= <big>'''Definition and Purpose of Sokol-DVP and Sokol-BMVD'''</big> =

== <big>'''Sokol-DVP'''</big> ==
The '''Sokol-DVP''' soil moisture and temperature sensor (hereinafter referred to as '''“Sokol-DVP”, “the device”, “DVP”,''' or '''“the DVP sensor”''') is designed to determine the mass fraction of soil moisture (hereinafter referred to as soil humidity) and '''soil temperature.'''  

The '''Sokol-DVP''' sensor is a fiberglass '''(FR4)''' plate in the shape of an elongated trapezoid with a pointed end for easy installation in the ground.

The measuring part of the sensor contains '''capacitive sensing elements''', insulated by two layers of fiberglass. The electronic board is located inside a rectangular casing.

The operating principle for temperature measurement is based on '''the change in resistance depending on soil temperature.'''

More detailed technical characteristics are presented in the  [https://drive.google.com/file/d/1WBmJWBZqSngEo19GLjMTBAyGJz-OC1AD/view technical data sheet of the device]

== '''Sokol-BMVD''' ==
The '''Sokol-BMVD''' wireless external sensor modules (hereinafter referred to as '''“BMVD” or “the device”''') are designed for automatic reading of '''soil temperature, soil moisture, and detection of the presence or absence of moisture on plant leaves''' or other surfaces '''(leaf moisture)'''.

The module receives readings from four independent inputs connected to up to four external sensors and transmits all collected data to the '''Sokol-M1''' weather station via a '''LoRa 433 MHz wireless channel''' during the next communication session.

Up to '''eight BMVD modules''' can be connected to one station.

Each BMVD can connect up to '''four soil moisture/temperature sensors (Sokol-DVP)''' and/or '''one leaf moisture sensor (Sokol-DVL)''', depending on the supplied model.

The communication range between the '''station''' and a '''BMVD module''' can reach '''up to 5 km''' under direct line-of-sight conditions without interference. For best performance, there should be '''no obstacles''' between the antennas of the station and the BMVD. The '''BMVD''' module should be mounted at a certain height '''above the ground.'''

(''Note: Production of the '''Sokol-DVL''' leaf moisture sensor has been stopped.'')

More detailed technical specifications are provided in the documentation (under review).

= <big>'''Connection Methods Between Sokol-DVP and Sokol-M1'''</big> =
The '''Sokol-DVP''' sensor can be connected either directly to the input of the '''Sokol-M1''' station or via the '''Sokol-BMVD''' wireless module. In this case, the '''Sokol-M1''' weather station receives data from the '''Sokol-DVP''' sensors through a '''LoRa 433 MHz wireless channel'''.

== <big>'''Sokol-DVP via Sokol-BMVD'''</big> ==

# The '''Sokol-DVP''' soil moisture and temperature sensors can be connected to the inputs of the '''Sokol-BMVD''' device (inputs '''#1, #2, and #3''' for the old version). Input '''#4''' of the Sokol-BMVD operates in '''analog signal measurement mode''' and is used to connect the '''Sokol-DVL''' leaf moisture sensor. The '''Sokol-DVL''' leaf moisture sensor is currently not in production.
# The '''Sokol-DVP''' soil moisture and temperature sensor can be connected to the inputs of the '''Sokol-BMVD''' device in the '''new version''' (to '''all four inputs'''; connection of the '''Sokol-DVL''' sensor is not supported in this version).

Below are the '''connection diagrams''' for '''Sokol-DVP''' sensors with different versions of the '''Sokol-BMVD''' module:

[[File:SOKOL APP MAC PAGE.jpg|center|frameless]]


Click '''Next'''. After this, the '''station connection setup''' is complete - proceed to the next step.

'''''<u>(Further in the app, images with descriptions and step-by-step synchronization instructions will be provided. A more detailed explanation of synchronization is presented below.)</u>'''''

== <big>'''Sokol-DVP + Sokol-BMVD - Synchronization with Sokol-M1 Station'''</big> ==
The next step is to '''synchronize''' the operation of the station and the BMVD.

After being powered on, the weather station transmits a '''sync packet every 15 seconds''' for a period of '''three hours'''.

For the BMVD to successfully synchronize with the station, the following conditions must be met:

* The weather station must have a '''GPS or GSM connection''' to set the correct time.
* The weather station must be '''transmitting sync packets''' so that the BMVD can '''detect''' it.
[[File:CFG STATE PAGE.png|center|frameless|750x750px]]


There is also an option to activate the '''“BEACON” mode''' directly on the station to start transmitting sync packets for synchronization with the '''BMVD.'''

Once activated, this mode operates '''for 6 hours''', after which it turns off '''automatically.'''

To properly connect the '''BMVD''', follow these steps:

'''- Install the batteries''' in the '''BMVD''' (or connect the battery connector if you are using the '''new BMVD''' version). The '''green LED''' will light up.
[[File:INDICATOR 1 BMVD.jpg|center|frameless|805x805px]]


'''-  Place the weather station outdoors''' and '''reboot''' it by turning the key to the '''OFF''' position for '''2 minutes''', then turning it back to '''ON'''.
[[File:STATION KEY INSERT.png|center|frameless|810x810px]]


'''-''' When the '''red LED''' on the '''BMVD''' starts '''blinking (1)''', '''press and hold the SET button (2)'''. The '''green LED (3)''' will turn off.  After this, the synchronization process can be considered '''successful'''.
[[File:BMVD INDICATOR 2.jpg|center|frameless|804x804px]]
<blockquote>
'''<u>Note that the red LED on the BMVD blinks depending on the signal strength.</u>'''

 '''<u>If the LED blinks three times or fewer, you should move the BMVD closer to the station or raise it higher to improve the connection.</u>'''</blockquote>

== <big>'''Viewing Data from Sokol-DVP + Sokol-BMVD'''</big> ==
After successful synchronization, data packets from the '''BMVD''' will appear together '''with other parameters''' transmitted by the station (e.g., via '''GSM''') in the following format:
