That link consistently brings me to a malware site. It could be me or it could be the link. Just warning you.https://www.google.com/search?q=RH+sensor+module+arduino ← not that i know anything about it
Hello,Wait a minute... what are you programming? What sensor are you using? Is it even programmable?
I have dozens of questions. Let’s start with those three?
I searched for “hcz j38” and couldn’t find anything. So let me tell you a hint. When you have the right part number, type it into the search bar and add “ Arduino” after it. You’ll usually get sample code, typical circuits and maybe even a library you can download.Hello,
hcz j38 Is the name of it but have no idea how to use it so that I can record the humidity.
Hi, I looked at the datasheet but it doesn't mention how I can use it with a LCD. I'm not sure how I should use the impedance vs %RH graph to help me...Show a picture of the sensor so we can read the ID.
Humidity sensor Multicomp HCZ J3B, most probably.
I suggest you to start furiously to search the datasheet. Do not be lazy.
Post the datasheet.Hi, I looked at the datasheet but it doesn't mention how I can use it with a LCD. I'm not sure how I should use the impedance vs %RH graph to help me...
Of course it doesn't. Why in the world would it? It's just a sensor, not a complete sensing/processing/displaying system. If you want to display humidity on an LCD, you're going to have to figure out how to do that on your own. It will involve not only the sensor, but signal conditioning circuitry, a processor (e.g., an Arduino), and the LCD as well-- plus a lot of programming of the processor to convert raw measurements into displayable results.Hi, I looked at the datasheet but it doesn't mention how I can use it with a LCD.
If it doesn't, you're going to have to do a LOT of learning before you can use this sensor.I'm not sure how I should use the impedance vs %RH graph to help me...
if you call Google Search - Wikipedia such . . . i have noticed the trend lately , that at the end of results list there is a higher concentration of "irrelevant" or commercial links (applies to more general search terms) -- some of which may pose potential hazards if you don't close them and click where it happens . . . sorry to say but i assume the members here have a brain and know how to get around in wwwThat link consistently brings me to a malware site.
Post the datasheet.
I've only been studying electronics for about 8 months by reading books and watching YouTube videos and decided that I wanted to make my next project using a humidity sensor.Chill out fellas. This is a new member who is just getting his/her feet wet.
The datasheet for HCZ-J3 is available here.

Now you need a system that will measure impedance and temperature.
How much experience do you have to tackle this?
I've studied C,C++ and assembly code. How can I make an approximation line from the graph or use the lookup table provided in the datasheet?If a program is not given on the Arduino site, do you have experience writing microcontroller (MCU) code? What language? Do you know how to use a look-up table or do an approximation of that line? You will also need to measure temperature.
You might be able to find a probe that has been linearized. You will still need to measure temperature, unless it includes that too.
This is an example of an integrated temperature and humidity sensor: https://www.maximintegrated.com/en/products/ibutton-one-wire/data-loggers/DS1923.html
I did not look at the datasheet -- I have to fix dinner first.
