I''ve been collecting things for a while now and I'm set (also probably at $200, although I went to a lot of sales)
- Windows Computer (that was the hardest thing to find, I'm a Mac/UNIX guy)
- TI SDK - so far, so good
Adafruit Sensors
- Two flow meters to experiment with tracking the water used by the system; clamp on ultrasonic doppler flowmeter is probably too expensive, but would be preferable, energy-wise
- Two soil humidity sensors to evaluate if the lawn needs watering
- eTape Liquid level sensor (to read rainwater barrel level so as to cache the water used)
Hardware Stores
- RF watering control solenoid (Clearance item in the Rona mega deals bargain tent, photo below)
- 40 W Coleman solar panel, to power the whole thing (half price sale at Canadian Tire)
- Hoses
App Development
- iOS8 on iPhone 4
- iOS8 XCode
- iPhone 6 (on order) - NFC Proximity Authentication Testing
