It has a wide range of applications. It is suitable for indoor planting, used in conjunction with plant grow lights to monitor light intensity, and can also be used for measuring natural light outdoors. In greenhouse cultivation and agricultural production, growers and researchers can use it to measure the amount of effective light received by the plant canopy at different heights, so as to optimize light conditions and promote plant growth.
In terms of appearance and operation, it is usually compact in size and equipped with a remote sensor. The operation buttons are simple, such as "POWER" (power switch), "HOLD" (hold data), "MODE" (mode switch), etc., which makes it convenient for users to quickly start measuring and recording data.
