Zucchini requires strong light, so in the actual operation, you can take the morning curtain and put the straw curtain, wipe the membrane without dripping every 3~5 days, remove the grass clippings and dust on the membrane, and hang the back wall of the shed. Membrane, increase the light intensity in the shed; if it encounters continuous rainy or snowy weather, it can spray light film fertilizer, which can help the growing plants absorb light energy, enhance vitality, moisturize the rain, and thrive. Fertilizer management, when the first melon is sitting and growing to 10 cm, the second water can be poured. Later, the zucchini will gradually enter the peak period of the results. In the management of the greenhouse, fertilization and watering should be carried out according to the weather and plant development. Hang the vines, pull a thin steel wire in the north and south at 1.8 meters above each squash, each sling is tied with a sling, the upper sling is tied on the thin steel wire, and the sling of the lower squash must be tied to the knot. After the plant is placed in the melon, it will not tilt to the side. In the melon stage and the expansion stage, Zhuang Gualing is sprayed to increase the water absorption and fertilizer yield and fruit yield and quality, reduce the fruit drop rate, and reduce the incidence of cracked fruit, stiff fruit and deformed fruit. Leave one for each plant when hanging the vines, and wipe off the remaining axillary buds. At the same time, it is necessary to frequently destroy the old leaves that have lost their function and are yellow at the bottom, reducing nutrient consumption. During the growth process, zucchini is prone to many tendrils. To save nutrients, the tendrils should be wiped out early. Disclaimer: Some articles on this website are transferred from the Internet.

The main structures and components of the camera can be listed from the working principle of the camera:
1. LENS
Lens structure, consisting of several lenses, including plastic lens or glass lens
2. Image sensor
It can be divided into two categories:
CCD (charge couple device): charge coupled device
CMOS (complementary metal oxide semiconductor): complementary metal oxide semiconductor
3. Digital signal processing chip (DSP)
There are many DSP manufacturers, such as VIMICRO 301P/L, SONIX 102/120/128, ST (Logitech LOGITECH's DSP provider), SUNPLUS (SUN+focuses on the development of CIF and VGA for single chip, but the image quality is average), PIXART (original phase), PAC207, SQ930C, etc.
4. Power supply
Two working voltages are required inside the camera: 3.3V and 2.5V. The latest process chip can use 1.8V.
Some cameras also use video transmission lines for synchronous power supply without external power lines.
