Sensor used is a digital PIR sensor module; This is a basic circuit. It is possible to control Hi-Power sirens (pin D6), and flashers (pin D5) using suitable transistor/mosfet drivers; If you wish to ...

Now that the relay is complete, place the top of the enclosure back on and secure it with the screws it comes with. Step 9: Using a breadboard and the Arduino Uno, build the circuit specified by the ...

simple circuit with an Arduino and PIR motion sensor that can detect movement. An LED will light up when movement is detected. Introducing the PIR Motion Sensor The PIR motion sensor is ideal to ...

This is a simple update to Mr. Hareendran’s PIR Sensor Security Light circuit. It has a shortcoming limits the relay voltage to approximately 3.3V. While this may function with some 5V relays, it will ...

Arduino RCWL 0516 RADAR Sensor Module Circuit Diagram. The following image shows the circuit diagram for interfacing the RCWL0516 module with Arduino. The RCWL0516 uses just one pin to indicate motion ...

Hi there! I hope you are doing great. Today I am sharing the Proteus simulation of my project, in which I have shown the working of three sensors with a single Arduino. These include a PIR sensor ...

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.

Note: Arduino Nano board and Amphenol Humidity and Temperature sensor was purchased from digikey for this project. When we turn on the circuit, soil moisture sensor starts measuring the water level in ...
