I want to make automatic watering for pots at home. Can I benefit from the most cost-effective sets for this?
I would base the decision on what interface you have to control. Are you going to use a standard irrigation controller that is WIFI enabled? Are you going to directly control relays tied to solenoid valves? Both implementations can do what you want but they are very different implementations.there is no financial problem, I am looking for a project set that can be fun. I couldn't decide whether it is more logical to use an Arduino or a raspberry pi.
Soil moisture sensor, For one plant, An Arduino checking the sensor to decide when to turn on the relay that opens the valve. Use a typical USB power supply to power it.Yes, it could be wifi. I thought it would be enough to use a humidity sensor with just a microcontroller.
I only used WIFI as an interface standard that will impact the choice of controller. A single WIFI enabled irrigation controller would not overtax home WIFI.I would not recommend WiFi for home automation communication. Most home routers, like Asus, are only capable of handling about 30 devices. Asus routers will not alert you when they are overloaded, they just bog down and send data erratically.
