The HAOYAO wireless weather station has a black design. The clear colour display shows a wide range of weather information at a glance and is characterised by colour symbols and patterns that make it easy to read. In addition to reliable measurements of indoor and outdoor temperature (-9.9 °C to +50 °C and -40 °C to +70 °C respectively) and humidity (20 % to 95 %), the device offers a precise weather forecast for the next 12 hours based on air pressure measurements, with an impressive accuracy of around 90 %. The weather station is able to monitor indoor climate conditions using high-precision sensors and thus also serves as an alarm clock with snooze function. The station is equipped with an outdoor sensor that offers a range of up to 60 metres and can be connected to up to three channels.
