I suppose it will help me to better understand whole circuit. Sorry, mistake about trimmer The art of getting good answers lies in asking good questions.

We apologize for the inconvenience…

HIH have linear voltage output from 0. Was this article helpful? We also add variables to hold the values related to the sensor data conversion. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday dztasheet Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets.

HIH humidity sensor, can’t make it work. Now create a function to calculate the humidity based on the voltage output from the ADC Pi Plus def calcHumidity inval: You have an humidity sensor. We are going to need is a loop so that the uih commands can run over and over.

Do you have any other feedback or comments for this article? Raspberry Pi Zero Expansion.

Articles Top Articles Search resources. Long time passed since school and math lessons. 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 nih in which software you done simulation and can you send me file to try myself?

For a better experience, please enable JavaScript in your browser before proceeding. Hi, Thanks a lot, I’ll try it immediately and let you know Can you clarify your own ideas first and them come back with a more clear question? I should probably find calibrated moisture meter and then compare.

Welcome to our site! You also mention temperature sensors and one well known voltage regulator. Analog pin 5 has sensor output connected. I have one more HIH sensor, but it only outputs 3. You will now have a humidity reading from your sensor on the console hihh is updating twice a second. OK, here’s what I need: Forums New posts Search forums. 40000 page 6 Thanks in advance I should check that over tomorrow.

For this tutorial we will start by creating a new python program file called demo-hih Media New media New comments Search media. 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.

Replacement Transformer Started by ncag Today at 7: 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?

Hi, No, zero offset for HIH is 0. Asus Tinker Board Compatible. In order to clear the console for each read we need to issue a clear command.

I could probably just use number 5 instead of Vsupply calculation, because voltage regulator should be pretty exact. Datashet here to register now.

My mind is too tired, I guess.
