The NodeMCU board has ESP8266 which is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.
This is Zigbee XBee Pro S2C 802.15.4 Module 63mW 3Km+ XBP24CZ7SIT-004 Antenna. The XBee and XBee-PRO ZigBee RF modules provide cost-effective wireless connectivity to electronic devices. They are interoperable with other ZigBee PRO feature set devices, including devices from other vendors.
This Bluetooth XBee Shield V03 Module Wireless Control can achieve a simple two crunodal ZigBee network, achieve wireless communication between Arduino, and allows the Arduino to wireless communicate over a modified ZigBee protocol using the popular XBee module.
Arduino GSM Shield allows an Arduino board to connect to the internet, make/receive voice calls and send/receive SMS messages. The shield uses a radio modem M10 by Quectel. It is possible to communicate with the board using AT commands. The GSM library has a large number of methods for communication with the shield.
MF RC522 is applied to 13.56MHz contactless communication highly integrated chip card reader, is NXP for the "Three Tables" application launch of a low-voltage, low-cost, small size and non-contact card reader chip, smart instrumentation and portable handheld devices developed better choice.
