Window Sensor 2
The Window Sensor 2 detects the opening and closing of doors and windows as well as vibrations. It can include a temperature sensor and an alarm certifiication making it perfect for security purposes.

Open/close and vibration monitoring for care, security & insurtech

The Window Sensor 2 detects and reports the opening and closing of doors and windows, detects vibration, and monitors temperature. It is also a certified alarm sensor. The features of the window sensor make it a perfect fit for home care, access control, home security, and insurance solutions.

In a home care solution, the Window Sensor 2 can provide insights into a senior’s wellbeing by monitoring activities such as leaving the house. Attached to a fridge or medicine cabinet, the sensor can inform about the resident’s eating and medication habits. Thanks to its vibration feature, the Window Sensor 2 can also be used to monitor sleep patterns or activity inside the house when attached to furniture or appliances.

As a part of a home security system, window sensors can detect and warn about intruders by sending notifications to the residents for unauthorized entry. Furthermore, the vibration feature makes it possible to detect glass breaking, for example shattering a window to intrude a house.

The Window Sensor 2 can be used in various ways to automate the home in IoT solutions. When your customers forget to close the garage door, the upstairs window, or the staircase gate for children, the Window Sensor 2 can be set to remind the customer after a set time and/or at bedtime to close them. Enable customers to connect window sensors to intelligent lights in a smart home solution to automate lighting in their home. The sensor can also be connected to a smart heating or air conditioning system to automatically pause ventilation when the window is opened and optimize energy usage.

The increased awareness of temperature and daily power consumption can help your customers decrease their heating costs.
