I should probably find calibrated moisture meter and then compare. Analog pin 5 has sensor output connected.
Academic Hardware Products (myDAQ, myRIO)
Now create a function to calculate the humidity based on the voltage output from the ADC Pi Plus def calcHumidity inval: This can be done with a simple while loop. Asus Tinker Board Compatible.

Again thanks very much. You will need to enable i2c on your Raspberry Pi, see our other dafasheet on i2c: Hi, No, zero offset for HIH is 0. Media New media New comments Search media.
We also add variables to hold the values related to the sensor data conversion. Was this article helpful?
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? As True is always true the while loop will keep running until you exit the program with a Ctrl-C.
Potentiometer Questions Started by norbss Yesterday at The AB Electronics python library uses another library called python-smbus, you can install it using apt-get with the following commands. Please tell us how we can improve this article: Replacement Transformer Started by ncag Today at 7: My mind is too tired, I guess.
humidity sensor HIH-4000 4-20mA current output
The art of getting good answers lies in asking good questions. In order to clear the console for datashdet read we need to issue a clear command.
PaulS on Jul 08, There must be some error in my calculations. Not related to my issue. Vout is voltage from sensor and Vsupply is Arduino’s supply voltage. To participate you need to register.
Hi, Thanks a lot, I’ll try it immediately and let you know Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at I should check that over tomorrow. If I put sensor in higher humidity, analog input voltage rises. Articles Top Articles Search resources. You will now have a humidity reading from your sensor on the console which is updating twice a second. I suppose it will help me to better understand whole circuit.
