Advice wanted on some hardware purchases

[mprogers]

I'm gearing up to teach an IoT class, and had a few questions about components.

1. I understand that the DHT22 doesn't work with the Photon 2, and that I need an SHT30 (?). Is there a library out there that supports that? A search revealed 2, but they don't seem to work with the latest version of DeviceOS.

2. I found this really cool project on Edge Impulse that uses an ADXL 362, but those suckers are $18 apiece, and I'll need 25 of them. I have an HiLetgo, an ADXL345 -- will that work?

3. I am looking for recommendation for Charlieplexing hardware. I've seen the Adafruit offerings, but it promises to provide "lighting effects, without a lot of pin twiddling". For my class, though I want my students to have to do the pin twiddling, can someone recommend "simpler" hardware? I used to use the SparkFun Charlieplexing board, but it's no longer made.

Thanks in advance for any help, I really appreciate the expertise in this community!

Photon 2, and that I need an SHT30 (?).

I have been using a SHT40 device from Adafruit using the library "Adafruit_SHT4x_RK" with the Photon 2 & Device OS 5.6.0

Here is a link:

Hope this helps.

That helps a whole lot, I'm ordering it as we speak!
