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 establishin...

Problems with traditional measurement methods   In the petroleum and petrochemical refined oil circulation industry, most of the measurement of the oil content of the oil tank uses artificial climbing the tank and casting a ruler to measure. Use a metric steel tape measure with a heavy hammer or a scale with a scale to measure, manually record the reading, manually look up the table and convert it, and finally get the oil quantity data. This measurement method not only has high labor intensity, but also has unsafe factors, and cannot guarantee accuracy. In some places, capacitive / diffused silicon pressure level gauges are used for measurement. Due to the serious zero drift of this type of sensor, the measurement deviation is large, and the long-term working stability is poor, which is not welcomed by users. There are also places where isobaric membrane level gauges or mechanical float level gauges are used. However, because the membrane type liquid level gauge is greatly affec...
