'''Analog to digital converters (ADC)''' — devices designed to convert input analog signals into digital code.


#Voltage must be within acceptable range.
'''Analog inputs''' — ADC inputs used to measure the voltage applied to them. Analog inputs in automation devices are designed to connect sensors with an [[AnalogSensors_connecting | analog output signal]].
#Ax terminal blocks perform two functions: ADC and low voltage load control. Before measuring voltage, set the corresponding low voltage load control output to the "off" position. For example, if you are connecting to terminal A1, disable A1_OUT in the web interface (section Relays & FETs).
#Connect your source to the terminal. The voltage value will immediately appear in the [[Wired Board Web Interface | web interface]] on the ADCs. The value is also translated into the [[Special:MyLanguage/MQTT|MQTT]] message system.


Also, the value can be obtained in manual mode: [[Special:MyLanguage/Low-level work with ADC|Low-level work with ADC]].

The wb-homa-adc daemon transmits a value to MQTT message queuing to the /devices/wb-adc/controls/Vin topic.
So the value is displayed in the web interface as the Vin channel of the ADC device.

Definitions

Analog to digital converters (ADC) — devices designed to convert input analog signals into digital code.

Analog inputs — ADC inputs used to measure the voltage applied to them. Analog inputs in automation devices are designed to connect sensors with an analog output signal.

Analog inputs in the Wiren Board controller

Wiren Board 6

In the Wiren Board 6 ADC processor chanels are connected to terminals A1-A4. Also, the ADC has an input voltage (after the input diodes) and a voltage at the 5Vout terminal.

Wiren Board 7

In the Wiren Board 7 processor chanels are connected to terminals A1-A3. Voltages at the D1 terminal and at the 5Vout terminal are not measured.

Voltage measurement

Connection and setup

  1. The voltage must be within the acceptable range.
  2. The Ax terminal blocks perform two functions: ADC and low voltage load control. Before measuring voltage, set the corresponding low voltage load control output to the off position. For example, if you are connecting to terminal A1, turn off A1_OUT in web interface (section Relays & FETs).
  3. Connect your source to the Ax terminal. The voltage value will immediately appear in the web interface on the ADCs. The value is also transmitted to the message system MQTT.

Measured voltage display

The wb-homa-adc daemon transmits a value to MQTT message queuing to the /devices/wb-adc/controls/Vin topic. So the value is displayed in the web interface as the Vin channel of the ADC device.
