Wiren Board NETMON-1/en: различия между версиями

Connect the ground of the device to the GND terminal, or connect to a common ground bus.

The sensor output is connected to analog inputs in A1-A7 connectors.  

== Sensors with analog current output ==

There are no special current inputs in the Wiren Board NETMON-1, but you can use a resistor 100-300om, convert the current into voltage and connect as in the previous paragraph.

==== Sensors with resistive output ====

Using an external resistor and a reference voltage, the divider must be assembled to obtain a voltage output (see previous paragraphs).

As a reference you can use the output of +5V from pins 7-8 of connector A1, 1 to 2 of the connector I2.

The sensors are conveniently connected to the "A1" connector, which has two ADC inputs and reference voltages.

=== Analog sensors with external power supply ===

Analog sensors with external power, such as electrochemical sensors series MQ-xxx, humidity sensors HIH-4000, etc. It is also convenient to connect to the connector "A1", which has ADC inputs and reference voltages.

== Sensors/counters with pulse outputs ==

Such devices form a signal by closing two wires that are suitable for them.  

Connect one wire to the "Isolated GND" pin.

Connect the second wire to one of the corresponding contacts (discrete input) of connectors I1,I3,i5,i7,I9.

Some counters have a pulse output on the optocoupler, then the two wires have a polarity - "plus" and "minus".

In this case, the minus is connected to "Isolated GND", "plus" to "discrete input".

=== Network connection of 1-Wire ===

The 1-wire connection uses the I2 connector.

Connect the ground of the network to the contacts GND (7-8@I2, etc.) or common ground bus.

Data line to "1-Wire" contact ( 4@I2).

Power line to contact "5V" (1-2@I2) (internal power supply).

External 1-Wire bus power supplies are allowed.

When using a passive power supply pin of each sensor is connected to the earth wire.

In this case, the bus consists two wires attached, respectively, to '1-Wire "and" GND ".

=== RS-485 network connection ===

See [[RS-485/en|RS-485]].

The Wiren Board NETMON-1 has two RS-485 ports on the "I6" and "I8" connectors.  

Lines A B are connected to terminals A and B respectively.  

== Temperature and humidity sensor ==

Wiren Board NETMON-1 can be equipped with a built-in temperature and humidity sensor. For more information, see [[Sensor SHT1x/en|SHT1x Sensor]].
