 ====== 1-Wire ======
--Wire is a master-slave communication asynchronous bus interface designed formerly by Dallas Semiconductor Corp((https://www.maximintegrated.com/en/products/digital/one-wire.html)). It can transmit data at long distances at the cost of transmission speed. The typical data speed of the 1-Wire interface is about 16.3 kbit/s, and the maximum length is approx. 300m. Name 1-Wire comes from the feature that the data line can directly power elements connected to the bus. A network chain of 1-Wire devices consists of one master device and many slave devices. Such a chain is called a MicroLAN. 1-Wire devices may be a part of a product's circuit board, a single component device such as a temperature probe, or a remote device for monitoring purposes.

Name 1-Wire comes from the feature that the data line can directly power elements connected to the bus.

Such a chain is called a MicroLAN. 1-Wire devices may be a part of a product's circuit board, a single component device such as a temperature probe, or a remote device for monitoring purposes.
 Each 1-Wire device must contain a logic unit to operate on the bus. A dedicated bus converter is needed to connect a 1-wire bus to a PC. The most popular PC/1-Wire converters use a USB plug to connect to the PC and the RJ11 connectors (telephones 6P2C/6P4C modular plugs) for MicroLAN. 1-Wire devices can also be connected directly to the microcontroller boards.

 The physical implementation of the 1-Wire network is based on an open drain master device connected to one or more open drain slaves. One single pull-up resistor for all devices pulls the bus up to 3/5 V and can be used to power the slave devices. 1-Wire communication starts when a master or slave sets the bus to low voltage (connects the pull-up resistor to ground through its output MOSFET).

 === 1-Wire Products ===
-The Dallas/Maxim integrated 1-Wire devices list contains many implementations. The 1-Wire protocol can be quickly implemented into the current IoT boards; most manufacturers share the software libraries, allowing developers to include them in their projects in C, C++, and assembly languages. The 1-Wire sensors (temperature, humidity, pressure, etc.) are factory calibrated and reading the physical measurements follows the International System of Units (SI). 1-Wire products can be grouped as follows:
