Finding a Data Logger 


I am struggling to find a data logger that works for my needs and am wondering if it is easier to build one, or if someone might have any suggestions for where to look.

The data logger needs internal clock and to be able to pass a supply voltage to connected hardware (3.3 V DC to 5.0). It needs at least one analog input but having 1 or 2 others is a bonus. And it needs at least two digital (serial) inputs with UART (3.0V levels, max. 3.3 V), 19200 baud, 8 data bit, 1 stop bit, no parity, no handshake.

I'd appreciate any suggestions! I am very new to this and am still learning what to look for.


I believe an Arduino MKR ZERO would meet all those requirements. May I ask what kind of project is it for? Some more context would help with suggestions. 

Hi Andrea, for the real time clock, you may want to add a GPS module to the setup and synchronize the internal clock with the received GPS time. Regarding the other requirements an Arduino or Raspberry will likely do the job.

I think it's important to state whether you have a lot of power available or not. If not, it would rule out the Pi. If you do, then you have a lot of flexibility but would have to add an external chip for the ADC.

So, would the use case have sufficient power to power a Raspberry Pi continously for the data logging period?
