Hi guys
I'm working on a research project in wich we want embeed sensors and logic, an ESP32, inside building's pillar surrended by concrete.
The esp32 collect data throught sensors, process them and send it to a sink using Bluetooth
Conditions:
- The device then can be never removed or replaced once is deployed (is in the concrete pillar)
- The device is externally powered by a electrical source (cables) then power is not a constraint.
- The data communication between sensors are made using Bluetooth. We have tested that we can transmit data from inside concrete to an exteranl sink that could be a phone.
- The device do not needs to store (write on memory) datas, the devices just reads process and sends enviromental datas. The deive can use READ ONLY MEMORY ROM to store the code no data store is needed.
Question(s)
- There are kinds of memories (flash on not flash), even ROM (read only memory) that are suitable to store code/data (informations) for LONG (100-200years) time without fail with a size of 4MB or more?
- If yes where i can find them, i mean where i can buy? Wich producer ecc..?
- How i can integrate these memories in the ESP32? Can i replace them to replace the flash? Is it possible to do that?
- How i can program such memories? I mean how can i "flash" these kind of memory?
