â–ŤWhat is IoT communication
The Internet of Things refers to the interconnection of various physical devices, sensors, data storage devices, software, etc. through Internet connection and communication technology, so as to realize the intelligent interconnection between things and between things and people, so as to realize automatic control, modbus ethernet A networked technical system with functions such as information collection and remote monitoring.
Simply put, the Internet of Things is to connect various smart devices to each other through the Internet to realize data sharing and communication, so as to improve production efficiency, reduce costs, and improve user experience.
â–ŤCommunication Types in IoT
The Internet connects people to people, and the Internet of Things connects things to things. The communication type of the Internet of Things can be explained as the connection between human-to-machine (H2M), machine-to-human (M2H), and machine-to-machine (M2M).
1. Human to Machine (H2M)
H2M means that humans provide input to IoT devices, i.e. voice/text/image, etc. IoT devices (sensors and actuators) understand the input, analyze the input and reply to humans through text or visual display, helping humans complete every daily task. It is a combination of software and hardware, including the interaction of humans and machines to perform tasks.
Pros: H2M has a user-friendly interface, can be accessed quickly by following instructions, it is equally quick to respond to any glitches or failures, and features and functions can be customized as needed.
H2M communication applications: facial recognition, biometric attendance system, voice or speech recognition.
2. Machine to Human (M2H)
M2H refers to machine-to-human interaction. Machine-triggered information (text messages/images/voice/signals), independent of any human presence. RS485 to TCP/IP converter This type of communication is most commonly used where machines are instructing humans in everyday life, and it's how humans interact with intelligent systems and other machines to accomplish tasks through the use of tools or devices.
M2H communication applications: fire alarms, traffic lights, fitness bands, health monitoring equipment.
3. Machine to Machine (M2M)
M2M refers to the information exchange and transmission between machines, and the concept of information sharing is achieved through the transmission and link of network and machine equipment communication. Here, communication takes place without human intervention. Machines can be connected to each other by wire or wirelessly. M2M technology integrates data collection, GPS, remote monitoring, communication, information and other technologies to realize the sharing of information between machines, equipment, application processing, background information systems and even operators, and complete the automation of business processes.
Pros: M2M works on cellular networks and is easy to manage. It can be used indoors and outdoors and facilitates the communication of smart objects without human interaction.
