Budget: $10 – $30 USD

I need an Arduino base system to read a CAN BUS data and base on the it should either close or open a relay.
I have a device that communicate through CAN bus protocol. The protocol sends readings ( voltage, current, power etc), device state, error message etc. But all I want to read using Arduino is the SOC ( state of charge) value of the battery and use that to either open or close a relay.
