Our take on the Geevon Indoor Outdoor Thermometer Digital Wireless with 3 Outdoor Sensors

The Geevon is a digital indoor/outdoor thermometer and hygrometer that pairs one LCD base station with three wireless outdoor sensors, so you can watch temperature and humidity in three spots at once. It reads -58 to 158°F with about ±1.8°F accuracy and 20–95% humidity. At $29.99 at Walmart as of November 7, 2026, it is the only new price listed, so there is no recent range to compare against. The 2.4-out-of-5 rating from 23 buyers is a warning sign for a unit this cheap.
