Soil Moisture Sensor Pro Mini
What is this ?
It's the same project than this but without smd components.
I think it's a good node for the beginers ;)
The CR123A is replaced by 2xAAA batteries.
You can order the pcb here : https://PCBs.io/share/z5YOZ

I have put 3 leds on this project :
- one connected on SCK for see the same thing than an arduino pro mini
- one for see when the node is initialised and when is goes in a sleep mode
- one alert you when the battery is low and when the moisture is < xx%
Features?
- Send Soil moisture mesure every hours
- Send Battery Level every hours if the value has changed
- Send Battery voltage every hours if the percentage has changed
Compatibilies ?
- Mysensors Library 2.0.0
- PCBs v1.1.x compatibles with SoilMoisture_Sensor_Pro_Mini_v1.1.x Sketchs
Logs PCB :
V1.1
- 21/02/2017 = Fabrication V1.1 by PCBs.io => Awaiting Panelization
- 27/02/2017 = Fabrication V1.1 by PCBs.io => In Fabrication
- 08/03/2017 = Fabrication V1.1 by PCBs.io => Shipped
- 15/03/2017 = Fabrication V1.1 by PCBs.io => Received
- 15/03/2017 = Assembly and Test => OK
Logs Sketch:
V1.1.2
- Add default values
- Do not send moisture to the controler if she didn't change more than 1%
- Change Low Fuse example
V1.1.3 - In progress
- Fixed "Do not send moisture to the controler if she didn't change more than 1%"
- Added possibility to blink the "info" led when insufficient moisture
- Added possibility to blink the "warning" led when insufficient battery
- Added possibility to use this node without controler (need mysensors >= 2.1.0)
- Disable smartsleep when not OTA used (increase battery life)
