We need a PCB design with 3 main componenets:
- WIFI module/controller (ESP8266 or any recommendation): this will control whole system and send requests if wifi is available. It will also control power usage to improve battery life.
- SIM7000A: will be sending post requests every 15 minutes about sensor details.
- Must have 3 input pins (analogue, vcc, gnd): This will be reading an external hall sensor with cable.
- Battery: 3 volts battery.
- Button 1: Although the device will send automatically every x time, it should be posible to make it happen with a button.
- Button 2: Will enable WPS connection to wifi.
Things to take into account:
- The final product must be water proof so please consider in PCB Design.
- The device should be easily flashable with an arduino IDE to make adjustments or updates.

Hello, I am quite experienced at PCB design. Additionally I have worked with ESP8266 and SIM800 before and therefore could also help out with the development of your project outside of the PCB design
