If you're already using an esp32 why not just get a simple ultrasonic sensor and measure flow on an indoor inlet pipe? You may need to know the pressure (probably 1.7 kPa) and temperature but that should be possible to calibrate against your meter readings
Then your project just becomes a simple pipe clamp that can be indoors
This just seems to be detecting if the browser is Firefox. The function is even named isGecko which is Mozilla's browser engine used by Firefox. Edge, IE (Trident) don't return true from isGecko
Unless I'm missing something I don't see where the delay is added
It's not really like they are storing DNA sequences anyways. They use a genotyping array which just reads ~650k single nucleotide polymorphisms (SNPs).
An analogy would be 23andme has a 6.4mil page book of DNA for a single customer but they only know the position and letter of single character on every tenth page. Sure it's enough to identify someone (You can confidently use 50 SNPs to identify these days) but it's not like 23andme was ever storing a whole genome
Otherwise I'd have to install a gui
