Nowadays, the epidemic is raging and prices are rising wildly. The shortage of "chips" has been alleviated. After all, the current chips are "cabbage" price. In some areas with severe epidemics, an ordinary cabbage can be bought for dozens of yuan, or even There is a situation where vegetables are hard to find. Sales of household soilless cultivation equipment continue to rise, and household soilless cultivation is becoming increasingly popular. The intelligent soilless cultivation system allows users to easily grow their favorite green and healthy vegetables at home, even out of season.

Project configuration:

Main control chip: R7FA2E1A72DFL32

Power supply: typeC+2.54 terminal block

Control: 3 touch buttons + reset + download + relay + 2 PWM outputs

DAC adjustment: 10K adjustable resistor

Debugging: serial port debugging + JLink debugging

Lead out: 8 GPIOs

The main control light panel uses an aluminum substrate with better fan heat, which can quickly fan heat, reduce the temperature of the lamp beads, and extend the life.

12 Hongli photoelectric ceramic substrate plant growth lights solve the problem of insufficient natural light and give plants just the right amount of light.

Red light mode
with a wavelength around 740nm helps plants carry out photosynthesis and promotes plant flowering, color development and fruiting. The red light mode imitates the red light band of sunlight, which is helpful for seed formation, early flowering, early fruiting, and fruit color development.

Blue light mode
Blue light with a wavelength around 450nm can promote the germination of plants. The blue light mode imitates the blue light band of sunlight, which helps plant photosynthesis and meets the light needs of plants in their seedling stage.

Mixed light mode
red light promotes plant stem elongation, carbohydrate synthesis, fruit vitamin C and sugar synthesis, and also inhibits plant nitrogen assimilation; blue light is a necessary supplement to the red light quality and is also a necessary light for crop growth. It is beneficial to the synthesis of high oxides, including stomatal control and phototropism of stem extension. The mixed light mode uses red light band and blue light band to achieve normal plant growth.

Adjustable brightness and on-demand fill-in light.
Under different brightness, the number of photons released by the plant fill-in light will be different. As the brightness increases, the number of photons will also increase. When plants need sufficient light for growth, you can adjust the brightness of the plant fill light through touch buttons or adjustable resistors to fill in light as needed.

Project summary:

1. The voltage of the plant lamp is ignored. The 5V power supply is not bright enough.

2. This plant lamp is difficult to solder. It is recommended to choose Jialichuang SMT.
