Home Presence Simulator and Security Control Device

This project allow us to simulate presence and to detect movements in our home. We can configure a network of devices installed in differents rooms of our home all of them controlled by a main device. This project combines these features on a single device (PICTURE 1): It is a presence simulator: the device switchs on and off one light bulb (PICTURE 1) and use an IR transmitter (PICTURE ...

Homemade 6 GHz FMCW radar

Introduction Previously I made a simple frequency-modulated continuous-wave (FMCW) radar that was able to detect distance of a human sized object to 100 m. It worked, but as it was made with minimal budget and there was a lot of room for improvement. FMCW radar working principle If you have read my previous articles you should know how FMCW radar works, but for completeness sake short explanation is given b ...

Arduino 433Mhz RF Wireless Data Transfer

The most practical and cool way of sharing data from 1 Arduino to another is by far using a radio transmitter and receiver. The simplest form of wireless transmission (I could find) is the 433Mhz ASK modules. They come in pairs, a receiver and a transmitter. They are ridiculously cheap, selling at $1 or less a pair!! These modules provide simplex 1 way data transmission, in order to get a 2 way communicatio ...
