GSM Remote Control – Temperature Control
Part 3 – Assembly

By on January 8, 2011
Pin It

For the GSM temperature controller we have provided a double-sided PCB with plated holes, made by photoengraving; once you have the board you can start  the assembly with SMD components.
The thermal probe can also be mounted out of the PCB, connecting it somewhere else by means of a three-conductor cable, at least 20 meters long.
