Human body temperature sensed automatic door opening system
This project aims to create an automatic door opening system using a PIR sensor to detect human body temperature. When a person approaches within range of the PIR sensor, it sends a signal to the microcontroller to open the door. The door automatically closes after a fixed time delay if no further movement is detected. This system could also count the number of people entering and exiting an area using an EEPROM to store data even if power fails. The project uses a CD loader to demonstrate an actual door opening and closing when triggered by the PIR sensor detecting a human.

This document compares the characteristics of infrared (IR) proximity sensor, ultrasonic sensor, and laser sensor for distance measurement applications. Each sensor has different operating principles, ranges, angles, and suitability for indoor versus outdoor use. The ultrasonic sensor is found to be most suitable for both indoor and outdoor obstacle detection for applications like quadcopters, as it can measure distances up to 315cm with a 30 degree angle. In contrast, the IR sensor has a shorter maximum range of 30cm and the laser sensor has a narrow angle but can measure up to 1000cm. Experimental results measuring distance, voltage, and light intensity for each sensor confirm the ultrasonic sensor performs best for the given criteria.

senses any obstacle in the path and alarms the user of the obstacle. The device uses a simple principle of
transmitting an ultrasonic signal in the path generated by a wave generator. The signal gets reflected by
the obstacle (if any) in the path. The reflected signal is sensed by a sensor and produces a sound signal in
the form of voice. This voice signal directs the visually impaired person to identify the obstacles in front
of them

Short Range Radar System using Arduino Uno
This document describes the design and implementation of a short range radar system using an Arduino Uno. The system uses an ultrasonic sensor mounted on a servo motor to detect objects within 180 degrees and up to 250cm. The Arduino transmits pulse signals to the ultrasonic sensor and calculates distance based on the echo return time. Distances are sent to MATLAB via UART communication and displayed graphically. The system is able to continuously monitor and detect obstacles in a short range area.

This project aims to create a smart stick for blind people using an Arduino microcontroller. The stick will detect temperature, distance to objects, and light intensity through sensors to provide alerts and help blind users navigate safely. It uses an ultrasonic sensor to detect distance, a light dependent resistor to detect light levels, and a thermistor to detect temperature. When objects are close, it is dark, or temperatures are high, the stick will activate a buzzer and LED to warn the user. The code reads the sensors, makes measurements, and controls the outputs to alert the user based on the sensor readings. The goal is to help blind people avoid accidents and navigate more independently.

This document describes the design and fabrication of a dual ultrasound-based pulse wave radar system with 360-degree vision. Key components include an Arduino Uno microcontroller, two HC-SR04 ultrasonic sensors, an SG-90 servo motor, and a Processing software interface. The system was designed to rotate the ultrasonic sensors using the servo motor to enable 360-degree distance measurement. Programming was done to control the sensors, motor and process sensor data for visual output on the Processing interface. The total cost of components for fabricating the prototype radar system was approximately 2680 Indian rupees.
IRJET- Iot Based Route Assistance for Visually Challenged
This document proposes an IoT-based route assistance system for the visually impaired using ultrasonic sensors and an alcohol sensor. The system attaches three ultrasonic sensors and an alcohol sensor to a cane. The ultrasonic sensors detect obstacles in front, left, and right directions and an Arduino determines the clearest path. A buzzer then provides directional tones to guide the user, avoiding obstacles. An alcohol sensor also warns if the user's alcohol levels are too high for safe walking. The system aims to provide independent mobility and navigation assistance to the visually impaired.

Security System Based on Ultrasonic Sensor Technology
Abstract : In this paper we design and implement a security system with an ultrasonic sensor module to enhance the system’s reliability. The ultrasonic sensor contains a transmitter and a receiver and the module is placed in a rotating motor. It is assumed that an ultrasonic sensor is set in a rotating motor to cover a wide range. The Ultrasonic transmitter periodically emits ultrasonic signals into an open area. A rotating motor is used to allow the sensor to cover whole 360 degrees. If the signal ever hits any physical objects, it will be reflected back and the receiver part of the sensor will then capture it. The microcontroller unit (MCU) will constantly check for the receiver output of the ultrasonic transmitter. If the receiver output is high, the MCU will perform distance analysis of the object from the sensor using the fact that ultrasonic waves travel in air at 340m/s. The time taken for the waves to hit the object and return can be calculated as the time taken for the receiver output to be high after the transmitter has been initiated to send ultrasonic waves. Once the distance is calculated, MCU checks whether the object is within the range threshold specified within the MCU for initiating the alert. If the object is within the range threshold, the MCU initiates a sound alarm and also the global system for mobile communications (GSM) modem to send short message service (SMS) or call to the concerned person. Keywords: GSM Module,Microcontroller unit(MCU),Motor controller driver unit,Ultrasonic sensor(obstacles detection).

The document describes an eye blink monitoring system to prevent accidents due to driver drowsiness. The system uses an infrared sensor to continuously monitor the driver's eye blink rate. If abnormal blinking is detected, such as during drowsiness, an alarm will sound to alert the driver. The system aims to make driving safer by warning drivers before they fall asleep at the wheel.
81485Scanned.pptx
This project creates an ultrasonic-based security alarm system that uses an Arduino, ultrasonic sensor, and buzzer. The buzzer's beeping rate increases as an object gets nearer to the sensor and decreases as the object moves farther away, allowing distance-sensitive detection. The system is built on a breadboard and connects the ultrasonic sensor and buzzer to an Arduino, which is programmed using the Arduino IDE and C/C++ language.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
