Sensirion SPS 30

[Romasch]

Hello! Is it planned to support the Sensirion SPS 30 dust sensor on climate firmware?

That sensor is not yet supported in ESPEasy, do you have a plugin written/available for it already, so we can integrate it? It has a lot of similarities with other dust/particle sensors, haven't compared the command/data structures yet.

I don't have a plugin. The library for Arduino is available at the link.

I know about the other sensors. So far, this is the only dust sensor that supports the i2c bus.

You can also use an I2C to serial adapter chip like the SC16IS752
Boards with those can be had from Ali for about 4 euro. (8 euro on Amazon)

These add 2 serial ports to ESPEasy.

I know those work fine with the PMSx003, SenseAir and numerous other plugins that need a serial port.
GPS is probably not the best option for those, since those are really 'chatty' and the serial buffer only has 64 bytes on these.
But it will work.

Hm, the suggested implementation is to use the serial interface, because of less dependency on the advised short wires, and just like most other dust sensors in ESPEasy already have.
Though it could be nice to have a dust sensor on I2C, as they are often combined with Temp/Hum/CO2/VOC etc. sensors that are connected via I2C anyway.

I'll think about it, but no ETA yet. (And also because the sensor is quite costly, would have to buy it just for the sake of development...)

Well that's for sure not the first one....
