I wanted to ask if I should use two 10 kohm resistors between the VDD and SDA and between the VDD and SCL, as shown in the sensor datasheet. Or if these resistances are already present in the sensor
I am trying to use the nano Arduino micro-controller to interface with the sensirion sht85 sensor. My wiring is as follows:sensor pin 1 => D5 (which is the scl) according to the arduino diagramsensor pin 2 => 5Vsensor pin 3 => GRNDsensor pin 4=> D4 (which is the sda)
The pull-up resistors are not on the sensors board. But as the Wire library activates the internal pull-ups you can ommit the pull-ups if you use short wires (< 10cm).On the Nano SDA/SCL is on A4/A5 and not D4/D5.
If I add a resistor from the 5V to the SDA and SCL wire this should work?
Any suggestions as what might now be the issue?
