Wireless communication: The monitoring module can receive signal feedback from sensors or other devices through wireless communication technologies (such as Wi-Fi, Bluetooth, Zigbee, etc.). ). These wireless communication modules can transmit signals to the controller or central processing unit of the monitoring module for further processing and analysis.
Wired connection: The monitoring module can also receive signal feedback through wired connection (such as Ethernet, RS-485, etc.). ). This method is usually used in application scenarios that require high bandwidth and stable connection, such as video surveillance systems.
