## Long description

TFA weather station 35.1142 is a battery-powered LCD instrument for monitoring indoor and outdoor temperature and humidity. The main unit displays current values, historical extremes and trend indicators, and receives wireless measurements from up to three remote sensors in addition to the integrated sensor. It supports outdoor temperatures from -40 to 60°C, indoor temperatures from -10 to 60°C and relative humidity readings from 1 to 99%. The device includes an electronic barometer with weather symbols, a radio-controlled clock with date and weekday, and an alarm function. The compact black housing and clear LCD provide readable measurements for home and garden climate control.
Advantages
The unit reports temperature in °C or °F and stores maximum and minimum values so you can track changes over time. Trend arrows and a built-in barometer indicate rising or falling conditions and present a simple weather forecast based on air pressure changes. Wireless sensor transmission at 0.433 GHz allows placement of up to three additional sensors to monitor multiple rooms or outdoor locations. Battery operation (AAA) makes installation flexible without wiring, while the radio-controlled clock and alarm add timekeeping convenience.
