Who it fits

Key Specs for This Sensor

Switch Function: Motion Sensor

This device uses Passive Infrared (PIR) technology to detect moving objects. It automatically turns lights on when you enter a room and off when you leave. This removes the need for manual switches. It is ideal for areas like hallways, bathrooms, or closets where you want hands-free control. Compare this to standard wall switches that require physical interaction.

Detection Range: 360 degrees

The sensor covers a full circle around its installation point. This allows it to detect motion from any direction without blind spots. You should install it centrally in the room for best coverage. This is useful for open spaces or rooms where movement occurs in multiple directions. Look for similar wide-angle coverage when shopping for home automation sensors.

Wiring Requirement: Neutral Wire Required

This switch needs a neutral wire in your electrical box to function. Not all older homes have neutral wires available at switch locations. You must verify your wiring before purchase. If your box lacks a neutral wire, this model will not work. Check your existing setup to ensure compatibility with this specific wiring requirement.

Compatible Bulbs: LED, Incandescent, CFL

The sensor works with various light types, including LED, incandescent, and fluorescent bulbs. This flexibility lets you use it with most existing fixtures. You do not need to replace all your bulbs to use this switch. Verify that your specific bulb type is listed in the compatibility chart. This broad support simplifies integration into existing home lighting systems.

Physical Design and Build Specs

According to the listing, the ECOELER YM2511 is finished in white. Its dimensions are 3.97 inches in length, 3.14 inches in width, and 1.37 inches in height. The unit weighs 5.93 ounces. These compact measurements allow it to sit flush against a ceiling without protruding significantly. This low profile helps it blend into high-bay fixtures or standard ceiling mounts where visual clutter is undesirable. The small footprint ensures it does not obstruct the light beam of the fixture it controls.

The device relies on Passive Infrared (PIR) technology for detection. It uses infrared signals to identify moving objects, triggering the light to turn on or off automatically. A bright LED indicator illuminates when motion is detected, providing visual confirmation of activation. This feature helps you verify that the sensor is functioning correctly during installation or testing. The 360-degree detection range covers a 24-foot radius when installed at a height between 5 and 20 feet. This wide angle makes it suitable for open areas like hallways, bathrooms, or closets.

Adjustable settings allow you to fine-tune performance. You can set the time delay from 15 seconds to 30 minutes. Sensitivity ranges from 20 to 100 percent. You can also adjust the light level sensing threshold. These controls let you customize how the sensor responds to different room sizes and lighting conditions. The unit requires a neutral wire for installation. It supports LED, incandescent, and fluorescent bulbs, ensuring broad compatibility with existing lighting systems.

Setup, Wiring, And Daily Settings

You must ensure your electrical box includes a neutral wire before installing this ECOELER YM2511 sensor. The listing specifies that a neutral wire is required for operation. Without this connection, the device will not function. You will mount the unit to a ceiling or high-bay fixture using the provided hardware. The compact dimensions of 3.97 inches in length and 3.14 inches in width allow for a discreet fit on most standard ceilings. Once wired, you can adjust the operational parameters to suit your space. The sensor features adjustable time delays ranging from 15 seconds to 30 minutes. This lets you control how long lights stay on after you leave. You can also set the sensitivity between 20% and 100%. This helps prevent false triggers from small pets or drafts. The light level sensing allows you to set a threshold so the sensor only activates when the room is dark. Daily use is passive. The PIR technology detects infrared signals from moving objects. When you enter the 24-foot detection range, the light turns on. It turns off automatically when the room is empty for the set duration. The unit works with LED, incandescent, CFL, and fluorescent bulbs. It supports both magnetic and electronic low-voltage transformers. A bright LED indicator shows when motion is detected. This visual cue helps you verify the sensor is active during the initial setup phase.

Before You Buy This Sensor

This ECOELER YM2511 is a dedicated motion sensor, not a smart thermostat or hub. It does not connect to Wi-Fi or your home network. You will need to pair it with compatible lighting fixtures rather than a central control system. Check your bulb types carefully. The listing confirms support for LED, incandescent, CFL, and various fluorescent ballasts. Ensure your existing wiring includes a neutral wire, as this is a strict requirement. Without it, the unit will not power on. You should also verify ceiling height, as optimal detection occurs between five and twenty feet. The adjustable sensitivity and time delay settings allow you to fine-tune performance for specific spaces like closets or hallways. This device fits into a smart home as an automated switch layer. It works alongside your thermostat by managing lighting efficiency, reducing energy waste in unoccupied rooms. It does not replace climate control but complements it by handling illumination automatically based on presence.

Check before you buy

• Confirm your electrical box has a neutral wire connection.
• Verify your light bulbs match the compatible types listed.
• Ensure ceiling height is between five and twenty feet.
• Check if you need a 360-degree or directional sensor.
