so glad I found this video! i'm researching ways to automate my greenhouse supplemental lighting. I'm currently using an Ambient weather station reading with home assistant controlling the lighting state. but as the light readings are taken outside and in W/m^2 I'm having to guesstimate the accurate loss of light from the glass and structure. I just happen to have an Pi4 sitting around and I just ordered a BH1750. Thanks
Glad the video was helpful! I think BH1750 is a sensor very suitable for a greenhouse. You might be also interested in my other video "Raspberry Pi and Capacitive Soil Moisture Sensors for Gardening". It features the open source hardware board that I designed ANAVI Gardening uHAT with I2C slots for sensors, including for BH1750.
no, not with BH1750 because it is only for measuring ambient light in lux. Other I2C sensors like APDS-9960 has a proximity capabilities (I covered it in another video). I also have a video about detecting distance on Raspberry Pi with HC-SR04 ultrasonic sensor. However, both of these sensors are low-cost and are not capable of measuring microns. Check Mitutoyo calipers and tools.

can you measure distance? sub 10 microns? let's say you have 2 steal plates and you want to measure distance between them
