The cheapest option for you to consider would be to use Esp8266 modulesTheymodules. They technically cost 1 USD. You can import a bulk (lot) order from aliexpress to make it cheaper. For you command centre you can use a NodeMCU (Esp8266 V12E) costing about 10-12 USD (800 INR).

Program the NodeMCU as a server and the smaller Esp8266s as clients. It is pretty simple and you can choose from many libraries on 'github'. Their GPIOs receive inputs from each sensor and transmit the data over Wi-Fi as there are all connected to a network hosted by your router/modem to your command centre. The

The controllers need a 3V input which is not common, so you need to use level controllers (costs ~2 dollars) step down standard voltages. Once you have received all the data on your server you can process it as desired and program it to give necessary feedback to your sensors.

Cost (excluding senors) for approx 5 sensors = 20 USD.
