The circuit is infact a dark activated switch measures the ambient light level and will enable the system only when ambient light level is below a threshold value. Here an LDR (Light Dependent ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

PIR Sensor Module Parts The topmost part of the PIR sensor consists of a lens with concentric grooves carved into the plastic. These are called Fresnel lens. The contours on this plastic helps in ...

Functionality: Arduino code written entirely in C++ without utilizing sleep mode functionality. Controls an LED based on motion detection from a PIR sensor. Turns on the LED for a specific duration ...

The Arduino PIR traffic light simulation is a project that uses a computer or electronic system to model or mimic how a traffic light system works using a PIR (Passive Infrared Sensor) motion sensor ...

Proximity sensing is a common application for intruder alarms, light switches, and other home and industrial automation applications. There are multiple methods of proximity detection used in the ...

We know that measuring the speed of light with an Arduino is possible. It’s just that the implementation is hard. Last month we saw [Udo]’s blinkenlight shield that can be used as a lin… ...

Arduino Motion Sensor – Circuit and Working The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a ...

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 ...

Abstract: In this paper, the Arduino based Intruder Detection System employing Rochelle Salt and Pyro-electric or Passive infrared (PIR) Sensor has been proposed. The proposed system employs Rochelle ...
