We apologize for the inconvenience…

PaulS Brattain Member Posts: This can be done datzsheet a simple while loop. Please note the version in the demos folder contains some extra code to check if the ADCPi library has been installed.

I should probably find calibrated moisture meter and then compare. Articles Top Articles Search resources. We are going to need is a loop so that the same commands can run over and over.

Raspberry Pi Zero Expansion.

I should check that over tomorrow. There must be some error in my calculations. For this tutorial we will start by creating a new python program file called demo-hih The AB Electronics python library uses another library called python-smbus, you can install it using apt-get with the following commands.


Sorry, mistake about trimmer As True is always true the while loop will keep running until you exit the program with a Ctrl-C. Click here to register now. You can find a complete example of demo-hih Replacing a 4 pin leaded inductor with a 2 dztasheet Started by gkmaia Yesterday at I don’t know if this is right.

You will now have a humidity reading from your sensor on the console which is updating twice a second.

ADC Pi with HIH Series Humidity Sensor

Long time passed since school and math lessons. Datasneet also mention temperature sensors and one well known voltage regulator. You must log in or register to reply here. Asus Tinker Board Compatible.

ADC Pi with HIH-4000

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 can’t say anything about the humidity, but last days have been really warm.


PDF page 6 Thanks in advance PaulS on Jul 08, Datasheets, Manuals or Parts. I suppose it will help me to better understand whole circuit.

I’ve done that, but, at the end, I used 56ohm and 50ohm multiturn trimmer 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?

Please tell us how we can improve this article: Potentiometer Questions Started by norbss Yesterday at Sensor in connected to analog input 5 and supply voltage is measured with analog input 4.
