CraftBeerPi4 Plugin for SCD30 based CO2 Sensor

Project description

CraftBeerPi4 SCD30 based CO2 Sensor Plugin

Sensors

Plugin will add system a sensor to monitor for instance CO2 monitoring in your fermentation room

Sensor Config

Type

  • CO2: CO2 value in ppm
  • Relative Humidity: Relative humidity in %
  • Temperatur: Temperature

Alarmlimit

  • If a value is entered, an Alarm will be raised, if the sensor value is above the limit.
  • Delete the limit (or don't enter a limit) to disable the alarm.

Alarmtype

  • Single:

    • Alarm is raised once, if Sensor value is above Alarmlimit.
    • Message is shown and can be removed from screen if you click 'ok'.
    • No additional alarm is raised until you reset the alarm or until the sensor value falls below the alarm limit and is rising again above the limit.
    • You can reset the alarm and then a new alarm is raised in single mode. Therefore you need to use the actions menu of your sensor.

    Single Alarm

    • You need to activate Actions for your Sensor in the dashboard (Please see CraftbeerPi Documentation) to activate the Action menu (3 dots)

    3 dots

    • With The action menu, you can reset the sensor alarm:

    Actions

  • Continuous:

    • Notification is send / Alarm is played on every sensor reading if sensor value is above limit
    • Notification is shown on the bottom right and does not persist on the screen.

    Continuous Alarm

Each parameter has to be added as individual sensor.

Multiple Sensors

Installation:

Usage:

  • Configure the update interval of the sensor data in the cbpi global settings. Although shorter cycles ar possible, 30 or 60 seconds should be more than sufficient.

Global Sensor Interval Settings

  • Add Hardware under Sensor and choose SCD30 Sensor as Type and select the parameter you want to monitor.

Hardware requirements:

A datasheet of the sensor can be found here: https://www.sensirion.com/fileadmin/user_upload/customers/sensirion/Dokumente/9.5_CO2/Sensirion_CO2_Sensors_SCD30_Datasheet.pdf

Information on how read from then sensor is documented here: https://cdn.sparkfun.com/assets/d/c/0/7/2/SCD30_Interface_Description.pdf

The sensor is connected via I2C and has the address 0x61. The user just needs to activate I2C in the raspi config and connect the sensor to the I2C bus. The supply voltage (VDD) can be 5V, but the I2C bus has to be at 3.3V
