## Long description

BLOW TH303 is a compact weather station designed to monitor indoor and outdoor temperature and humidity with a wireless external sensor. The main unit displays current readings for both environments, allowing straightforward comparison of indoor and outdoor conditions. Intended for home and small-office environments, this device provides continuous environmental feedback to support everyday decisions about heating, ventilation, and plant care.
Advantages
The BLOW TH303 offers a simple wireless connection between the main unit and the external sensor, enabling placement of the sensor outdoors or in another room without running cables. Its clear display presents temperature and humidity values for quick interpretation. The compact footprint and modest power requirements make it easy to position around the home, on a desk, or mounted near windows. Designed for regular monitoring, the unit provides consistent updates that help identify trends in humidity and temperature over time.
Suitable for
Home climate monitoring (living rooms, bedrooms, basements)
Small offices and workspaces
Monitoring conditions for houseplants and greenhouses
Comparing indoor versus outdoor temperature and humidity
Key specifications
Measurements: temperature and relative humidity for indoor and outdoor locations
Wireless external sensor for remote measurements
Display: main unit shows both indoor and outdoor readings
Compact dimensions suitable for tabletop or wall placement
Power: low-power operation (battery-powered)
How to use
Place the main unit indoors on a flat surface or mount it on a wall within line-of-sight of the external sensor. Install batteries in both the main unit and the wireless sensor following the included instructions. Position the external sensor outdoors or in the remote indoor location where you want to measure conditions, avoiding direct exposure to rain or strong sunlight; a sheltered, ventilated location yields more representative readings. Allow a few minutes for the devices to sync and begin showing current temperature and humidity on the main display.
Usage recommendations
For reliable long-term monitoring, replace batteries before they run flat, keep the external sensor sheltered from direct precipitation and intense sunlight, and place the sensor and main unit away from heat sources or cold drafts to avoid skewed readings.
