Another day, another delivery. This time, a shiny Tenma pH probe has arrived - a delicate looking affair, with the tip sealed into a tiny bottle containing some liquid. This weekend I will hook up the parts to do some initial testing of the sensor.
Plan of action:
- Setup OS on Beaglebone, connect it to my network (and Internet).
- Get MSP430FR5969 started - connect the pH probe to it, and try out some initial code.
- Get Beaglebone talking to the MSP430FR5969, and have some logging going on.
I notice that a humidity/temperature sensor has also arrived, so I will also hook that up and test it.
I am going to get a cheap shelf unit from Ikea which is 2 feet deep, over 2 feet long, and 4 shelves tall. I can sling fluorescent lights under the higher shelves, and plastic growing trays beneath them. Later I will get some heavy duty transparent PVC and fabricate a cover, to complete my cheap greenhouse prototype.
My first actual planting time will be next weekend - for spring season Tomatos, so enough must be ready before then.
