Reproducible films of pure a-ZnTe and a-ZnSe have been prepared using a very high vacuum system and a complete microprocessor-based monitoring system. It is clear that not only must one reproduce every deposition parameter accurately, the anneal history of the sample must also be duplicated. The effect of a single parameter change, as well as the effect of a controlled gas leak which provides known ambients at 10−6 Torr during the sample deposition is reported.

An online environmental monitoring system based on ZigBee wireless sensor network is designed to overcome the drawbacks of the traditional indoor environment monitoring system, such as the difficulty of wiring and the poor flexibility. The ZigBee communication technology, web server technology and GSM communication technology are synthesized, and the indoor temperature and humidity, carbon monoxide, formaldehyde concentration and other environmental information are collected and monitored in real time by various supporting sensors. Users can complete local and remote real-time monitoring of indoor environment by opening Web pages. When a fire or gas leak occurs, users will receive alert messages in time. Experiment show that the system has the advantages of stable operation, simple use and good flexibility, and has high practical value and wide application prospects.

Fire due to  Liquefied Petroleum Gas (LPG) gas leak is one of the disasters that still often occurs in the community. Community ignorance of safety standards in using LPG gas  is one reason. Fires can be prevented if at the time of the LPG gas leak can be detected earlier. Therefore we need a system that can monitor the condition of gas leaks and fires remotely. Internet of things (IoT) technology can be applied to this monitoring system so that information on LPG gas leaks and fires can be monitored remotely. The Internet of Things (IoT) based LPG and Fire leak monitoring system is a concept that utilizes internet connectivity between smartphone devices connected to sensor devices. The devices used to support this system include NodeMCU ESP8266 as a microcontroller and as a liaison to the internet, MQ-6 gas sensors and flame sensors as sensors for detecting gas and fire leaks, buzzers as alarms, and fans as neutralizing gas levels in the room. Data obtained by the sensor will be uploaded to the database via the internet and can be accessed through an android application. The results of the design show that the android application can display notifications when a gas leak or fire occurs. In testing the performance of data transmission, the results show that the highest data transmission delay is 64,61 seconds, and the lowest delay time is 61,56 seconds, the highest throughput value is 747,6 bits/second, and the lowest value is 285,4 bits/second.

This paper presents a case study in the creation and utilization of an Internet of Things (IoT) device. An Arduino-based gas leak detector is utilized for the demonstration of IoT technologies and their advantages. The gas leak detection device focuses on detection of Liquified Petroleum gas. Upon detection of a leak, the device can communicate over the internet using cellular networks, thus helping to alleviate Wi-Fi and ethernet failure issues such as loss of power in a natural disaster. Because of the device’s resilience, it can help ensure the user is notified of the emergency as soon as possible. This automated gas leak monitoring system is reliable and will not be put out of action in a disaster or emergency situation.

ABSTRAKPenggunaan LPG sebagai bahan bakar alternatif pengganti bahan bakar minyak dirasakan lebih efektif dan praktis. Namun kandungan senyawa di dalamnya memiliki efek yang negatif jika menguap di udara bebas. Sistem detektor gas LPG dapat menjadi salah satu solusi untuk mengetahui lebih dini terjadinya kebocoran gas. Implementasi sistem detektor gas LPG pada penelitian ini berupa sistem monitoring nirkabel yang dilengkapi alarm sebagai indikasi jika terjadi kebocoran gas. Sistem terdiri dari bagian Remote Controller dan Master Controller. Remote Controller menggunakan mikrokontroler ATMega16 yang terintegrasi dengan sensor MQ5, LCD dan transceiver RF APC220. Sedangkan Master Controller berupa komputer (PC) yang dapat menampilkan kondisi ruangan yang dideteksi oleh bagian Remote Controller. Sistem berhasil mendeteksi gas LPG dan menampilkan kadar konsentrasinya dalam rentang 200 sampai dengan 1000 ppm. Ketika kadar konsentrasi gas mencapai 5000 ppm, alarm aktif secara otomatis dan memberikan status waspada. Pengiriman data secara nirkabel dengan adanya sejumlah penghalang berhasil dilakukan sampai jarak 200 m.Kata kunci: Sistem Monitoring, Remote Controller, Master Controller, LPG, RF APC220 ABSTRACTThe use of LPG as a fuel alternative to fossil fuels may be more effective and practical. Neverfluless its compound has a negative effect if it evaporates to the air. LPG gas detector system may be one solution to determine the early occurrence of gas leak. The detector system implementation in this study was a wireless monitoring system that had alarm to indicate if there was the gas leak. The system consisted of the Remote Controller and the Master Controller. Remote Controller used ATmega16 microcontroller integrated with MQ5 sensor, LCD and RF transceiver APC220. While the Master Controller in the form of a computer (PC) that could display a room condition was detected by the Remote Controller section. LPG gas system successfully detected and displayed the levels of concentration in 200 up to 1000 range ppm. When the concentration of gas reached 5000 ppm, the alarm activated automatically and provided alert status. The wirelless sending data with a number of barriers was carried out successfully up to a distance of 200 m.Keywords: Monitoring System, Remote Controller, Master Controller, LPG, RF APC220

<span class="fett">Hintergrund und Zielsetzung:</span> PHAR-MON ist ein Monitoring-System, das die auf dem deutschen Markt befindlichen Arzneimittel in ihrer Bedeutung für die Entwicklung von Missbrauch und Abhängigkeit in Suchtberatungsstellen überwacht. </p><p> <span class="fett">Methodik:</span> Klienten ambulanter Beratungsstellen werden im Rahmen der Standarddokumentation zu ihrem Arzneimittelkonsum befragt und Fälle eines abhängigen Konsums, eines schädlichen Gebrauchs oder eines Missbrauchs in PHAR-MON dokumentiert. </p><p> <span class="fett">Ergebnisse:</span> Im Jahr 2006 wurden insgesamt 448 Meldungen von 276 überwiegend alkohol- und drogenabhängigen Klienten in das Monitoring einbezogen. Tranquilizer vom Benzodiazepin-Typ wurden in allen Klientengruppen mit Anteilen zwischen 29,1 % und 35,3 % am häufigsten dokumentiert. An benzodiazepinabhängige Klienten werden zunehmend auch Nicht-Benzodiazepin-Hypnotika verordnet. Bei opioidabhängigen Klienten war im Zeitraum der letzten fünf Jahre ein Anstieg im missbräuchlichen Substitutionsmittelkonsum von 14,9 % auf 33,8 % zu verzeichnen. </p><p> <span class="fett">Schlussfolgerungen:</span> Das Risiko gefährlicher Wechselwirkungen zwischen Arzneimitteln mit Alkohol und Drogen sollte stärker als bisher in die ärztliche Verordnungsentscheidung einbezogen werden.
