    Thanks for organizing.

    With respect to the project, my understanding is that the goal is:

    A cloud-connected set (~6-8) of moisture sensors deployed at the Beacon Hill Food Forest.

    It looks like the capacitive moisture sensor can be read out using i2c.

    It looks to me like some of the littleBits modules can communicate over I2C, unfortunately, it isn't obvious to me whether the cloud module is one of them.

    What is clear is that the cloud module is kind of power hungry, since they say it can only be powered via USB, which might make powering it more challenging.

    I wonder if using some XBees or something else cheaper/less power hungry + something to bridge to the internet would be more practical for a project like this...

      Thanks for attending today's meet up Erik. I really appreciate you following up to let the group know what our intentions are with a cloud connected set of moisture sensors at Beacon Hill Food Forest. Steve Tracy and I will do a site survey in the field and document our findings in a video to share with the group when we reconvene in two weeks on September 7th from noon to 2 p.m...

    The purpose of the circuit is to "chirp" when moisture levels are too low so that you remember to water the plant. Not sure why two output pins are connected to the LED?

    Can't make this meeting (previous commitment) but would be willing to discuss this further at another time.

We just grab a coffee and speak French. Some people have been coming every week for months... it creates a kind of warmth to the group.
