Hi, My bid is already including prototyping Cost. We can use FRAM for datalogger, and use electronic switch controlled by Microcontroller,so it can save power consume by chips. For MCU will use Low powered MCU such as STM32L working at low power and will be sleep all day long depending on configuration. PC Software can be Visual Studio based,or python based. I have 8 years experience as hardware and Firmware Developer. I have built many projects for various application, from hobbyst to military grade application. Let's discuss the details over chat. Best Regards, Rijal
