construction and operation of weather stations require technical support in many aspects, including sensor technology, data acquisition and processing technology, data transmission technology, power management technology, remote monitoring and automation technology, data analysis and visualization technology, network security technology and software development and maintenance technology. These te···

importance of soil moisture for spring planting is that it is directly related to the growth and yield of crops. Specifically, if soil moisture is suitable, farmers can sow seeds at the right time to reduce crop growth problems caused by insufficient or excessive moisture; at the same time, water and fertilizer management can be reasonably arranged according to soil moisture to improve the efficie···

automatic weather station is a device used to measure and record meteorological parameters in an automated manner. Automatic weather stations are widely used in agriculture, meteorological science, energy management, transportation and other fields, providing important weather information for decision-making in various industries.

automatic weather station is a device used to measure and record meteorological parameters in an automated manner. It usually includes a variety of sensors for monitoring various meteorological elements in the atmosphere, such as temperature, humidity, barometric pressure, wind speed, wind direction, precipitation, solar radiation and so on. These sensors collect weather data on a regular or real-···

In agricultural production, meteorological changes have a significant impact on the production of food crops. Factors such as temperature, sunshine length, rainfall and wind speed and direction will have a certain impact on the growth and development of crops. Therefore, real-time monitoring of meteorological changes and analysis of meteorological influences on agricultural production are of great···

Leaf wetness sensor is a sensor used to measure moisture on the leaf surface of plants. The Leaf wetness sensor accurately monitors trace water or ice crystal residues through changes in the dielectric constant of the leaf surface, and because it includes temperature detection, it can distinguish between water and ice crystals detected. The appearance mimics the design of a real leaf and therefore···

RS485 sensors have a wide range of applications in industrial automation, building automation, traffic control, environmental monitoring and other fields due to their excellent anti-interference ability and long-distance transmission capability. The following are some typical RS485 sensor application cases:

Wiring Example: RS485 sensor wiring usually includes power, signal and earth wires. Here are the basic wiring steps and precautions: Power Positive > Sensor Power Positive (+)Power negative > Sensor power negative (-);Wire A > Sensor signal wire (transmitter);Wire B > Sensor signal wire (receive side); GND > sensor ground

What is an RS485 type sensor?Sensors with an output of RS485 are sensors that transmit data using the RS485 communication protocol, a differential signal output serial communication protocol that uses a pair of twisted pairs of wires to transmit data, supports long-distance transmission and multi-node connections, and has high immunity to interference and stability.

RS485 interface is a standard interface, in RS485 communication network, it usually adopts the master-slave communication method, i.e., a host (in this case your RTU data collector) with multiple slaves (i.e., your multiple sensors). This type of communication allows one master to communicate with multiple slaves, thus enabling the acquisition of signals from multiple sensors.
