Another sensor suitable for our project is the Infrared Proximity Sensor. This sensor gives logic high (H) output when an object comes close to the sensor. This sensor only responds to 38 KHz ...

The term passive refers to the fact that PIR devices do not generate or radiate any energy for detection purposes. It works entirely by detecting the energy given off by other objects.The D204B PIR ...

But if you’ve got a project that could benefit from the pairing of a powerful WiFi-enabled microcontroller and a passive infrared (PIR) motion sensor, the Bee Motion created by [Paul Price] is ...

On the hardware side there are no surprises, it consists of a PIR sensor connected to a NodeMCU microcontroller. ... As an Electrical Engineer I see the creative joy in your project.

To create the project, you'll only need a Raspberry Pi, Raspberry Pi-supported camera, PIR motion sensor, LED, and Arduino. The Arduino monitors the motion sensor and controls the LED, while the ...

This easy Raspberry Pi project requires only four hardware parts: the Raspberry Pi, PIR sensor, monitor or TV display, and an appropriate frame to encase the display.

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay, then plug in your fan, and you’re good to go.

The suitability of radar technology for your project depends on a delicate balance of functionality and cost considerations. To help you make an informed decision, let’s delve into the characteristics ...
