IoT Device – from Bosch Connected Devices & Solutions GmbH (BCDS)

“BCDS’s first product is a stick-on
door sensor the size of a matchbox, that detects the status of the door, can tell the difference
between movement, knocking and violent intrusion and send reports to the cloud which can in turn send a phone alert to
appropriate persons.”

The HIS110 unit can also be applied to windows and detects conditions such as whether doors and
windows are open, closed or tilted and offers advanced detection of intrusion attempts. This functionality can even be
extended to monitor universal movement detection
