I want to use this Wireless Sensor Node - Solar Kit for two personal projects :
But I need your advice to see if it could response to my need.
I want to use it to be able to test the sol moisture then activate (or stop) a relay to start (or stop) my garden sprinkler.
Could I then use this moisture sensor and which relay must I use on this same Wireless Sensor Node - Solar Kit ?
I will use the same process to check the Temperature and Humidity in my house and if needed start (or stop) a relay to active a connected fan to this same Wireless Sensor Node - Solar Kit.
Then as you can see there will be some problems. How to solve them ?
A) How to connect one sensor (moisture or temperature/humidity) and one actuator (relay) on the same Wireless Sensor Node - Solar Kit ?
B) By considering I will use a computer fan (5V) which relay must I use to power this fan ?
C) As we may use this Wireless Sensor Node - Solar Kit in external mode I think it could be more interesting to have this Node with the possibility to connect at least two sensors. By example I want it could activate the relay (sprinkler to give water to my garden) but it could be interesting to be able to also have the Temperature and Humidity value at the garden.
Then is it a way to connect a sensor of moisture and a relay and the Temperature+Humidity sensor ?
Sincerely thanks and have a nice day,
