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 ...

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 ...

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… ...

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 ...
