I have found a project on wireless temperature sensing using PIC16F877A in this blog https://electronicsfundooo.blogspot.in/ . My question is suppose I have 10 such sensing modules randomly deployed in field. All has same destination address(i.e of base station which is a PC). Will this project work as a Wireless sensor network. If not, will you please give me suggestions to make it work.?
I think the OP is saying all the sensor modules send data back to the same destination which is the xbee master which is connected to the PC RS232 port.
I have not used XBEE Zigbee but I expect it follows the Zigbee standard where each node has a unique address. To make this work you may have to spend some time reading the XBEE Zigbee documentation.
I have built a multi slave temperature sensor network using xbee. Each slave has a unique address that the Master calls, using the AT command set to gather data.
