PaulS on Jul 08, I suppose it will help me to better understand whole circuit.

Temperature is probably ok, cause it’s digital, but humidity is calculated from analog signal so I can’t say if it’s accurate. Please note the datawheet in the datsaheet folder contains some extra code to check if the ADCPi library has been installed. If I put sensor in higher humidity, analog input voltage rises. In order to clear the console for each read we need to issue a clear command. Datashwet art of getting good answers lies in asking good questions.

Forums New posts Search forums. HIH have linear voltage output from 0. Was this article helpful? Not related to my issue. We are going to need is a loop so that the same commands can run over and over. PaulS Brattain Member Posts: I have one more HIH sensor, but it only outputs 3.


Articles Top Articles Search resources. Datasheets, Manuals or Parts. For this tutorial we will start by creating a new python program file called demo-hih You also mention temperature sensors and one well known voltage regulator.

Asus Tinker Board Compatible. You will now have a humidity reading from your sensor on the console which is updating twice a second. Sorry, mistake about trimmer You have an humidity sensor. Sensor in connected to analog input 5 and supply voltage is measured with analog input 4. Hi, Thanks a lot, I’ll try it immediately and let you know There must be some error in my calculations.

HIH humidity sensor, can’t make it work.

You can use your favourite text editor for writing the program. As True is always true the while loop will keep running until you exit the program with a Ctrl-C.

Please tell us how we can improve datawheet article: I can’t say anything about the humidity, but last days have been really warm. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at This can be done with a simple while loop.


Hi, No, zero offset for HIH is 0. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

My mind is too tired, I guess. Hi, It works great!!!

We also add variables to hold the values related to the sensor data conversion. Welcome to our site! OK, here’s what I need: I should check that over tomorrow.


You will need to enable i2c on your Raspberry Pi, see our other tutorial on i2c: Can you clarify your own ideas first and them come back with a more clear question? For a better experience, please enable JavaScript in your browser before proceeding. Analog pin 5 has sensor output connected. 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?

You can find a complete example of demo-hih
