Now I have the IO sorted out time to move onto making the firmware come together.

The basic frame work.

Read All   the sensor values  -

• Grow Bed moisture level (Moisture)
• Temperature (Temp)
• Humidity (Humid)
• Water level (WaterLevel)

Send Values to Blynk App.

If Moisture is low - Turn on the Pump for 6 minutes (the length of time it takes to flood the bed)

If Temp is above X level  - Turn on fans

If Humid is below Y level - Turn on mister for 1 minute (this is an arbitrary value and will need tuning)

If WaterLevel is low - Set an Alert on the Blynk App.

Set points to be adjusted by Blynk
