Not related to my issue. Thread starter stuplja Start date Mar 3, Hi, It works great!!!

Again thanks very much. What is your sensor output range? You have an humidity sensor. Articles Top Articles Search resources. The AB Electronics python library uses another library called python-smbus, you can install it using apt-get with the following commands.

We also add variables to hold the values related to the sensor data conversion. This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

I could probably just use number 5 instead of Vsupply calculation, because voltage regulator should be pretty exact. Potentiometer Questions Started by norbss Yesterday at Temperature is probably ok, cause it’s digital, but humidity is calculated from analog signal so I can’t say if it’s accurate.

Do you have any other feedback or comments for this article? You also mention temperature sensors and one well known voltage regulator.

humidity sensor HIH-4000 4-20mA current output

My mind is too tired, I guess. HIH humidity sensor, can’t make it work. This can be done with a simple while loop. Now create a function to calculate the humidity based on the voltage output from the ADC Pi Plus def calcHumidity inval: Hi, No, zero offset for HIH is 0. Vout is voltage from sensor and Vsupply is Arduino’s supply voltage. There must be some error in my calculations. Sensor in connected to analog input 5 and supply voltage is measured with analog input 4.


PDF page 6 Thanks in advance 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 should probably find calibrated moisture meter and then compare.

HIH humidity sensor, can’t make it work

I should check that over tomorrow. I can’t say anything about the humidity, but last days have been really warm.
