ESP Easy. 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 ...
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 ...
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 since OpenBSD 3.9 (2006),: §6.1 which has also included an ad ...
DASH7. DASH7 Alliance Protocol ( D7A) is an open-source wireless sensor and actuator network protocol, which operates in the 433 MHz, 868 MHz and 915 MHz unlicensed ISM /SRD band. DASH7 provides multi-year battery life, range of up to 2 km, low latency for connecting with moving things, a very small open-source protocol stack, AES 128-bit ...
An inductive proximity sensor is a non-contact electronic proximity sensor. It is used for positioning and detection of metal objects. The sensing range of an inductive switch is dependent on the type of metal being detected. Ferrous metals, such as iron and steel, allow for a longer sensing range, while nonferrous metals, such as aluminum and ...
In physics and engineering, magnetohydrodynamics ( MHD; also called magneto-fluid dynamics or hydromagnetics) is a model of electrically conducting fluids that treats all interpenetrating particle species together as a single continuous medium.
