iSNATCH HEY GAS WiFi Methane Detector – CH4 Sensor, >70 dB Alarm & Aux Output

The iSNATCH HEY GAS detects the presence of natural gas methane (CH4) using a built-in high-sensitivity sensor. When the measured concentration crosses the alarm threshold, the unit activates an internal buzzer and simultaneously sends push notifications through the Hey Smart app, providing remote awareness even when the user is not in the room.

The device runs on mains power (100–240V) and connects to a 2.4 GHz WiFi network. An auxiliary output at 11–13V / 0.5A allows connection to an external actuator such as a gas solenoid valve for automatic shut-off capability.

Key Features

• Detects natural gas methane (CH4) via built-in high-sensitivity sensor
• Internal buzzer alarm with repeated flashing beep mode
• Push notifications via the Hey Smart app over 2.4 GHz WiFi
• Auxiliary output: 11–13V / 0.5A for external actuator connection
• Mains-powered: 100–240V ~ 50/60Hz
• Alarm sound level: >70 dB at 1 m

Product Benefits

• The high-sensitivity CH4 sensor activates the alarm at a low concentration threshold, providing early warning before gas reaches dangerous levels
• Push notifications to the Hey Smart app alert the user remotely, even when away from the installation area
• The auxiliary 11–13V output enables connection to a motorised gas valve, allowing automatic gas shut-off on alarm
• Mains power means no battery replacement is required, ensuring continuous 24/7 protection
• The >70 dB alarm at 1 m is clearly audible in an open kitchen or utility room
