I got my bolt some time ago but did not get the time to do a real project. But this changed after the enormously hot summer during we needet do irrigate our garden quite a lot.
I did install a Gardena System with microdrippers which is connected to a watertank that collects the water from the roof. Inside the tank we got a waterpump so basically we just need to plug it in and plug it out after an hour.
Now i would like to automate that by beeing able to switch it on via my mobile phone and to minitor the water level with an HC-Sr04 Ultrasonic sensor.
In the community i found a similar project
this describes very good how to control a light bulp ( in my case replaced by the water pump)
what’s stil unclear to me is if its possible to graph the data from the ultrasonic measure and still being able to control the pump manually.
later on it would be nice to program the bolt in the way that the pump turns on each day from X:XX to X:XX and automatically switch it off when either tha tank is empty or it has been running for half an hour - since we often empty the tank because we forget to switch it off.
I guess i got all the material needet:
arduini Uno ( Maker Uno)
relais trigger for arduino
If somebody coult point out some similar examples that woul be really great.
thank in advance
