In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

int greenLed = 3; // Green LED connected to Pin 3 (Safe Mode) int redLed = 4; // Red LED connected to Pin 4 (Intruder Alert) int buzzerPin = 5; // Buzzer connected to Pin 5 (Alarm) int buttonPin = 6; ...

Abstract: Target detection and tracking using optical and radar sensors have many applications in surveillance. As the optical sensor helps to visualize the target and the radar can provide its range ...

An embedded parking assistance prototype designed using the NXP S32K144 microcontroller. The system measures the distance to nearby objects using an ultrasonic sensor and detects motion using a PIR ...

Increased dual sensitivity range, fully adjustable detection, ultra high false alarm immunity, conformally coated electronics. Selectable LED indication, surface mount technology (SMT) and available ...

Researchers at the National Institute of Technology (NIT), Rourkela, have secured a patent for a fully automated system that recognises intruders based on their walking patterns to detect unauthorised ...

Aleph outdoor beams feature sealed optics, an adjustable alarm interrupt, and metered voltage output for alignment purposes. They provide reliable detection even in poor weather conditions, and are ...

Abstract: Accurate sensor fault detection and diagnosis in industrial processes are essential for maintaining system reliability and operational safety. However, under closed-loop control conditions, ...

A team has developed a method for simultaneous detection of multiple disease-causing bacterial species within one hour using a handheld device. Hear the words E. coli or salmonella and food poisoning ...
