Can internal pullup resistor be used for data-pin instead of having an external resistor as shown in the attached image?
Also, has anyone connected multiple SHT75 with arduino?
I tried to connect three SHT75. With common VCC, GND, and SCK. Three different digital input pins were used for data. However, I have a problem of either only one RH gauge working or none of them work at all. Is it because of common SCK pin? Or is it because I’m trying to get data at once - instead I should apply some delay between reading of three sensors?
Does anyone have experience with multiple SHT75 and arduino? Please share your experience/tips. Any help would be highly appreciated.
