PLANET HZS-300, a Z-Wave 4-in-1 Multi Sensor, has four sensors integrated into one device, thus enabling you to monitor the security of doors and windows, humidifiers, lightings, and thermostats of your home at site or remotely. The HZS-300 sends Z-Wave signal to the user when someone is prying a door or window open, or there is a change in humidity, luminosity and temperature. It not only helps to protect homes, offices and other establishments from theft, but also helps to keep humidity, luminosity and temperature in these places within their ideal range.
