## Long description

The TFA 30.3039 digital weather station is a compact indoor/outdoor thermometer and hygrometer designed for continuous climate monitoring at home or in small offices.

The device can be powered by a 1.5 V AA battery and is designed for either wall mounting or desk placement.
Advantages

The instrument supports expansion with up to eight additional wireless transmitters and provides dew point indication, max/min memory with time and date stamps, and a data logger able to store up to 50,000 measured values. Recorded data can be recalled on the display or exported to a PC via USB.

If using external wireless transmitters, pair them with the main unit according to the transmitter instructions; the system supports up to eight transmitters. Set the radio-controlled clock zone if required and configure alarm thresholds for temperature and humidity. Use the built-in controls to view current values, recall max/min records with associated time and date, and review dew point or trend indicators on the display.
Usage recommendations
For consistent readings place the unit at chest height in an interior room, avoid locations near windows, radiators or vents, and allow the sensor at least 30 minutes to stabilise after relocation. Regularly check battery status and, if you plan to use the data logger frequently, back up recorded values to a PC via the USB interface to prevent data loss.
