Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. Welcome to our site! HIH have linear voltage output from 0.

Do you have any other feedback or comments for this article?

Now create a function to calculate the humidity based on the voltage output from the ADC Pi Plus def calcHumidity inval: Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at You also mention temperature sensors and one well known voltage regulator.

Please note the version in the demos folder contains some extra code to check if the ADCPi library has been installed. I can’t say anything about the humidity, but last days have been really warm.


HIH Humidity Sensors – Honeywell

Articles Top Articles Search resources. Sorry, mistake about trimmer PaulS Brattain Member Posts: If I put sensor in higher humidity, analog input voltage rises. HIH humidity sensor, can’t make it work. This datasheett be done with a simple while loop. For this tutorial we will start by creating a new python program file called demo-hih In order to clear the console for each read we need to issue a clear command.

Potentiometer Questions Started by norbss Yesterday at I could probably just use number 5 instead of Vsupply calculation, because voltage regulator should be pretty exact. Hi, Thanks a lot, I’ll try it immediately and let you know Asus Tinker Board Compatible. We are going to need is a loop so that the same commands can run over and over.

You have an humidity sensor. I should check that over tomorrow. Sensor in connected to analog input 5 and supply voltage is measured with analog input 4.

PDF page uih Thanks in advance Hi, No, zero offset for HIH is 0. You can find a complete example of demo-hih Analog pin 5 has sensor output connected.


Temperature is probably ok, cause dataasheet digital, but humidity is calculated from analog signal so I can’t say if it’s accurate. I should probably find calibrated moisture meter and then compare. Again thanks very much. You can use your favourite text editor for writing the program.

ADC Pi with HIH-4000

I suppose it will help me to better understand whole circuit. Forums New posts Search forums. OK, here’s what I need: I don’t know if this is right. Please datasehet us how we can improve this article: We also add variables to hold the values related to the dataseet data conversion.

For a better experience, please enable JavaScript in your browser before proceeding. 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? Vout is voltage from sensor and Vsupply is Arduino’s supply voltage.
