Functional Features：

---

The product is developed using a new methane sensor. Paired with it is the GK705Q combustible gas alarm control system, which achieves alarm monitoring function. Combustible gas detectors are used in residential areas and have a significant impact on households using methane gas. They can promptly activate the gas solenoid valve to cut off gas when the ambient gas concentration exceeds the standard.
