  Smart agricultural irrigation is an advanced stage of agricultural production. It integrates emerging Internet, mobile Internet, cloud computing and Internet of Things technologies, and relies on various sensor nodes (flowmeters, pressure transmitters, electromagnetics) deployed at agricultural production sites. Valves, etc. and wireless communication networks realize intelligent sensing, intelligent early warning, intelligent decision-making, intelligent analysis and expert online guidance of agricultural production environment, providing accurate planting, visual management and intelligent decision-making for agricultural production. Smart agricultural irrigation system 1.Wireless transmission The flowmeter measurement data is uploaded to the cloud platform through GPRS, and the cloud platform is displayed in English/English, and the related content is freely defined, and the data analysis and statistics are simultaneously performed, and displayed in a list or a line graph. 2.RS485 bus transmission The flow meter is connected to the computer or PLC system via the RS485 bus.

• Air conditioner temperature sensor faults and solutions

  Air conditioner temperature sensor common fault The air conditioner temperature sensor is a negative temperature coefficient thermistor, referred to as NTC. The air conditioner is used in summer. It is not illuminating. This suddenly does not cool. Is there a problem with the air conditioner? Is the compressor broken? Or the air conditioner is out of order. In fact, you may wish to check the air conditioning temperature sensor from the good start to see if it is malfunctioning and the air conditioner is not working properly. What should I do if I really encounter an air conditioner sensor failure? 1.Room temperature sensor: mainly detects the indoor temperature. When the indoor temperature reaches the set requirement, the internal and external machines are controlled. When the cooling is stopped, the external machine stops, and the internal machine continues to run. 2.Indoor tube temperature sensor: It mainly detects the coil temperature of the indoor evaporator, and prevents cold air, anti-overheat protection and temperature automatic control during heating. 3.Outdoor defrosting temperature sensor: mainly detects the outdoor condenser coil temperature. When the outdoor coil temperature is lower than -6 degrees Celsius for 2 minutes, the internal machine turns into a defrosting state, when the outdoor coil s
