Frogblue frogMultiSense with battery & sensors for temperature, humidity, air pressure and brightness

Multifunctional sensor with replaceable CR2450 battery (45 x 45 x 13 mm) for temperature, humidity, air pressure, and brightness. Window or door opening detection is achieved through magnetic contacts and an acceleration sensor (gyroscope). The battery-operated frogMultiSense measures room temperature, humidity, brightness, and air pressure. Thanks to its battery operation, it can be installed exactly where heating needs to be controlled. For detecting doors and windows, it features two magnetic contacts and an acceleration sensor. Additionally, it can also detect vibrations, such as knocks on the window frame or the glass.
