5.3. Sensor Placement Guidelines

The ITH-20R-O sensors are designed for versatile placement, both indoors and outdoors. Consider the following for optimal performance:

• Indoor Use: Place sensors in areas where temperature and humidity monitoring is critical, such as living rooms, bedrooms, kitchens, bathrooms, or wine cellars.
• Outdoor Use: The sensors are rain-resistant. For outdoor placement, choose a location that is sheltered from direct heavy rain and direct sunlight to ensure accurate readings and prolong device life. Examples include under eaves or in a covered patio area.
• Range: Ensure sensors are within the 300ft/91m wireless range of the WiFi gateway. Obstacles like thick walls can reduce this range.

5.4. Using External Probes (Optional)

The ITH-20R-O sensors are compatible with external temperature/humidity probes (sold separately). These probes can be used for specialized measurements, such as monitoring liquid temperatures or hard-to-reach areas.

• Connect the external probe to the designated port on the side of the ITH-20R-O sensor.
• The sensor will automatically switch to reading data from the external probe.
