to think about

• moisture sensors may be volatile --> use kalmann filter?

what do we want to measure?

• soil moisture (using capacitance)
• pH
• light (no irrigation during daylight?)
• temperature (no irrigation when it is too hot?)

Shopping list

• [x] moisture sensors
• [x] stepper motor and bracket
• [x] LDR
• [x] guidance rails
• [ ] water pump
• [ ] water hoses
• [ ] valves for left/right positioning
• [ ] ultrasonic sensor

Development history/plan

In this section contains an overview of (future) versions. This includes possible fantasies.

version 0.5

test construction for watering system

version 1.0

first working version. Based on Arduino uno. Standalone, no wireless connection and/or control. no individual moisture sensor checking, just water 2-hourly or something like that.

version 1.5

use moisture sensors to check for each plant

version 2.0

• setup using ESP8266, could be controlled by raspi
• design custom PCB

version 3.0

imagination

version 4.0
