Datasheet
User Manual (PDF)
An indoor-outdoor thermometer is a device designed to measure and display temperature simultaneously for both indoor and outdoor environments. It typically consists of two temperature sensors—one for indoor use and another for outdoor use. The sensors detect temperature variations and display the readings on a single unit.
To ensure accurate outdoor temperature readings, place the outdoor sensor in a shaded, well-ventilated location, away from direct sunlight, rain, or wind. Mounting it on a north-facing wall or under an eave is a common practice. Waterproof sensors for outdoor temperature measurements come with a 4.8ft (1.5m) thin cable for easy installation.
