On the left the larger chip version, on the right a small version in USB format. The MSP430 is a mixed-signal microcontroller family from Texas Instruments, first introduced on 14 February 1992. [ 1] Built around a 16-bit CPU, the MSP430 was designed for low power consumption, [ 2] embedded applications and low cost.
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 ...
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 Lesser ...
ATmega328 P in 28-pin narrow dual in-line package ( DIP -28N). It is commonly found on Arduino boards. AVR is a family of microcontrollers developed since 1996 by Atmel, acquired by Microchip Technology in 2016. These are modified Harvard architecture 8-bit RISC single-chip microcontrollers.
Accelerometer. An accelerometer is a device that measures the proper acceleration of an object. [ 1] Proper acceleration is the acceleration (the rate of change of velocity) of the object relative to an observer who is in free fall (that is, relative to an inertial frame of reference ). [ 2] Proper acceleration is different from coordinate ...
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 principle of the sensor is that the forward voltage of a silicon diode, which may be the base-emitter junction ...
NodeMCU is an open source firmware for which open source prototyping board designs are available. The name "NodeMCU" combines "node" and "MCU" ( micro-controller unit). [ 8] Strictly speaking, the term "NodeMCU" refers to the firmware rather than the associated development kits. [citation needed]
Rayleigh scattering -based distributed acoustic sensing (DAS) systems use fiber optic cables to provide distributed strain sensing. In DAS, the optical fiber cable becomes the sensing element and measurements are made, and in part processed, using an attached optoelectronic device. Such a system allows acoustic frequency strain signals to be ...
