This mini article is part of a larger project an I will link to it at the end. For this project, I was required to use the TI HDC1000 and instead of buying a module, I decided to get samples and a make a PCB of my own. This would be great except I had to create the footprints which are almost microscopic! Anyways I got it made from SeeedStudios and I bought one of those ultra cheap hot air stations with no indications about temperature or airflow and some paste and got started. The reflow happened painlessly and I was pretty happy with myself. Before I move on to mounting any other parts, I decided to see if the HDC1000 was alive or had kicked the bucked in my hotair experiment.
So I started with soldering the header as well as power test pins and I hooked up the BusPirate. Har har har! I think I can explain the rest via a video and so…
Check out the video after the break.
Get an assembled Bus Pirate for $30, including world-wide shipping. Also available from our friendly distributors.
OK, first-steps, but progress nonetheless. Congratulations to the Author of the article…
But what is the motivation for using this temp/humidity part over other similar parts with capacitive humidity sensors? (Other than the extremely small footprint and putting the sensor’s humidity sensor exposure orifice at the bottom of the package?)
These parts humidity-capable capacitive sensors typically require special handling and/or calibration of the humidity data output to make them actually useful as far as I remember.. What is different about this part when it comes to the humidity sensor?
Unlike the commonly-seen temp/humidity modules we source from China, this thing has a proper data sheet! At first glance, it also appear to have better specs compared to most cheapo modules from China. Presumably, the data sheet would also have all you need to know about handling etc. Not a bad trade-off I think, if you’re setting yourself up for making SMD boards.
