I can’t say anything about the humidity, but last days have been really warm. Temperature is probably ok, cause it’s digital, but humidity is calculated from analog signal so I can’t say if it’s accurate. Was this article helpful? Asus Tinker Board Compatible. The art of getting good answers lies in asking good questions.

The AB Electronics python library uses another library called python-smbus, you can install it using apt-get with the following commands. What is your sensor output range?

Not related to my issue. Long time passed since school and math lessons.

Thread starter stuplja Start date Mar 3, 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 have one more HIH sensor, but it only outputs 3. You have an humidity sensor. You also mention temperature sensors and one well known voltage regulator. PaulS Brattain Member Posts: Analog pin 5 has sensor output connected.

ADC Pi with HIH-4000

PaulS on Jul 08, Potentiometer Questions Started by norbss Yesterday at Please tell us how we can improve this article: HIH have linear voltage output from 0. I suppose it will dataeheet me to better understand whole circuit.

Do you have any other feedback or comments for this article? If I put sensor in higher humidity, 4000 input voltage rises. Raspberry Pi Zero Expansion. 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

Sensor in connected datashheet analog input 5 and supply voltage is measured with analog input 4. By continuing to use this site, you are consenting to our use of cookies. OK, here’s what I need: Datasheets, Manuals or Parts. We also add variables to hold the values related to the sensor data conversion. There must be some error in my calculations.

I should check that over tomorrow. You can use your favourite text editor for writing the program.


In order to clear the console for each read we need to issue a clear command. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Again thanks very much. You can hib a complete example of demo-hih Hi, No, zero offset for HIH is 0.

Sorry, mistake datasheeg trimmer Welcome to our site! Vout is voltage from sensor and Vsupply is Arduino’s supply voltage.

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: I don’t know if this is right. Hi, Thanks a lot, I’ll try it immediately and let you know I could probably just use number 5 instead of Vsupply calculation, because voltage regulator should be pretty exact.

You will need to enable i2c on your Raspberry Pi, see our other tutorial on i2c: You must log in or register to reply here.
