This blog is create to help those who plan to get or use Sensirion humidity and temperature sensor in their project.
Here the EK-H5 kit and SHT75 sensor is show for more understanding. It basically just summary from my chapter 5 in air design challenge.
The product can be order here:
SENSIRION - EK-H5SENSIRION - EK-H5
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 this given link (http://www.sensirion.com/en/products/humidity-temperature/evaluation-kits/ek-h5/ )
SHT2x sensor that come together with the evaluation kit and SHT75 sensor.
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 will 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.
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 veiwer from Sensirion.
