iSpindel DIY continuous hydrometer, for measuring the realitive gravity / density of wort. Meant as an educational project for [https://kwbg.nl KWBG]. We created footprint for the various parts on the PCB. These can be found in the /libs dir in the repo. Furthermore we replaced the reset switch with a reed switch so you can use a magnet to reset the iSpindel without opening the container.
Why Bat43???
It seems to me that the selection of the diode to be a schottky is a critical one here! According to the datasheet, the min. Input Low Voltage must be < 0.25×VIO while the Output Low Voltage is up to 0.1×VIO. Therefore, this leaves 500mV where the BAT43 will drop around 300mV or more. So a regular silicium diode will fail in this setup! Using a BAT43 or better is a requirement so to speak.
