To include particle sensor support to CO2 Gadget.
There is a wide list of sensors with which CO2 gadget is already capable of communicating:
| Sensor model | UART | I2C | Detection mode | Status |
|---|---|---|---|---|
| Honeywell HPMA115S0 | Yes | --- | Auto | DEPRECATED |
| Panasonic SN-GCJA5L | Yes | Yes | Auto | STABLE |
| Plantower models | Yes | --- | Auto | STABLE |
| Nova SDS011 | Yes | --- | Auto | STABLE |
| IKEA Vindriktning | Yes | --- | Select | STABLE |
| Sensirion SPS30 | Yes | Yes | Select / Auto | STABLE |
Now we should include them on the CO2 Gadget workflow, so CO2 Gadget is able to (open to change):
- [ ] Configuration (user preferences)
- [ ] Read and process data
- [ ] Include in integrations as (REST endpoints, MQTT, ESPNow, etc)
- [ ] Show on the display
- [ ] Set alarms,
My inmediate plan is to:
- [ ] Implement a basic configuration, where the user can choose if he wants to use particle sensor, which one and where is connected
- [ ] Initialize the sensor and read data from it
- [ ] Display data
Things to short out:
- [ ] Initially only one serial port will be available, so user must choose if using a serial CO2 sensor (no problem with I2C sensors as SCD30 and SCD40/41) or a particle sensor.
- [ ] Displaying data: Many main screens (four?) depending on if there is CO2 and PM sensor or only one of them (and then choose if user select "primary sensor) and it's show bigger on the display and the "secondary" below it, on a small font.
As with most new features, the tasks necessary to implement this are (open to change):
