(Best view still 1900 x 1200)
In this chapter I will introduce some detail for the hardware (humidity and temperature sensor) and a little bit on software.
Hardware:
Hardware is one of the important part for a device so I will try my best to go detail for this section.
I have list down most of the hardware use for this project (please refer to previous blog for detail).
BBB and BB view:
BBB
Testing the BBB out of the box. It just working like charm
Using the cable HDMI D to HDMI A from element 14 (http://sg.element14.com/jsp/search/productdetail.jsp?sku=2127550&COM=drawer-part-list+CMPNULL)
Plug to TV, power it up and it working with no issue. It also working with the DC-DC converter supply from power bank with no issue.
Will going for WIFI connection or Ethernet connection and try for programing in future after finish with the hardware.
BB View 4.3"
It toke me few hour to found the correct link for the image file support the BB view and few more hour to download it
I think better share it here so other have another alternative getting the file.
Tips: Google drive share file here (https://drive.google.com/folderview?id=0B7Dl_WxBoZJSSG0tNnU3RVpxUUU&usp=sharing) This share link is not permanent maybe broken without notice.
TI-SDK image and source code toke about 2hour each to download in Singapore.
The share file from Google drive with hope it will be faster then the given link.

SENSIRION EK-H5 & SHT75:
To the summary for this testing Sensirion EK-H5 + SHT75
Sensirion EK-H5 and SHT75 humidity sensor and temperature sensor is a complete set for testing.
This system only work in window OS. The application call Sensirion AG/USB RS485 Sensor Viewer.
It can be download from Sensirion webpage or by the given link (http://www.sensirion.com/en/products/humidity-temperature/evaluation-kits/ek-h5/ )
STH75 sensor and SHT2 sensor that come together with the evaluation kit.
Tips: please handle the SHT75 sensor with care because the PCB is small
This picture show the complete set of the Sensirion EK H5 and Sensor. It easy to setup.
There is no polarity for the sensor connection but it do not damage if install wrongly. So don't worry.
Software will show error when the sensor install wrongly. Just flip the sensor and problem solve.
This is the inside look of the USB converter. They using Cypress MCU for this and look like EZ USB Cypress chipset to me.
Almost remove the label to see the chip model he..he.. Maybe will do it if have request
Software:
I will show some of the software related to the using hardware. This will not cover the detail of the software for this project.
There are few option for BBB, CC3200 and MSP430FR5969. It come with IAR, Energia and CCS
I like the IAR but this one come with size limitation .
Energia is arduino similar platform. For those who using arduino it will be easy to get use of it.
USB Sensor Viewer
This is the software for the Sensirion sensor. I have tested with SHT2 sensor and SHT75 sensor.
Data also can be log using this software and the format is in excel sheet .csv file.
Picture show the USB Sensor Viewer work with SHT2x sensor.
This picture show the USB Sensor Viewer hock up with SHT75 sensor.
Face some issue at the beginning due to wrong polarity sensor install but problem solve when flip the sensor and reload the program (Tips: reload is place at the bottom right)
Taking some data with SHT75 sensor. Sampling rate at 1Hz
Maybe will make a more detail in future for this.
This is the example of data logging taking form the sensor using USB sensor viewer from Sensirion.
MSP 430 Software Platform
IAR
This is the IAR software for the MSP430 platfrom. This software can only use in Window OS.
Energia
Energia is arduino similar platform. This support OS platfrom and look like the only choice for MAC user.
CCS
CCS (code composer studio) from TI. Come with a lot of example and it just run in Linux and window.
This software is design to support a lot of MSP430 family. It will be long story if want to do a step by step for this, I think.
Some information related with the CCS but I think it not support the MSP430 family. I need to go a bit detail to tell about this GUI Composer from TI.
Category:GUI Composer - Texas Instruments Wiki
That all for software introduction more detail about software will be posted in the future chapter depend on which software is using for this project.
Interesting Information:
While doing search for example and getting reference form online. I just come across this spark io, they look interesting and using cc3000 TI WIFI module.
Plan to get one of this to try it out. But now can just pre order only
The spark is available in cpc Farnell. Have anyone know what the different cpc farnell and just farnell or element14??
CORECA - SPARK - SPARK CORE, WIFI DEV BOARD, CHIP | CPC
For simple data capture service.
Internet of Things application development platform
Another data capture service for easy and simple use.
