@grovento Glad I could help in some way! Hope your sensors behave well for you. :)

Whenever mine arrive I'll be happy to share anything I happen to figure out with them.

@tico Thanks. I've just started to build my small tent (shelf) for shiitake cultivation and gathering information.

@grovento Very cool! Are you building a separate incubation chamber or will shelves/cabinets work well for where you are?

@tico Hi! My apartment has little room to build a chamber. Correspondingly, I just want to test by trial and error how my growth best develops. So I don't need a big thing by now. The idea is to learn everything about shiitake and then build a big chamber.

@grovento   The MhZ19B has low power consumption, even during sampling so it works well on a USB adapter.  The MhZ16 current spikes to 100-120 milliampere when sampling and that is a bit too much for hanging off a USB port ( I've experimented with using tantalum capacitors to minimize the droop ) as the 5v line drops out of regulation. 

For PID control applications, I prefer the MH-Z16 due to probe design and stability.  The MHz-19B tends to drift over time but is just fine if you calibrate it occasionally.

I put in an order for 12 MHz-19B sensors with the vendor, but don't expect to see them until the first week of July.  I'd consider stocking the mhz-16 but the USB adapter would need to be USB-C and those adapters are still expensive right now, but worth looking into for new designs.  At the moment, I use USB-C to USB adapters on my laptop for testing.
