Configure a digital input for a Connect Sensor on the digital I/O pin

Connect Sensor has one digital I/O pin and you can configure the pin as a digital input.

Note You can also configure the digital I/O pin as a pulse counter. See Configure a pulse counter for a Connect Sensor on the digital I/O pin.

When configured as a digital input, Connect Sensor detects the presence of a voltage level that is either “high” or “low”. Connect Sensor detects voltage levels during sleep cycles and reports them to Digi Axess when prompted by the Wake device on option for the pin, and during the device's scheduled reporting intervals.

To configure the digital I/O pin as a digital input:

  1. Access the web UI for Connect Sensor from the Device Summary page. The Automation Dashboard displays.

  2. Choose Physical I/O > Digital I/O. The Digital I/O page displays.

  3. For Type, select Digital Input.

  4. Configure the pin. Information about the fields is in the table below.

  5. Click Update to save your changes.

Option Description

Input Enabled

Determine when the pin is enabled. Options are:

  • Auto: The pin is enabled only when referenced by an automation input. This is the default.

  • Always: The pin is always enabled.

Internal pullup resistor

Enable or disable the internal pull-up resistor to drive a logic level voltage. For example, use this to drive a logic voltage across a mechanical switch to read the value (open or closed) of the mechanical switch.

Options are:

  • Enabled: When Digital Input is selected, this option is automatically enabled.
  • Disabled: This is the default.

Wake device on

Specifies when you want the Connect Sensor to wake up and push data to Digi Axess.

Options are:

  • None: Data is stored until the Connect Sensor wakes up at the next scheduled time.

  • Rising Edge: When the rising edge is met, the Connect Sensor wakes and sends data.

  • Falling Edge: When the falling edge is met, the Connect Sensor wakes and sends data.

  • Rising and falling edges: When the rising edge or the falling edge is met, the Connect Sensor wakes and sends data.

Power output

Configure the power output. Options are:

  • Disabled: Power does not need to be provided to the sensor. This is the default.

  • Enabled: Power does need to be provided to the sensor.

  • Read Delay Only: When this feature is enabled, you can choose to let the Connect Sensor power the sensor connected to the device, as some sensors need time to level and take the correct reading.

    • 0: The Connect Sensor does not power the sensor. This is the default.

    • n seconds: The Connect Sensor powers the sensor for the number of seconds specified.

Output voltage

Specifies the voltage level output for the power source.

The default is 3.3 Volts.

Read delay

Specifies the time in seconds that the sensor voltage is enabled before Connect Sensor reads its value. This allows the sensor to stabilize to get an accurate reading.

The default is 0.

Note A higher read delay keeps the device powered on longer, which reduces battery life.
