The Philips Hue Secure Contact Sensor lets you feel safer at home and on the go. Its slim, flexible design is available in black and white. The sensor has an adhesive backing, allowing you to place it almost anywhere, including doors, windows, cabinets, or even safes. Its clever design also lets you position the sensor's magnet on the left, right, or top of the sensor body to ensure the magnet and sensor are always in contact. Adjust your settings in the Hue app to receive motion alerts when the sensor is opened—or trigger a light alarm to deter potential intruders with a simple tap in the Hue app.
