This article will provide a detailed explanation of how to combine RS485 sensors (powered by DC12V) with data collectors (also powered by DC12V) to efficiently and securely transmit data to servers or cloud platforms using various communication methods such as 3G/4G, Ethernet, and WiFi, and employing protocols like MQTT, HTTP, TCP/IP, UDP, and JOSE for remote monitoring and analysis.

Soil temperature and moisture sensors utilize different technologies to measure the soil environment. tdr and fdr are common technologies. tdr is highly accurate and independent but costly; fdr is fast and cost effective but accuracy is affected by soil type. Sensors such as NBL-S-TM, NBL-TMC (FDR resistive), NBL-S-TMM (FDR capacitive), and NBL-S-THR (TDR resistive) fulfill different needs. Applic···

Installation of ABS tipping bucket rain gauge needs to follow the following steps: selecting a suitable location and preparing the base, fixing the rain gauge and adjusting the level, connecting the signal cable and installing protective facilities. After installation, carry out commissioning tests, check the output signal and record data. For maintenance, pay attention to regular inspection, clea···

best place to place an environmental weather station is an area that takes into account geographic conditions, environmental factors, power supply and communication conditions, security and maintenance needs, and public needs. Following professional guidelines, such as the recommendations of the World Meteorological Organisation (WMO), is an important step in ensuring the effective operation of a ···

The construction of a cloud platform based on the MQTT protocol involves selecting appropriate cloud services, configuring MQTT agents, setting up data loggers, processing stored data, visualizing data, ensuring security monitoring, and regular maintenance and updating, so that sensor data can be efficiently received and processed, and stable operation of IoT applications can be achieved.

There are two types of installations for tipping bucket rain gauges: ground mounting and bracket mounting. Ground mounting is stable, easy to maintain, and suitable for long-term outdoor use, but requires the production of a concrete platform, which is more costly. Bracket installation is flexible, low cost and adaptable, but the stability is relatively poor, and maintenance may be more difficult.···

Multiple RS485 sensors connected to an industrial router for data collection require a series of steps and methods to be followed. The following is a detailed guide:Confirm RS485 sensor interfaces: Ensure that each RS485 sensor has an RS485 interface for data pass-through Ensure that all RS485 sensors and industrial routers have compatible RS485 interfaces, including electrical characteristics and···
