I am new to IoT. I have been reading articles to connect IoT sesors and updating data to Server.
I want to connect 7 water pump stations ( all in different locations, and distance between each of them 700 mtrs max ) so that they can remotely turned on / off.
Also, I want to manage 30 water flow valves using these devices. Since no WiFi router will offer this wide range, either I have to use multiple GSM modules or Ethernet boards. And both are costly to implement.
Can anyone help me to find out how ESP8266 can be connected to solve this problem?
Arrow marks shows pump stations where as white dots are valves to be managed. There is no clear line of sight path for pump stations or valves. Hope that helps to suggest more.
