Light sensor

Light sensor



This is a compact, battery-powered wireless device. The Sensor will help to monitor the level of illumination in the room both at a specific time and over long periods. The mobile application provides statistics of device readings for a day, a week and a month in the form of a convenient graph. It will allow you to evaluate the quality of lighting at your home. Insufficient amount of light has a detrimental effect on your health.
The Sensor can be used to create collaboration scripts with other devices. For example, to automatically turn on the light when illumination level gets lower than the set threshold, or to open the curtains if the dawn is breaking outside.
The device is equipped with a tamper - you will receive a notification in case it is opened or torn off the surface.

A Wi-Fi device supporting Rubetek RF 868 MHz sensors is required to add the Sensor to the mobile app, receive notifications and create scripts.
