Distributed temperature sensing systems (DTS) are optoelectronic devices which measure temperatures by means of optical fibres functioning as linear sensors. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. A high accuracy of temperature determination is achieved over great distances.
ESP Easy is a free and open source MCU firmware for the Internet of things (IoT). [1] and originally developed by the LetsControlIt.com community (formerly known as ESP8266.nu community). It runs on ESP8266 [2] Wi-Fi based MCU (microcontroller unit) platforms for IoT from Espressif Systems. The name "ESP Easy," by default, refers to the ...
The integrated circuit sensor may come in a variety of interfaces — analogue or digital; for digital, these could be Serial Peripheral Interface, SMBus/I 2 C or 1-Wire.. In OpenBSD, many of the I 2 C temperature sensors from the below list have been supported and are accessible through the generalised hardware sensors framework [3] since OpenBSD 3.9 (2006), [4] [5]: §6.1 which has also ...
Although the system is sensitive to both temperature and strain variations these can often be separated as those due to temperature tend to occur at a lower frequency range than strain. Unlike other distributed fiber techniques such as those based on Brillouin or Raman scatter, distributed acoustic sensing is only able to detect changes in ...
The silicon bandgap temperature sensor is an extremely common form of temperature sensor (thermometer) used in electronic equipment. Its main advantage is that it can be included in a silicon integrated circuit at very low cost.
The file format specifications and C source code for a library to read and write GSF files are available from Leidos, [1] who maintain both the format specification and the source code. [3] The GSF library source code is published under the GNU Lesser General Public License, version 2.1. [3]
ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth.The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, an Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise ...
Distributed fiber-optic sensing technology can be used for leak detection through DAS and DTS. [26] AP Sensing has a regional office in Bahrain, and operates throughout the Middle East. [27] Their Distributed Fibre Optic Sensing is designed to monitor pipeline leaks, and is used by the Kuwait Oil Company and the Abu Dhabi National Oil Company.
