The PH-WRQ Wireless Gas Detector is a cutting-edge safety device engineered to protect homes, kitchens, and commercial spaces from the silent yet deadly threat of gas leaks. Designed with advanced 433MHz wireless technology, this wireless gas detector delivers seamless, cable-free communication between the sensor and the host unit — making installation effortless and coverage expansive.
At the core of the PH-WRQ wireless gas detector lies a highly intelligent heartbeat function — a feature that sets it apart from conventional safety devices. The sensor automatically transmits a status signal to the host every 2 hours, confirming that the device is functioning correctly.

The PH-WRQ is specifically calibrated to detect CH4 (methane) — one of the most common and combustible gases used in residential cooking and industrial applications. The high-sensitivity sensor reacts swiftly to even trace concentrations of methane, triggering immediate alerts before a dangerous accumulation can form. Whether installed in a home kitchen, restaurant, factory floor, or utility room, this wireless gas detector delivers consistent and dependable protection.
Powering the device is simple and universally compatible. The PH-WRQ wireless gas detector operates on a wide AC 110–240V input range at a low current draw of just 10–20mA, making it suitable for Bangladeshi standard electrical systems as well as international installations. Its low power consumption reduces operational costs while ensuring the detector remains always-on and always-ready.
Real-time monitoring is available right from your smartphone. Once connected, the wireless gas detector syncs with a dedicated mobile app, allowing you to view live device status, receive push notifications for alarms, and track historical alert logs — all remotely. This smart connectivity transforms a simple gas alarm into a comprehensive home safety system you can monitor from anywhere in the world.
