HC-05 is a Bluetooth SPP (Serial Port Protocol) module that is very easy to use and is designed for transparent wireless signal connection.
Both GSM and this module can be used for IoT applications, but assume that you are building a digital application where multiple nodes are sharing data and are kept at a short distance for communication purposes and if you use GSM module for this application, the cost of the product increases and it also affects the complexity of the project, the remedy on this issue is the use of the short-distance communication modules such as HC-05, Zigbee.
