However, when smoke passes through the detector, it bends the light rays so that some hit the light sensor and trigger the alarm. These detectors are best for smoldering fires, which are smaller ...

Product: 22HL-50 Leak Detector Sensor. Description: The 22HL-50 Leak Detector Sensor is engineered to detect liquid leaks in containers, drain pans, false floors, suspended ceilings, and rooms. The ...

Motion sensors are triggered by light changes. As people cross a room, the light shifts, and a motion sensor is triggered; as long as people are moving enough, a motion sensor works fine.

The Motion Sensor requires a Philips Hue Bridge to work, so it's best if you already have an established smart lighting setup ...

They can't trigger smoke detector sensors, but they can cause related problems. If bugs find their way into smoke detector wiring, they could trigger false alarms.

Besides a flashing light alarm, you can also create automations that trigger light scenes when a Hue sensor detects activity. For example, I created an automation that activates a bright light ...

The Aqara model is one of the few water sensors with Apple Home support, while Moen’s sensor disc (which plugs into the Moen detector via a 3.5 mm cable) is extendable by up to 18 feet if you ...

This tachometer (Figure 1) makes do with an uncomplicated detector (phototransistor Q1 with a simple light shield) by following the detector with a high-gain, AC coupled, ... 3 comments on “ Photo ...

One of the most common first sensors people buy for their home is a motion sensor. But in almost all cases, you want a presence sensor instead. The one I'd want is the FP300, which Aqara released ...
