Sensor in connected to analog input 5 and supply voltage is measured with analog input 4. What is your sensor output range?
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?
This can be done with a simple while loop. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at You also mention temperature sensors and one well known voltage regulator. 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? Was this article helpful? PaulS Brattain Member Posts: You will now have a humidity reading from your sensor on the console which is updating twice a second.
Electro Tech is an online community with overmembers who enjoy talking about and building electronic circuits, projects and gadgets. As True is always true the while loop will keep running until you exit the program with a Ctrl-C. The art of getting good answers lies in asking good questions. Potentiometer Questions Started by norbss Yesterday at Not related to my issue. Now create a function to calculate the humidity based on the voltage output from the ADC Pi Plus def calcHumidity inval: For this tutorial we will start by creating a new python program file called demo-hih Click here to register now.
I could probably just use number 5 instead of Vsupply calculation, because voltage regulator should be pretty exact. Articles Top Articles Search resources.
I can’t say anything about the humidity, but last days have been really warm. You dstasheet use your favourite text editor for writing the program.
humidity sensor HIH-4000 4-20mA current output
Temperature is probably ok, cause it’s digital, but humidity is calculated from analog signal so I can’t say if it’s accurate. You can find a complete example of demo-hih I don’t know if this is right.
We are going to need is a loop so that the same commands can run over and over.
HIH Humidity Sensors – Honeywell
Forums New posts Search forums. Asus Tinker Board Daatasheet. I suppose it will help me to better understand whole circuit. The AB Electronics python library uses another library called python-smbus, you can install it using apt-get with the following commands. HIH have linear voltage output from 0.
Please note the version in the demos folder contains some extra code to check if the ADCPi 4000 has been installed. We also add variables to hold the values related to the sensor data conversion. There must be some error in my calculations.
