Now create a function to calculate the humidity based on the voltage output from the ADC Pi Plus def calcHumidity inval: Just one more question about calibration, I mean, how to set output current exactly from mA, can I replace ohm on emitter with trimmer to adjust output current? I could probably just use number 5 instead of Vsupply calculation, because voltage regulator should be pretty exact. Can you clarify your own ideas first and them come back with a more clear question?

Hi, It works great!!! Vout is voltage from sensor and Vsupply is Arduino’s supply voltage. Thread starter stuplja Start date Mar 3, Hi, Thanks a lot, I’ll try it immediately and let you know You can find a complete example of demo-hih You also mention temperature sensors and one well known voltage regulator.

My mind is too tired, I guess. I have one more HIH sensor, but it only outputs 3. Datasheets, Manuals or Parts. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at This can be done with a simple while loop.

I’ve done that, but, at the end, I used 56ohm and 50ohm multiturn hlh to get “real” value and also, I’m planning to go to meteo station to compare results with their RH sensors One more thing, can you, please, tell me in which software you done simulation and can you send me file to try myself?

I suppose it will help me to better understand whole circuit. Again thanks very much.

We apologize for the inconvenience…

Please tell us how we can improve this article: You will need to enable i2c on your Raspberry Pi, see our other tutorial on i2c: Not related to my issue. As True is always true the while loop will keep running until you exit the program with a Ctrl-C.

In order to clear the console for each read we need to issue a clear command.
