I welcome you friends and colleagues, I want to offer home-made products such as a thunderstorm sensor, a good thing for those who love hiking and more. It records a thunderstorm in a radius of about 100km. It will allow you

Similar sensors exist as much as RC generators. But it turns out that Arduino can also “teach” to measure the changing sensor capacity - programmatically, an external generator is not required for this.

The author of Instructables under the nickname Luk --- decided to install a lamp with a PIR sensor in her mother's room so that she would not stumble in the dark. Today, there are many ready-made devices for this, but he

The sensor, proposed by Instructables under the nickname AdnanA61, allows you to detect short-wave infrared radiation from sources such as remote controls, fire, incandescent lamps, and the sun. He is not

The author of Instructables under the nickname RaiseStudio talks about the interesting work of the Belgian sculptor Mathieu Zurstrassen - an employee of this studio. This is a head with a mustache and a helmet on which is mounted

In this article, the Wizard will tell us how to independently make an LED lamp with a motion sensor and powered by a solar panel. The big advantage of this lamp is

Strange title, right? What kind of soil moisture sensor is this if it is not waterproof at first? It turns out that such exist. This is a pretty hot commodity in arduino shops. Pay,

I needed an indicator to turn on the engine cooling fan IZH-Planet-5 Temperature sensor which can be adjusted to the response temperature. I took the temperature sensor from GAZ as a basis

Hello, dear readers and residents of our site! In this article, the author of the DIY Creators YouTube channel will tell you how to make a simple stand-alone alarm system that responds to opening a window or

Motion sensors are made in the form of a special electronic device that responds to movements (displacements) in its coverage area and, when a moving object appears in this sector of control,

A pyrometer, which is also a non-contact or remote thermometer, can be considered as the simplest thermal imager with just one pixel. Like a thermal imager, it emits nothing (if it has

The author of Instructables under the nickname Nawielectron proposes to build a working model of the counter of objects, similar to those used on conveyors, conveyors. It contains all the nodes of real counters.

The transmitter is nowhere easier! The transistor used MP42, any low-power low-frequency can be used. voltage 9 v. The microphone is dynamic. Wire 0.2-0.3. Coil on motan on an 8mm ferrite core.

Typically, inexpensive multimeters do not have a temperature measurement function. But this disadvantage can be easily and inexpensively eliminated, while still very quickly. We get a fairly accurate device for
