The Bresser Thermo Hygro Quadro NLX weather station offers the option of measuring temperature and humidity in or around your home at four different locations. This allows for easy monitoring from a single location: is my basement too damp and at risk of mold? Is the temperature in the children's room correct? Is it too hot on the patio? Many more options are available. The weather trend, time, and date are also displayed on the clear color display. The three remote sensors transmit data to the receiving station via 433 MHz radio frequency, while the receiving station simultaneously measures the temperature and humidity, thus providing four measurement results.
