I received an interesting project where the customer wants to water her lawn with either water from a well or from rainwater collection containers.
Issues to consider are:
- Possible contamination of well water.
- 2 pieces of servo valves cannot be screwed into the 1" to 3/4" reducer. A suitable adapter must be used.
- Multiple transitions from 1" to 3/4 and from 3/4 to 1" negatively affect water flow.
Solutions: Set it so that when rainwater is switched to the well, it will automatically flush. Which means that the garden will be forced to be watered. This will significantly reduce the risk of contamination.
It is very desirable that the water is filtered by filters for solid particles from every side.
It was not possible to use a 1" servo valve on 5V because there is no electricity and he wants to know how many liters of water were used.
I bought 2x Sonoff BSP as seen in the picture and started assembling the distributor from what the customer had.
It will work in such a way that when servo valve 1 opens, servo valve 2 closes and vice versa. Well water will be connected to servo valve 1 and rainwater will be transferred to servo valve 2.
This is explained in more detail in the pictures:
Logic: A open, B closed. Output: well water
Logic: A closed, B open. Output: rainwater
