A device for reading and saving bioelectric signals of plants.
I will write a more detailed description once I recieve it from manufacturing and make software for it, but this device reads analog signals, amplifies them and reads them with a 16-bit ADC.
It also has a RTC, port for connecting a photodiode, ports for connecting a dirt moisture sensor, and a potentiometer which allows to somewhat manually write an information/note (for example you can agree that if it's set to 100% it's a note meaning "I forgot to water the plant")
And lastly, it has a MicroSD card slot for writing all of that data to the memory card.
It's meant for plant bioelectric signals, but it can be used for any analog signals.
