Support for Grove Temp & Humidity I2C sensor #1039

Closed dougseven closed 8 years ago

dougseven commented 8 years ago

I would like to add support for the Grove - Temperature & Humidity Sensor that is included in the Grove Indoor Environment Kit for Intel® Edison. It utilizes a TH02 sensor that can meet measurement needs of general purposes. The C driver for the TH02 is here

rwaldron commented 8 years ago

Looks pretty straight forward!

rwaldron commented 8 years ago

@dougseven I have another user that's reporting issues with the Grove Temp & Humidity sensor; they reported it was a BMP180, but a photograph of their hardware reveals that it's actually this component. I'd like to implement the controller driver for this today.

dougseven commented 8 years ago

I had started looking into it, but haven't had time to work on it. I can look at it more today.

rwaldron commented 8 years ago

Do you mind if I just take over?

dougseven commented 8 years ago

Go for it - happy to help (test, etc.)

rwaldron commented 8 years ago

Excellent—I will call on you to do so :)

rwaldron commented 8 years ago

@dougseven ready for testing—update to latest version

dougseven commented 8 years ago

I'm going to try a different board with the official Yocto image, but using "latest" for johnny-five and edison-io with ubiLinux and Node v4.3.1 gets this:

NOTE: I have previously run a johnny-five app on this board in this configuration.

This OS image is no longer supported. Please upgrade to IoTKit Image with libmraa0 support. https://github.com/intel-iot-devkit/mraa/#installing-on-your-board

Weird, that should only happen if the native bindings are missing 0_o

I set up a new Edison with the official Yocto image. I get some very radical readings using the sample for the TH02 - 80-degree swings (in Celsius). 

  celsius           :  102
  fahrenheit        :  215.6
  kelvin            :  375.15

Other times it would start, read a couple times and then stop reading/outputing to the console:

root@edison:~/iot-labs/basic# node th02.js

That is where it would stop and nothing more would happen. I can stop it (Ctrl+C twice) and run it again, or another simple sample. Not sure what is happening or how to debug it. I tried it with multiple Grove - Temperature&Humidity Sensor (High-Accuracy &Mini).

rwaldron commented 8 years ago

Interesting, I will have a closer look and double check that the initialization operations are correct.

rwaldron commented 8 years ago

Well, I missed the status check :\

rwaldron commented 8 years ago

And of course, I don't have my TH02 with me (I'm in Boston until tomorrow). I have a fix for this, but I just need to double check it against actual hardware, so I should have something by Saturday

dougseven commented 8 years ago

If it's in a branch I can pull then I can test it tonight. No rush though.

rwaldron commented 8 years ago

@dougseven I completely forgot to ping you on this; you can pull and run the last round of work from master
