We are starting to look at the possible sensors to add to the device.
We know the temperature sensor we want to use and now we are looking at the SQ-520 PAR sensor from Apogee.
This is an amazing piece of equipment, which will allow us to
- Measure the exact quality of the used LED lights
- Set the intensity of the lights according to the individual plants needs
It is capable of measuring the exact number of photons of the wavelength required for photosynthesis that enter its measurement area.
This sounds like pure science fiction and we will have it in our device!!!
I have contacted the representative of Apogee Instruments to order a sample of the sensor.
We have ordered another set of components for next version of prototype based on WEMOS D1 board.
