Product information

Description

The TFA 30.3900.02 weather station with indoor/outdoor sensors and wireless transmission provides continuous environmental monitoring for home or office use. The compact base unit displays temperature and humidity readings from both the indoor unit and a wireless outdoor sensor, allowing users to compare conditions at a glance. Wireless transmission ensures flexible sensor placement without running cables, while the clear display keeps key measurements visible for everyday decision-making and comfort management.

Advantages

The device combines indoor and outdoor measurement in a single system with reliable wireless data transfer, making installation and relocation straightforward. A compact, easy-to-read display presents current temperature and humidity values so users can quickly assess comfort levels. The included outdoor sensor is designed for straightforward placement outdoors or near windows, and the base unit supports typical home monitoring needs without complex setup.

Suitable for

Monitoring indoor climate in living rooms, bedrooms and home offices
Tracking outdoor conditions on balconies, patios and near windows
Checking temperature and humidity for plant care and pet environments
Comparing indoor and outdoor conditions to plan ventilation and heating

Key specifications

Measurement types: temperature and relative humidity for indoor and outdoor locations
Transmission: wireless connection between sensor and display unit for flexible placement
Display: clear numerical readout of current values for quick reference
Power: battery-operated components for easy mounting without wiring
Design: compact base unit and separate outdoor sensor suitable for wall mounting or free placement

How to use

Place the base display unit in a central indoor location where readings are easily visible. Install batteries in both the display unit and the outdoor sensor according to the manufacturer instructions, then position the outdoor sensor in a sheltered outdoor spot or near a window at the recommended height to avoid direct sunlight and heavy precipitation. Allow the units a brief period to establish the wireless connection and stabilize readings before relying on values for precise decisions.

Usage recommendations

For accurate measurements, avoid placing the outdoor sensor in direct sunlight, under roof drip lines, or adjacent to heating sources. Check and replace batteries periodically, and position the indoor unit away from radiators and direct airflow from HVAC vents to ensure representative indoor climate readings.
