HDC1080: Using sensors in field trial

Part Number: HDC1080

Hi guys, Im an Arduino tinkerer and I just got some HDC1080 that I want to try out as coffee meters.  When I got them and saw they needed to be soldered by machine I was a bit disappointed.  I dont think I can solder those by hand, although Ill try :-)

I saw that there is an evaluation module that comes with a USB jack and I also found these sensors on tindie with a I2C interface pins.  I am wondering 2 things:

1. What kind of device must I plug in the usb jack of the EVM in order to read the data/view on display?  These things will need to be in a humid greenhouse environment where coffee is dried.

2. Im going to need about 20 of these for a full scale trial.  Is there another package where I could daisy chain or somehow communicate 20 of these?  Im wondering about a pre-made package.  I can connect them to a mcu like Arduino and have them send the info over bluetooth but it would be a waste of MCUs.

I also have no electricity for the trial so bluetooth might not be desirable.  I would be better to just have a module where I can display about 10 of these sensors on an LCD.  Im just wondering if there is a pre-designed package of this sensor which contains many of them in tandem?

Thanks

  • Hi Marcio,

    the HDC1080EVM is thought to be used in combination with the Sensing Solution EVM GUI, that works under Windows PC. You can download it from the following page:

    www.ti.com/.../hdc1080evm

    Please consider that the evm can be broken apart, and you can use the sensor module alone without to need to solder the part by hand.

    Unfortunately we have not devices that can put in daisy chain, so you should use a i2C multiplexer to connect many of them to a single MCU.

    Please let me know if this replies to your questions.

    Best regards,
    Carmine
