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.

To connect an RS-485 sensor device to a computer, the following is a detailed tutorial that guides you on how to connect an RS-485 device to a computer:I. Prepare tools and materials1. RS-485 to USB adapter: You will need an RS-485 to USB adapter in order to convert the communication line interface of the RS-485 device to a USB interface so that it can be plugged into the USB port of your computer···

choice of whether to use a 0.1mm, 0.2mm or 0.5mm tipping bucket rain gauge needs to be based on specific measurement needs and scenarios. Regardless of which resolution tipping bucket rain gauge is chosen, the needs of the actual application should be considered, including factors such as the required measurement accuracy, time resolution, environmental conditions, and cost. In addition, calibrati···

application of tipping bucket rain gauges in flood monitoring is to provide important hydrological data by accurately recording rainfall and runoff for flood warning, flood analysis and flood management. The following are specific applications of tipping bucket rain gauges in the process of monitoring floods:

RS485 type tipping bucket rain gauge adopts RS485 interface for data communication.RS485 is a serial communication protocol which is suitable for multi-point communication and long-distance transmission, and it can ensure stable communication between the rain gauge and the data acquisition system or other devices.Pulse type tipping bucket rain gauge, on the other hand, records precipitation by gen···
