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)
