Duane Pearsall developed the first practical home smoke detector called the SmokeGard 700. There are two main types of smoke detectors - ionization and photoelectric - which work by disrupting particle flow or light beams when smoke is detected. Smoke detectors have two key components - a sensor and an alarm - to quickly detect fires and alert occupants. Common applications include commercial and residential fire alarm systems. Future improvements could enhance detection capabilities and interconnectivity.

Smoke detector
This document summarizes different types of fire detection and alarm systems. It describes the main controller as the brain of the system that provides power and monitoring. Smoke detectors are then discussed, including ionization and photoelectric detectors. Ionization detectors use radioactive materials to detect invisible smoke particles, while photoelectric detectors use light scattering to detect visible smoke. Beam detectors can cover large areas by detecting smoke blocking a light beam. Both detector types have advantages and disadvantages, so using both is recommended for maximum fire detection coverage.

FIRE DETECTION AND ELETRICAL POWER ON/OFF CONTROL IN HOME/INDUSTRY USING GSM
The idea behind this project is to use the existing GSM infrastructure. So, all the operations involve the GSM system also. As we send any SMS, it goes through the GSM system. Any sent SMS can be received if we use a SIM card and GSM module. To operate any GSM modem, we have to use the AT commands to operate them. For example, if any SMS arrives the GSM modem sends the serial data in ASCII format. We can read these data if we connect the modem with the serial port of the microcontroller at the baud rate of 9600. As the microcontroller comes to know that a SMS has been arrived, it can sent a proper AT command to read the SMS. The reading of SMS returns the mobile number of sender, the time and much more information. We have to select the SMS part of the message. The starting string of the SMS is used as the password. As the password is matched, then the SMS arrival is assumed to be valid by the microcontroller otherwise, it ignores the SMS. Working of “FIRE DETECTION AND ELETRICAL POWER ON/OFF CONTROL IN HOME/INDUSTRY USING GSM” is very simple.

This document discusses different types of fire alarm detectors, including:
- Optical smoke detectors that detect smoke particles scattering a light beam.
- Ionization smoke detectors that detect changes in air ionization from smoke particles.
- Heat detectors that trigger when one thermistor is exposed to higher temperatures than another reference thermistor.
- Flame detectors that are sensitive to infrared or ultraviolet radiation from flames.
- Linear heat detectors that can detect heat along their entire length to protect large areas.
- Distributed temperature sensing uses fiber optic cables to continuously monitor temperature along their length and pinpoint the location of fires.
Smoke indicator
A smoke detector uses various electronic components like transistors, resistors, LEDs, and a buzzer to detect smoke and alert occupants. It works by using a photo transistor that detects decreases in light intensity caused by smoke particles. When the detected intensity crosses a threshold voltage, the schmitt trigger circuit activates an NPN transistor to power the LED and buzzer, alerting people that smoke has been detected. There are commercial and residential types, with commercial detectors being more expensive and used in public buildings, while residential detectors are lower-cost standalone or interconnected units for homes.

Instrumentation: Liquid and Gas Sensing (Design Conference 2013)
This session focuses on liquid and gas sensing in instrumentation applications.
Liquid Sensing:
Visible light absorption spectroscopy and colorimetry are two fundamental tools used in chemical analysis. Most of these light-based systems use photodiodes as the light sensor, and require similar high input impedance signal chains. This session examines the different components of a photodiode amplifier signal chain, including a programmable gain transimpedance amplifier, a hardware lock-in amplifier, and a Σ-Δ ADC that can measure a sample and reference channel to greatly reduce any measurement error due to variations in intensity of the light source.
Gas Sensing:
Many industrial processes involve toxic compounds, and it is important to know when dangerous concentrations exist. Electrochemical sensors offer several advantages for instruments that detect or measure the concentration of toxic gases. This session will describe a portable toxic gas detector using an electrochemical sensor. The system presented here includes a potentiostat circuit to drive the sensor, as well as a transimpedance amplifier to take the very small output current from the sensor and translate it to a voltage that can take advantage of the full-scale input of an ADC.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
