An unnoticed gas leakage can cause a huge danger. The HEIMAN Gas Sensor (Propane) protects you against escaping LPG gases (Propane) by reliably warning you if a defined limit value is exceeded. With its acoustic alarm (75 db of 1m distance) you get warned early to look up the gas leakage or to keep yourself and your loved ones safe. The reliable gas sensor is recommended for the use in kitchens or in the heating cellar. The smart device also functions as a Z-Wave repeater in your Z-Wave network.
