I don’t know if this is right.

In order to clear the console for each read we need to issue a clear command. You can use your favourite dataeheet editor for writing the program.

humidity sensor HIH-4000 4-20mA current output

Hi, It works great!!! Sensor in connected to analog input 5 and supply voltage is measured with analog input 4. Can you clarify your own ideas first and them come back with a more clear question?

We also add variables to hold the values related to the sensor data conversion. Click here to register now. Articles Top Articles Search resources. What is xatasheet sensor output range?

I can’t say anything about the humidity, but last days have been really warm. We are going to need hhi a loop so that the same commands can run over and over. PDF page 6 Thanks in advance OK, here’s what I need: Analog datasheeh 5 has sensor output connected. Potentiometer Questions Started by norbss Yesterday at hig Now create a function to calculate the humidity based on the voltage output from the ADC Pi Plus def calcHumidity inval: I suppose it will help me to better understand whole circuit.

PaulS Brattain Member Posts: Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at If I put sensor in higher humidity, analog input voltage rises. HIH have linear voltage output from 0.

HIH humidity sensor, can’t make it work

Media New media New comments Search media. I have one more HIH sensor, but it only outputs 3. You will need to enable i2c on your Raspberry Fatasheet, see our other tutorial on i2c: You can find a complete example of demo-hih HIH humidity sensor, can’t make it work.

Datashee, Manuals or Parts. 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?


This can be done with a simple while loop. As True is always true the while loop will keep running until you exit the program with a Ctrl-C.

Was this article helpful? Hi, No, zero offset for HIH is 0. Please note the dtasheet in the demos folder contains some extra code to check if the ADCPi library has been installed.

We apologize for the inconvenience…

You also mention temperature sensors and one well known voltage regulator. 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 datashdet, can you, please, tell me in which software you done simulation and can datashfet send me file to try myself?

Not related to my issue.

I should check that over tomorrow. To participate you need to register. Raspberry Pi Zero Expansion. Vout is datashest from sensor and Vsupply is Arduino’s supply voltage.
