The ESP32 is low cost, low power, system on a chip. It can be
connected directly with a WIFI modem or through Bluetooth. It has
several pins that can be configured for both analog and digital inputs.
It is perfect for bringing sensor data in from the physical world and
uploading the data to the Internet. At Expert Coders we are experts at
programming the ESP32. We can also build your cloud server to display
your information over the Internet. If you prefer a desktop app to view
your data, we can do that too. Finally, at a cost as to the time of this blog post of 2 for $15, you cant beat the price.
The ESP32 is
great because it can be paired with a mobile hot spot or sim card router
to upload your data from remote locations. Mobile hot spots are
reliable, and readily available. They are also relatively cheap. You can
also stay up to date simply be switching out modems. This is a great
way to go because 2g and 3g wireless technologies are about to become
obsolete, and 5g as of this writing isn't here yet. Using WIFI for
uploading your data is the way to go.
