The HEIMAN Gas Sensor Zigbee protects against escaping combustible gases like natural gas, coal gas, and others. It emits a 75 dB alarm when gas levels exceed the safety threshold, giving you time to respond. Ideal for kitchens or heating cellars, the sensor also functions as a Zigbee router to extend your smart network. Features: indoor use, low power consumption (<1.5W), Type C power supply, and Zigbee 3.0 compatibility.
