Do you know the difference between HTU21DF and HTU21D? at aliexpress i only find the HTU21D. HTU21D-F is from Adafruit and HTU21D an chineese version with less features?
the F refers to filter which this one doesn't have. However code is the same it is just physical filter that makes it different. The one I shown has no "F". I have updated the page where the code is the created image explaining that. See the links.
Hi, I just wrote code to use 2 more of HTU21D sensor the link is in the description and here for you robojax.com/L/?id=274 for I2C, you need to take wires from A4 and A5 and share it with both sensors. I will try to put an image if I can.
my aliexpress HTU21D has a deviation of 2 ° at 24.5 ° C (reports 26.7 ° C) compared to my exact DS18B20 both without activated pullups and with activated ones
we are sorry, today we are migrating to a new system and many links are dead. I've just fixed this link. try it and if you faced problem, try it later today or tomorrow. We do our best to fix this issue.
