What's the difference between wireless Lora and 4G pressure sensor connection ?
How Lora technology apply for pressure/temperature/level transmitter ?
Although Lora is often misused to describe the whole lpwan communication system, strictly speaking, Lora is a proprietary modulation format owned by Semtech. Sx1272 and sx1276 Lora chips use modulation technology called chirp spread spectrum (CSS) to form the physical layer (PHY) of the technology stack.
Lora has two different stacks: lorawan and Symphony link. Symphony link is suitable for industrial and enterprise users who need advanced features. Lorawan is suitable for the mobile network based on lorawan, which develops rapidly in Europe.
Low power wide area network (lpwan) is expected to support billions of devices predicted by the Internet of things. In the whole system, it is composed of many components. The physical (PHY) layer defines the electrical specifications for data transmission at the hardware level. The data link layer is responsible for detecting the change of PHY layer and establishing the protocol of sending data.

How 4G technology apply for pressure/temperature/level transmitter ?
4G technology is widely used in the sensor measurement industry. Based on the mobile network technology, the measurement data can be uploaded in real time through the network cloud platform or server, which is not limited by the region and transmission distance. It can monitor and record the data measured by the sensor in real time by the computer or mobile phone.
