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

ADC Pi with HIH Series Humidity Sensor

I have one more HIH sensor, but it only outputs 3. Again thanks very much. You will need to enable i2c on your Raspberry Pi, see our other tutorial on i2c: Datasheets, Manuals or Parts. By continuing to use this site, you are consenting to our use of cookies.

Welcome to our site! My mind is too tired, I guess. PaulS Brattain Member Posts: I could probably just use number 5 instead of Vsupply calculation, because voltage regulator should be pretty exact. Articles Top Articles Search resources. Forums New posts Search forums. I should probably find calibrated moisture meter and then compare. For this tutorial we will start by creating a new python program file called demo-hih Sensor in connected to analog input 5 and supply voltage is measured with analog input 4.


HIH humidity sensor, can’t make it work. 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?

What is your sensor output range? You also mention temperature sensors and one well known voltage regulator. If I put sensor in higher humidity, analog input voltage rises.

As True is always true the while loop will keep running until you exit the program with a Ctrl-C. I can’t say anything about the humidity, but last days have been really warm.

You can use your favourite text editor for writing the program. Hi, No, zero offset for HIH is 0. There must be some error in my calculations. Just one more question about calibration, I mean, how to set output current exactly from mA, can I replace hhi on emitter with trimmer to adjust output current?

Not related to my issue. PDF page 6 Thanks in advance HIH have linear voltage output from 0. You can find a complete example of demo-hih This can be done with a simple while loop.


We also add variables to hold the values related to the sensor data conversion. Was this article helpful?

ADC Pi with HIH-4000

I suppose it will help me to better understand whole circuit. Raspberry Pi Zero Expansion. Click here to register now. For a better experience, please enable JavaScript in your browser before proceeding.

Temperature is probably ok, cause it’s digital, but humidity is calculated from analog signal datashet I can’t say if it’s accurate. Long time passed since school and math lessons. 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.

Academic Hardware Products (myDAQ, myRIO)

The art of getting good answers lies in asking good questions. Please tell us how we nih improve this article: We are going to need is a loop so that the same commands can run over and over. Vout is voltage from sensor and Vsupply is Arduino’s supply voltage. Media New media New comments Search media. Thread starter stuplja Start date Mar 3,
