1st Problem :By Installations product IOT security systems build from Arduino it's really difficult to turn on laptop on side. Why? This is the reasons, the installations is to far sometime it need setup in high locations for make it more security from the bad person or cheater to destroy it.
(Sorry for no clear image) ( -_-)"
Follow by Image it's show no safe place to put our laptop and connect USB and get the Serial data from that Arduino up there . Another ways we need the long cable around 10 meter of USB cable to connect it our laptop in safe place. For solve this problem we need wireless for get the log and easy to configurations. ESP32 have bluetooth that we can use long range more than 30 meter.
(Summarize -> wire for data log is messy !)
After setup the systems. when we want access it by Internet and config it . The system not send us the right data we want . We don't know what the real problem there ? Have natural noise signal ? Storm when it's rain(Cambodia is country tropical it's usually rain and a lots storm ) ? Or our system has been stuck ??? And than we go there we got nothing we don't know the real problem it's make us wasted our time ,wasted our transportations to go there and wasting power of our brain to imagine the real problem .
So, for solve this problem we need to storage all data on SD CARD have time to Storage data .
(Summarize -> we can't stay with our hardware develop 24/7 we need storage to check all in one time).
Controller -> ESP32S WROOM
8 analog to digital Converter
Memory up to 32GB
Have External Serial
Have USB direct connect to device to log
It's help us to see and store our problem data direct with controller (arduino or another microcontroller etc. ) and our code problem via Serial(UART).
