Govee Bluetooth Temp & Humidity Sensor
by Govee
The Govee H5075 Bluetooth hygrometer-thermometer features a Swiss-made sensor with ±0.54°F temperature accuracy and ±3%RH humidity accuracy, connecting to a smartphone app via Bluetooth up to 164 feet. The device stores 20 days of on-board data that can be exported as a CSV file through the Govee Home app, which also sends push notifications when readings go outside user-defined ranges. The compact form factor (smaller than a matchbox) fits on any shelf, windowsill, or inside a grow tent or terrarium.

What We Love
- Swiss-made sensor provides ±0.54°F and ±3% RH accuracy
- App notifications alert you when conditions leave safe plant ranges
- 20-day on-device storage with 2-year export history via app
- Tiny form factor fits inside terrariums and grow tents
- Very affordable at under $15 per sensor
Worth Knowing
- Bluetooth only (not WiFi) — requires phone to be in range for live data sync
- Multiple units can occasionally show slightly different readings in the same location
"Knowing the actual temperature and humidity at your plants' level — not just at a wall thermostat — is one of the most impactful data points for diagnosing plant problems. The Govee H5075 is the cost-effective way to collect this data for multiple locations. For orchid growers who need to maintain 50–70% RH, or grow tent users managing VPD (vapor pressure deficit), this sensor pays for itself the first time it prevents a crop failure."
