Soil Moisture Sensor SMD

What is this ?

Simple office plant monitor inspired by @carlierd on the this post.

This is my first SMD project, i hope he'll used by other members ;)

The skech is 2.0.0 Mysensors compatible, i haven't test this sketch with the 2.1.1 version.

You can order the pcb here : https://PCBs.io/share/zjX7M

This node use CR123A battery.

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 Soil_Moisture_Sensor_SMD_v1.1.x sketchs

Logs PCB :

V1.1.2

• 16/02/2017 = Fabrication V1.1.2 by PCBs.io => Awaiting Panelization
• 20/02/2017 = Fabrication V1.1.2 by PCBs.io => In Fabrication
• 27/02/2017 = Fabrication V1.1.2 by PCBs.io => Shipped
• 09/03/2017 = Fabrication V1.1.2 by PCBs.io => Received
• 11/03/2017 = Assembly and Test => Functional Board but some minors issues => see v1.1.2a

V1.1.2a

minors modifications

• Increase Drill battery older CR123
• Modify text "FTDI" by "AVRISP"
• Add text "FTDI"

V1.1.3

moving components

Logs Sketch:

V1.1.1

• Add default values
• Do not send moisture to the controler if she didn't change more than 1%
• Change Low Fuse example

V1.1.2

• 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)

V1.1.3

• Fixed mode without gateway & auto indent code
