Light Research
Questions: did we decide that we’re using artificial light, like the final design will include a portion of light bulbs?
Since, this is a project for individual plants and not large greenhouses, there is no way we can possibly control sunlight from reducing its intensity, however, we can detect levels of intensity and alert the owner if it’s too intense or not intense enough.
We can measure sunlight using LUX, Lux is a standard measure of light intensity. A measurement of 1 lux is equal to the illumination of a one metre square surface that is one metre away from a single candle. This also means 1 lux = 1 lumen per square meter. The more lumens, the brighter the light is in a specific area. Plants need about 7000 to 7500 lumens of light to prosper as indoor plants
We can use three things
Grove sunlight Sensor
https://taylor.callsen.me/the-smart-shoe-a-raspberry-pi-sunlight-sensor/
- Can track UV and IR light that the plant gets sent
issues include: price of raspberry pi 3, wait times to test (shipping from the states),
LDR circuit
https://www.instructables.com/Measuring-Light-Using-Light-Sensor/
- LDR photoresists with Arduino
- Cheap and easy to implement with Arduino
issues include: might not be as accurate at determining which is sunlight and artificial light which can affect plant growth
Adafruit sensor
- https://www.instructables.com/How-to-Measure-LUX-With-Arduino/
- Very precise
- Can detect light ranges from up to 0.1 - 40,000+ Lux on the fly.
- Can separately measure IR, full-spectrum and human visible light
I suggest the Adafruit sensor as it is capable of achieving all our goals with specificity at a low cost
@timiagiri Can you look over the options we have above + your own research for light sensors to decide on what we should use? Thanks
I went with the Adafruit one; I was able to find some in stock on Digikey so that's good!
Can we close this?
Yes! I'll close it now
