What is Ppfd meter?
The PPFD Meter uses the phone’s built-in ambient light sensor (ALS) to collect information on each photon that hits the plant canopy. You can also use a Bluetooth sensor. We support seamless integration with UNI-T UT383 BT over Bluetooth Low Energy.
Do lux meters work with LED lights? Lux meters can detect and measure all white light, especially from the sun or incandescent bulb. Lux meters are unable to accurately pick up LED light as LED lights have a higher blue light wavelength. Additionally, lux meters will not be able to tell the luminosity of blue, red or purple LED lights.
Is lux a PPFD?
Both PPFD and Lux are units used to measure the intensity of light. Whereas Lux is universally used to measure and compare the brightness of visible light, PPFD is referring to the amount of light suitable for active photosynthesis of plants.

What does lux stand for?
The lux (symbol: lx) is the SI derived unit of illuminance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface.
Is it good to wake up to sunlight? Waking up to sunlight is a good way to ensure that you will have energy throughout the day. But that’s not all. Because of the sleep/wake cycle, waking up to sunlight in the morning can also help you fall asleep and stay asleep at night. Morning light tells your brain that it is daytime.
Does sunlight help you sleep?
The light/dark cycle of the sun has a powerful effect on the circadian clock, sleep, and alertness. If you understand these effects, you can manipulate light exposure to help yourself sleep better at night and be more alert during the day.
