Geevon Wireless Indoor Outdoor Thermometer — 3 Remote Sensors, Digital Hygrometer, 200 ft Range

Geevon’s wireless indoor/outdoor thermometer with three remote sensors monitors temperature and humidity across four locations so you can see current readings, 24-hour max/min history, and comfort indicators at a glance.

This compact digital hygrometer system pairs a tabletop/base display with three battery-powered remote sensors to track conditions up to 200 ft (60 m) away. The base station shows real-time indoor and outdoor temperature and humidity, trend arrows, and daily high/low records. Switch between °C and °F, set audible alarms for out-of-range values, and place sensors in rooms, a greenhouse, basement, or other areas where environmental monitoring matters.

How accurate are the temperature and humidity readings?

The Geevon system provides reliable consumer-grade accuracy across a wide measuring range. Temperature readings have about ±1°C (±1.8°F) precision and humidity is accurate to about ±5% RH, suitable for home, cellar, and grow-tent monitoring.

• Indoor temp range: -10°C to 60°C (50°F to 140°F)
• Outdoor temp range: -50°C to 70°C (-58°F to 158°F)
• Humidity range: 20%–95% RH; comfort band indicated on display
• 24-hour max/min logs and trend arrows for quick condition checks

Can I place the sensors far from the main display and still get readings?

Yes — each remote sensor communicates with the base unit via 433 MHz wireless signals. The system supports three sensors plus the base, so you can monitor up to four distinct locations in and around your home.

• Transmission range up to 200 ft (60 m) in open air
• Base displays readings from all paired sensors simultaneously
• Simple installation: wall-mount or tabletop placement
• Battery-powered sensors for flexible positioning (batteries not included)

What alert and history features help me react to environmental changes?

The device stores 24-hour max/min values and can trigger an audible alarm when temperature or humidity crosses your preset thresholds. This helps protect sensitive items and alerts you to sudden fluctuations without constant monitoring.

• Max/Min memory updates every 24 hours and is viewable on demand
• User-defined hi/lo alarms for both temperature and humidity
• Switchable °C/°F display and clear comfort indicator icons
• Audible alarm signals when readings exceed set limits

Where does this thermometer work best inside my home?

The design is versatile enough for many household and hobby uses. Place the base unit in a living area or office and put remotes in a baby room, wine cellar, basement, greenhouse, or garage to track conditions that matter to you.

• Ideal for bedrooms, nurseries, and offices to maintain comfort
• Useful in cellars, wine rooms, or storage to protect valuables
• Practical in grow tents and greenhouses to monitor plant environments
• Wall-mountable or freestanding base plus compact remote sensors

Who is this for: The Geevon wireless thermometer with three remotes is aimed at homeowners, hobby growers, wine and cellar keepers, and families who want an affordable, easy-to-read way to watch temperature and humidity across multiple spots. If you need simple setup, audible alerts, and clear 24-hour history across several rooms or outdoor spots, this kit delivers flexible monitoring without complex wiring or apps.
