    We need to develop a project that monitors the voltage/current SCT013 and sends ...voltage/current SCT013 and sends alerts by SMS in fault or voltage change, and in turn triggers the peristaltic pump using ESP32 LoRa and powering by battery. PCB Design + Schematic Circuit + Code is Needed, If you have something else to be adding is welcome to proyect.

    There is an off the shelve temperature switched called the w1209 wh...noise. Further I need it to be hard set at 36C, no buttons, no display. Additionally, the w1209 runs on 12V. I need it to run on 7.2V. If possible it should have a charging circuit for lipo 2s pack as well. Power source should be a micro USB charger. No idea if all this is possible.

    I have a PCB Design which has been tested ok, it just needs re-designing to make it more space efficient. The tracks can be double sided but they need to be done so the PCB can be prototyped with a CNC PCB Mill. Components will be all discrete/through hole type. The PCB Takes a 12vdc Signal to a relay, the relay triggers a shunt coil of an MCCB.

    Require a pcb gerber file and programming for portable inbuilt memory cctv camera. Its main function is automatically compression of video i...50mb without loosing video quality. This compress depends upon size of video like after 1 GB or depend upon time like after 1 hours. This all things depend upon your hardware circuit designing and programming.
