Definition and purpose of the sensor | |||
The wireless angle sensor with autonomous power supply '''DU-BLE''' of the ESCORT trademark (hereinafter referred to as the measuring device, product, angle sensor, DU-BLE) is designed to measure the angular position of deflecting parts of various machines and mechanisms relative to the Earth's gravitational field, determine the direction of rotation (in the corresponding modes) and transmit this data via a radio channel at a frequency of 2.4 GHz. | |||
The measuring device (sensor) "DU-BLE" is used in automotive equipment and other objects where angle measurement is required. | |||
DU-BLE | DU-BLE is a completely wireless sensor with autonomous power supply. Sensor data is transmitted in the form of Bluetooth packets in '''Advertising''' mode; the frequency of data sending is every 3 seconds. | ||
More detailed technical specifications are presented in [https://www.fmeter.ru/download/_ftp/eng/datchik-ugla-naklona/eskort-du-ble/Escort%20DU-BLE%20datasheet.pdf?v=071220114144 the device's data sheet.] | |||

''' | '''Serial Number''' - a code consisting of a series of letters or numbers assigned to a product (sensor). | ||
''' | '''Sensor Name''' - sensor designation among BLE devices, consisting of the first two letters of the sensor model and the last 6 values of the '''serial number''', for example, DU_100100 | ||
'''MAC | '''MAC Address''' - a unique identifier assigned to each unit of active equipment. It is used to identify devices in the network. | ||
''' | '''Data Packet''' - a set of values transmitted by a device equipped with a Bluetooth transmitter, the structure of which is specified by the data transfer protocol. | ||
''' | '''Data Transfer Protocol''' - a set of specific rules or agreements of the logical level interface that determines the exchange of data between different programs or devices. In the case of the DU-BLE sensor, the Escort BLE protocol is used to transfer data packets. | ||
''' | '''Advertising Mode''' - a data transfer mode in which the device “distributes” data packets at a certain frequency, regardless of the presence of a device receiving the data. | ||
''' | '''Connection Mode''' - a data transfer mode in which the transmitter waits for a connection to the receiving device in order to start transmitting data packets. | ||
''' | '''BLE-RS485 base''' - a device that retransmits data transmission and converts it from a Bluetooth packet into a data packet transmitted via the RS-485 interface in accordance with the LLS protocol. | ||
''' | '''BA-BLE base''' - a device that retransmits data transmission and converts it from a Bluetooth packet into a data packet transmitted via the RS-485 and RS-232 interfaces in LLS and MODBUS protocols. | ||
