Thermistor. A thermistor is a semiconductor type of resistor whose resistance is strongly dependent on temperature, more so than in standard resistors. The word thermistor is a portmanteau of thermal and resistor . Thermistors are categorized based on their conduction models. Negative-temperature-coefficient (NTC) thermistors have less ...
The Steinhart–Hart equation is a model relating the varying electrical resistance of a semiconductor to its varying temperatures. The equation is. where. is the temperature (in kelvins ), is the resistance at (in ohms), , , and are the Steinhart–Hart coefficients, which are characteristics specific to the bulk semiconductor material over a ...
Integrated circuit sensors. 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 ...
Arduino. Arduino ( / ɑːrˈdwiːnoʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Its hardware products are licensed under a CC BY-SA license, while the software is licensed under the GNU ...
A heat flux sensor is a transducer that generates an electrical signal proportional to the total heat rate applied to the surface of the sensor. The measured heat rate is divided by the surface area of the sensor to determine the heat flux . Silicon encased heat flux sensor for measurements on rugged surfaces.
But BofA analysts expect the "Other 493" to get in on more of the action as second quarter earnings get underway. "Growth is broadening out and so should the market," analysts Ohsung Kwon and ...
Resistance thermometer. Resistance thermometers, also called resistance temperature detectors ( RTDs ), are sensors used to measure temperature. Many RTD elements consist of a length of fine wire wrapped around a heat-resistant ceramic or glass core but other constructions are also used. The RTD wire is a pure material, typically platinum (Pt ...
The Category 1 storm resulted in 2.5 million outages and led to eight deaths in Texas and Louisiana. A power company’s app couldn’t keep up after Hurricane Beryl—so Texans turned to a fast ...
