The WiFi gas sensor SR-915 is an indoor combustible gas detector designed for CH4 monitoring. It combines local gas leak alarms with 2.4GHz WiFi communication and Tuya App notifications. Users can receive remote alerts and check device status through a connected smartphone.

The SR-915 supports AC100–240V input and has a specified alarm concentration of 6% LEL. It features an audible alarm, a compact ABS housing, and a plug-and-play installation design. The published warm-up time is approximately three minutes.

For distributors, wholesalers, smart-home suppliers, and project contractors, the SR-915 provides a connected option for indoor gas safety applications. SUMRING also supports OEM and ODM discussions for suitable product and packaging requirements.

What Are the Main Features of the SR-915 WiFi Gas Sensor?

1. 2.4GHz WiFi and Tuya App Notifications

The SR-915 WiFi gas sensor supports a 2.4GHz WiFi connection and works with the Tuya App. When the detector is connected and configured correctly, users can receive gas alarm notifications and check device status remotely.

Remote monitoring depends on the network connection, app configuration, and supported device functions. Buyers should confirm the setup process and app requirements before ordering for a project.

2. CH4 Combustible Gas Detection

The SR-915 is specified for combustible gas detection, particularly methane (CH4). Methane is a major component of natural gas, so the detector may be considered for suitable indoor natural gas monitoring applications.

Gas compatibility is important when selecting an alarm. Do not assume that a detector specified for CH4 is suitable for LPG, propane, or every other combustible gas.

3. Specified Alarm Concentration of 6% LEL

The published SR-915 specification lists an alarm concentration of 6% LEL and an error of ±3% LEL. LEL stands for Lower Explosive Limit.

These figures should be checked against the approved technical manual and the requirements of the destination market. Buyers should not treat the stated error as a substitute for an independently verified accuracy specification.

4. Local Audible Warning

The SR-915 provides a local audible alarm with a specified sound pressure of at least 70 dB at a distance of one meter.

A local warning helps alert people near the detector. WiFi and app notifications provide an additional communication channel, but remote alerts should not replace the required local alarm or appropriate emergency procedures.

5. AC100–240V Power Input

The SR-915 supports AC100–240V input. Its published average power consumption is no more than 3W.

This input range may support projects in different power markets, subject to the approved product configuration and local electrical requirements. Confirm the supplied plug type and installation method before placing a bulk order.

6. Simple Indoor Installation

The SR-915 uses a compact ABS housing and a plug-and-play design intended to simplify installation. Its published dimensions are 90 × 90 × 59 mm, excluding the plug from the measurement.

The specified operating temperature is -10°C to +55°C. The published working humidity is up to 95% RH, non-condensing. The product is listed for indoor use and should not be assumed suitable for outdoor or hazardous-area installation.

SR-915 WiFi Gas Sensor Technical Specifications

The table below summarizes the published SR-915 specifications. B2B buyers can use these values for initial product comparison and project planning. Confirm the latest approved datasheet before final technical approval.

Technical Note: The values in this table reflect the published SR-915 product information. Verify the alarm setting, error definition, electrical configuration, and applicable approvals against the latest manufacturer documentation before project acceptance.

How Does the SR-915 WiFi Gas Sensor Work?

The SR-915 combines local gas detection with network communication. The sensing function monitors the target gas, while WiFi supports remote notifications and device status access through the Tuya App.

Step 1: Detect Combustible Gas

Gas in the surrounding air reaches the detector’s sensing element. The detector responds to the target gas specified for this model: CH4 (methane).

Step 2: Evaluate the Gas Signal

The detector processes the sensor signal and checks it against its configured alarm condition. The published SR-915 alarm concentration is 6% LEL, with a listed error of ±3% LEL.

Step 3: Activate the Local Alarm

When the configured alarm condition is reached, the detector activates its local audible warning. The specified alarm sound pressure is at least 70 dB at one meter.

Step 4: Send a Remote Notification

When the detector is connected to a suitable 2.4GHz WiFi network and configured in the Tuya App, supported alarm notifications and device status information can be accessed remotely.

The network connection and the local detection function serve different purposes. Remote notification depends on the network and app setup. Do not assume that remote alerts will be delivered during a network or service interruption.

For general setup information, consult the official Tuya guide to configuring a WiFi device. Follow the SR-915 user manual for the exact pairing procedure.

Where Can the SR-915 Be Used?

The SR-915 WiFi gas sensor is listed for indoor CH4 detection applications. Potential uses include suitable apartments, rental properties, smart homes, kitchens, and selected commercial indoor environments.

Before choosing the product, buyers should confirm the target gas, installation location, WiFi coverage, electrical supply, and local regulatory requirements. The detector should not be treated as an outdoor or hazardous-area device without the necessary approvals.
