncs the readings to your phone via the free AirComfort app (iOS and Android). It reads temperature from -25°C to 70°C (accurate to within ±0.5°C at 25°C) and humidity from 0% to 100% (accurate to within ±4.5% at 70% RH), taking a reading at an interval you set — anywhere from every 5 minutes to every 40 minutes — or on demand with a manual refresh.
It's a compact unit at 11.5cm tall and 3.6cm in diameter, weighing 35g, and it runs off a single CR2450 coin cell rated for a minimum of 12 months. Data is stored on the sensor itself for up to 100 days, so even if it's out of Bluetooth range (roughly 10 metres) it keeps logging and dumps the backlog to your phone the next time you're back in range. You can pair up to 32 sensors to one phone at once, which suits anyone running multiple tents or zones.
How it compares
It sits in the same space as general-purpose Bluetooth hygrometers, but with grow-room-specific staying power.
- The Govee H5075 is cheaper and has a longer Bluetooth range (around 60m), but its onboard accuracy is rated ±3% RH and it doesn't match AirComfort's 100-day offline data retention as standard.
- SensorPush's HT.w sensor is factory-calibrated against NIST-traceable references for tighter accuracy (±2% RH), but full remote monitoring needs an additional G1 WiFi gateway sold separately — AirComfort's phone-sync approach is simpler and needs no extra hardware.
- TrolMaster's sensors integrate into a full environmental control ecosystem that can actively drive fans, dehumidifiers and AC — a different tier of product and price entirely if you just need to monitor rather than automate.
For straightforward monitoring rather than automated control, AirComfort+ covers the basics other sensors charge less or more for, without asking you to buy into an ecosystem.
Usage guidance
Set-up takes a couple of minutes once the app's installed.
Placement
Hang it at canopy height, away from direct airflow from an intake or oscillating fan, so it reads the actual conditions your plants are sitting in rather than a draught.
Pairing and logging
Download the free iBebot app, switch on Bluetooth, and the sensor should appear automatically. Set your logging interval (5-40 minutes) based on how closely you want to track swings — shorter intervals give a more detailed graph but use battery slightly faster.
Checking data after time away
Open the app within Bluetooth range and it will pull the full backlog of stored readings, up to 100 days' worth, so you can review what happened while you were out of range.

Who this is for
- Tent growers who want a proper record of overnight temperature/humidity swings
- Anyone managing multiple tents or rooms who needs several sensors on one app
- Growers troubleshooting mould, mildew or VPD issues who need real data, not guesswork
- Buyers who want monitoring only, without paying for a full automated climate system
Our take
This does exactly what a grower monitoring their own tent actually needs — accurate, logged, easy-to-check data — without the cost of a TrolMaster-style automation setup you may never fully use. The offline logging is the real selling point here; it means you're not losing data every time you leave the room.
One we sell a lot of for new growers who want to actually see what's going on in their tent rather than guess. At a price that makes sense.
