Many people don’t understand how a motion sensor works. A motion sensor is an electronic device that detects movement within a specified area. It operates by sensing changes in infrared radiation, heat, or sound patterns, triggered when an object, person, or animal enters its coverage zone. ...
Messages are the information that you want to exchange between your devices. It can be a message like a command or data like sensor readings, for example. MQTT – Topics Another important concept is thetopics. Topics are the way you register interest for incoming messages or how you specify ...
Configure a sampling sensor group, including the sampling path and filter criteria. When the configured sampling path meets the filter criteria, the device reports the sampling path to the collector in a timely manner. The following describes how to configure the sampling path and filter criteria...

When somebody walks between the light source and the sensor, the path of the beam is blocked briefly. The sensor registers a drop in light levels and sends a signal to the control box. More advanced security systems include passive infrared (PIR) motion detectors. These sensors "see" the ...
It is often used as a light sensor, light meter, Automatic street light, and in areas where we need to have light sensitivity. LDR is also known as a Light Sensor. LDR are usually available in 5mm, 8mm, 12mm, and 25mm dimensions. Table of Contents How are LDRs Made? LDR Working Pri...
instead of using a retractive switch as the control device, corridor function uses a latching switch, typically a motion sensor (PIR or microwave) or a time switch. This connects or disconnects the additional mains supply which indicates to the driver that is should switch the LEDs on, off ...
How does FMCW Radar Sensor work? Doppler principleis used to determine the object’s motion, speed, and even direction, given the complexity of the radar’s implementation. In the simple case of object detection, the radar transmits a 24 GHz waveform and reflects off an object that is in ...
wiring reduces labor by 70%, and wireless technology makes setup as simple as pushing a button or using your smart device • Monitor, adjust, and manage your system from any smart device to maximize your building's energy savings and occupant comfort How will this solution help my business?
Does it need to "know" the direction or just trigger? You could use an IR sensor, rather than PIR, I think Sharp do a sender and receiver on one small-ish package. I don't know how much metal is on the pooches collar, but you could use a magnetometer possibly. ...
