What are the values displayed on the display of the greenhouse environmental monitoring system?

Under the windows7 system, people sometimes find that there are black bars on both sides of the center of the screen when playing games with a laptop, how to make the game display in full screen, the following will introduce you to the general solution to the full-screen problem of windows7 games. win+r, open the run window, type regedit enter, this will open the registry, and then, locate to the following location: hkey local machine system controlset001 control graphicsdrivers configuration Right-click on configuration, select Find, and type scaling, Find scaling in the right box, right-click scaling to modify, and change the value to 3 (the original value is 4), this method basically kills the full-screen problem of all games under Windows7.

If the above methods don't work, you can also try: NVIDIA graphics card (N card users) There is a solution to solve the problem of N stuck in Windows 7 (XP is the same) game full screen, the specific steps are as follows: 1. Select "NVIDIA Control Panel" 2. Select "Display" on the left side - change the scale of the flat panel display" 3. Check "Use NVIDIA Zoom Function" In this way, after setting it up, you can try to play the game, and you can basically solve the problem of full screen of the game.

AMD ATI graphics card (A card users) A large number of A card users also encounter the problem of full screen of the game, except for 1024 768 resolution, use any resolution to enter the game full screen mode, there are black bars on both sides of the screen, the solution is as follows: First make sure you are using the latest graphics card driver, go to the graphics card settings center, select the "Configure" option, then click the "Properties" button, change the "Keep aspect ratio" under "Zoom Options" to "Full screen", click the "OK" button, Enter the screen resolution setting interface again, and set the resolution to the normal resolution of your screen (for example, 1366 768 or 1440*900, etc.).

Question 1: Why did my computer screen suddenly shrink into a small screen? Black on both sides?

Question 2: There is also a black screen if my screen does not move for a long time, and the indicator light is also dimmed, but I move and return to the original desktop, so I think, maybe the screen saver is set up, and then I went to see it, and it is clearly set up without protection? Why do you do this every time?

Actually, it's not a big deal, just ask, please solve the top priority, right?

Laser sensors.

Photoelectric sensors.

Photoelectric sensors are the key components to achieve photoelectric conversion in various photoelectric detection systems, and it is a device that converts optical signals (infrared, visible and ultraviolet laser light) into electrical signals.

Photoelectric sensors are sensors that use optoelectronic devices as conversion elements. It can be used to detect non-electric amounts that directly cause changes in the amount of light, such as light intensity, illuminance, radiation temperature measurement, gas composition analysis, etc.; It can also be used to detect other non-electric amounts that can be converted into changes in the amount of light, such as part diameter, surface roughness, strain, displacement, vibration, velocity, acceleration, and the identification of the shape and working state of the object. Photoelectric sensors are non-contact, fast responding, and reliable, so they are widely used in industrial automation devices and robots.

Outdoor weather station equipment can be installed at the entrance of each greenhouse, depending on your needs, each greenhouse has an LED display, or a direct command to finally integrate the data to a large LED screen. The outdoor weather station can collect data such as temperature and humidity, illumination, carbon dioxide concentration, soil temperature and humidity, etc., and upload real-time data to the cloud platform through GPRS 4G, and the real-time data displayed on the large display screen can be displayed on the large display screen with the communication server.

You are talking about the greenhouse environmental monitoring system, I know that the top Internet of things has a special research and development of this greenhouse intelligent control system, which is mainly used for environmental data core and ant and crop information, to guide users to carry out correct cultivation management. It is also a leading position in the same industry, and I hope to help the shed oak to bury you.

Yunfei Technology's greenhouse wet curtain fan, sprinkler irrigation, internal and external shading, top window side windows, heating and supplemental light and other equipment are very convenient to operate and use.

The application of intelligent greenhouse monitoring system in solar greenhouses and plastic greenhouses can only open some basic functions, such as the monitoring of the greenhouse environment, etc., and the automatic control of the environment is relatively poor due to the limitation of the greenhouse itself. Therefore, in order to realize the level of automation, intelligence and mechanization of the intelligent greenhouse monitoring system, the first choice is the glass PC board multi-building greenhouse, which has all the characteristics of a modern large-scale greenhouse, and can be equipped with an intelligent greenhouse monitoring system to automatically control the insulation, light, ventilation and sprinkler irrigation facilities, so as to realize the intelligent regulation and control of the greenhouse environment, and then improve the production efficiency of facility agriculture.
