Im developing a solution for a portable, 4g capable remote Level Transmitter.
I will be using an industrial rated transmitter that uses 4-20~mA.
The system will have a 12v power supply.
Here is my shopping list so far
Arduino MKR NB 1500 SKU ABX00019
Arduino MKR Connector Carrier SKU ASX00007
Gravity: Analog Current to Voltage SKU SEN0262
DC-DC Adjustable Step Down SKU CE07271
Dipole Antenna SKU X000016
Grave Cables SKU SS110990031
I have spent most of my time playing with Arduino. I am tying to keep the cost to a minimum whilst still making it easy to swap out components if they happen to fail.
Is there any options that would provide the same functionality? Better? at a similar price?
