The Glow Dreaming Perfect Sleep Sensor helps you set the perfect conditions for a great night’s sleep for your baby (and therefore, for you). If you have the Glow Dreaming Perfect Sleep Sensor and want to monitor an additional room beyond the one the Sensor is in, purchase this extra sensor so you can view more rooms in your home while always having the monitor by your side. It is easy to set up and use with each sensor being fully portable. Temperature and humidity are two key factors you can control in any baby's room, and this clever sensor allows you to monitor more than one room from anywhere in the house, ensuring conditions are always conducive for a safe and comfortable sleep. The smart sensor technology will inform you of the best TOG to dress your baby in based on the conditions of each room, not based on the weather outside. Simply place each small remote sensor in the rooms, then keep the monitor wherever you are to check in. When outside the perfect zone you will be notified via the touch screen, then you can adjust the temperature in your baby’s room, or adjust their sleep bag, to help them more effortlessly sleep through the night.

Must buy the Glow Dreaming Sleep Room Sensor for this to work.
