Wireless data logger

Other Parts Discussed in Thread: CC3200

Hi,

I want to make a wireless datalogger with the following specs: 1 channel, 8-bit resolution, at least 200 kSps ADC speed, continuous wireless transfer to a computer. Now, with 200 ksps, I'd need to transmit 1600 megabit per second, so I guess some WiFi solution is needed. Also, the analog signal I'm sampling is 0-5V, so it would be preferrable with 5V tolerance, but if not, I could always make a voltage translator down to 3.3V. So I really just need to sample the data and shuffle it to the WiFi module. I don't need a two-way link, just continuous streaming from the data logger is sufficient. If I lose some packets it's not detrimental. The required range is around 100 meters LOS outside. I don't have any experience with WiFi modules before, so I thought I'd ask to get steered in the right direction.

Any recommendations for seamless and easy-to-start solutions? Like development boards which include both microprocessors, ADCs, and an easy to use WiFi module. Preferrably something as easy to use as the Arduino development environments.

Thanks!

Sorry, should say ".. need to transmit 1600 kilobit per second..."

100m LOS is on the upper end for Wi-Fi, doable with good antennas...possibly a focused directional antenna would be best.

For an end to end solution, you can always check out my CC3200 and Azure solution...includes code and instructions....might give you some ideas - ssmlwf.azurewebsites.net

I am using the internal CC3200 LaunchPad thermometer, so you would nee to make some alterations to make work with your ADC requirements. Also I am sending data to the Cloud and not a PC.
