Protect your home and business from natural gas leaks with our Smart 2.4GHz WiFi Gas Detector, designed for reliable methane (CH₄) detection and real-time remote monitoring. Equipped with a high-performance catalytic sensor and compatible with the Tuya Smart APP, this intelligent gas detector immediately sends alarm notifications to your smartphone whenever a gas leak is detected, allowing you to respond quickly even when you are away.
Designed specifically for the European market, the WiFi Gas Detector JKD-838W complies with EN50194-1:2009 requirements and is CE certified. Every unit is tested by the official SGS laboratory, ensuring consistent quality, stable performance, and dependable safety protection. It is an excellent solution for OEM brands, distributors, wholesalers, and smart home system integrators.
The detector connects directly to your 2.4GHz WiFi network without requiring additional gateways, making installation simple and convenient.
Compatible with both Tuya Smart and Smart Life applications, users can receive instant gas leak notifications, monitor device status remotely, perform self-checks, and manage home safety from anywhere.
Built with a reliable catalytic gas sensor, the detector continuously monitors methane concentrations and quickly activates an alarm when gas levels exceed 8% LEL (4000 ppm).
When a gas leak is detected, the detector activates both a high-intensity sound alarm of ≥85dB at 1 meter and a bright LED warning, ensuring occupants are alerted immediately.
Manufactured according to EN50194-1:2009, the detector carries CE certification and has been tested by SGS, providing confidence for European importers and distributors.
The high-quality catalytic sensor offers a maximum service life of 5 years, ensuring long-term stability with minimal maintenance.
Powered by AC 100–240V, the detector plugs directly into a wall outlet, making installation quick without complicated wiring.

This machine has been calibrated before leaving the factory. You only need to clean the housing of the detector frequently during use to ensure that the hole in the front of the detector is not blocked by dirt or dust .
Basically, no other maintenance is required. When cleaning the detector housing, please use a clean soft brush or dry flannel to wipe, do not use detergent, bleaching powder or polish.
During the working process of the detector, a self-checking test is carried out every minute.
Under normal use, the detector can operate for 5 years. When the detector sends out an end-of-life signal (the buzzer beeps once every minute), the detector must be replaced. If the detector reaches the end of its life, please follow local regulations for disposal.
This product is designed for indoor use only. Please avoid the detector from being exposed to rain or moisture, and avoid dropping the detector. Do not knock, open or modify the detector, otherwise it may cause the product to malfunction.
Covering the detector, improper use or maintenance may reduce or lose the detection function.
