Geevon Wireless Indoor Outdoor Thermometer — 3 Remote Sensors, Backlit LCD & 200ft Range

Geevon’s wireless indoor/outdoor thermometer with three remote sensors displays temperature and humidity across four locations on a large backlit LCD for fast, at-a-glance climate monitoring.

This compact digital hygrometer and thermometer combines a tabletop display with wall-mount capability, three splash-proof remote probes, and 200 ft (60 m) wireless range so you can track conditions in multiple rooms, a greenhouse, or outdoors from one central unit. The unit stores 24-hour max/min records, offers trend arrows and comfort indicators, and supports audible hi/lo alerts plus selectable °C/°F. USB-powered backlight keeps readings visible around the clock when needed.

How accurate are the temperature and humidity readings?

Geevon’s system reports indoor temperatures with ±2°F accuracy and humidity within ±5%, and the outdoor sensor covers a wide temperature span for demanding environments. The base station displays current values alongside the previous 24-hour maximum and minimum so you can see short-term changes and trends.

• Indoor range: 50°F to 140°F (−10°C to 60°C), ±2°F accuracy.
• Outdoor range: −58°F to 158°F (−50°C to 70°C).
• Humidity range: 20%–95%, ±5% accuracy; comfort indicator included.
• 24-hour Max/Min memory with trend arrows for quick interpretation.

Can I place the sensors far from the display, and are they weatherproof?

The three remote sensors communicate on a 433 MHz link with up to about 200 ft (60 m) open-air range, letting you sample conditions in a basement, shed, or garden while the display stays inside. Each remote housing is rated IPX4 splash-proof, which protects against light moisture but not prolonged submersion or direct rain exposure.

• Transmission range: up to 200 ft (60 m) in open space.
• 433 MHz wireless frequency for stable multi-sensor support.
• IPX4 splash-proof remotes—avoid direct sun and heavy rain.
• Supports up to 3 remote sensors plus the main display readings.

What display features and power options does the base unit offer?

The Geevon base has a clear, 5-inch LCD with bold numbers and a USB-powered backlight for continuous visibility. It can sit on a table or hang on a wall, and a simple MEM button toggles between Celsius and Fahrenheit while alert settings let you program high/low audible warnings.
