Hello Joey, sorry for the late reply, the download is usually made on a pc since it has to be burned onto the SD card that will have the os for the Raspberry Pi after you have downloaded the image and burned it on to the SD card you should insert the SD card in the raspberry pi and turn it on, the Ubuntu standard setup will begin and after setting up your account and password you should be on the home screen there isn't anything you specifically need for the IoT Bit to work as is already included in the latest kernel version. I recommend you run in the terminal "sudo apt-get update" and "sudo apt-get upgrade" after the setup is complete and you have changed the time and date to have internet access this will ensure you have the latest packages installed. If you have ...

Hi, Baoguo_Wei We would love to test our product and yours together. Would you like to send us a sample unit. Hope you do well in your Kickstarter.

Hi SruthiK2, Do you get an error from the python script? and have you tried logging on to your Plot.ly account on another computer?

Hi jbrannon80 could you please post the exact command you put in cron tab and also the path to the Sensly_plotly file

Hi jbrannon80, Do you get an error from the python script? and have you tried logging on to your Plot.ly account on another computer?

Most pins are still available. The only one's that are reserved are the UART pins, GPIO 5 and GPIO 6. The I2C line is also used but you can connect multiple devices to this.

Hi,Could you please send us a screenshot so we can debug the problem.

Here is the Plotly Graph setup instructions for Sensly The Raspberry Pi Hat.https://www.instructables.com/id/Setting-Up-the-Se...

The Kernel panic may have been caused by the apt-get update, upgrade and dist-upgrade commands, the reason we add this to the script is to make sure the raspberry pi is at the latest version. This is to ensure that the raspberry pi is a close to our in lab test conditions as we cannot guarantee that the install will work on earlier versions. We are sorry that you have had these issues. There is a potential to recover your information by plugging your SD card into a computer running a linux os.In response to your second comment, would it be possible to screen shot the path you save it to and the file explorer view of the file location by opening a separate terminal and using the command scrot -s then clicking on the window you want to screen shot. This will help us find the issue.In term...

This will help us find the issue.In terms of the update.py not working it seems like the program or the board is hanging could you please try restarting the entire system and try again. If this doesn’t work could you tell me which raspberry pi you are using?Finally in terms of the output my first question would be where you did calibrate the sensors? Also I think I should point out that majority of the gases detected with the exception of CO2 shouldn’t be picked up normally if they are it would mean your home is has dangerous gases. If you would like to test the response of the sensors, you can you lighter gas to ensure that the sensor are responsiveHope this help and sorry for the delayed response

Hi Frank, Sorry for the delayed reply. The reason for this is that the MQ7 requires a special heating cycle to detect Carbon Monoxide. This cycle is 60 seconds at 1.4V and 90 seconds at 5V. The Sensor is ready to be read during the 5V stage so to prevent it being read during the 1.4V stage we set the value it outputs during this stage to a number that would not give any ppm reading. This is why you get those very high rs/r0 values on the MQ7. Could you please let me know in what envrionment you calibrated the Sensors in?

What disk imager did you use to create the SD card? We recommend Win32 Disk Imager if this doesn't work could you please screen shot the problem

Hi VladmirS22As with most electrochemical cells they tend to drift overtime so will need recalibration approximately every 3- 6 months. That is thebest way to ensure long term accuracy. There is a pre-heating/burn-in phase required to remove theprotective coating the sensors have when we receive them from the manufacturesbut this is typically 48 hours and only has to be done once. After that wetypically recommend heating the sensor for 15 minutes to stabilize readingsbefore logging any data. Also temperature does affect the sensor readings hence whythe datasheet provides a curve to relate the change in temperature to the rs/r0value which is used to calculate PPM. The reason we have located the BME280 soclose to the sensors is to account for the increased temperature caused by theproximi...

The reason we have located the BME280 soclose to the sensors is to account for the increased temperature caused by theproximity of the three sensors and use this to correct the rs/r0 value. Thisway we can have more than one sensor on our board

We are not ignoring your message just need a little time to confirm all the answer. We will get back very soon.

We have just updated the link.
