Particle boron alert prototype

Posted 2 days ago

Worldwide

Summary

I have a Particle Boron and want it turned into a small proof-of-concept that watches two reed switches and a single split-core current transformer. Whenever either switch changes state or the CT reports a reading outside user-defined limits, the Boron should push an SMS straight to my phone. Please build the firmware, wire the sensors, and set up the cellular messaging so the text includes three key pieces of information whenever a condition is met: the live state of each reed switch, the measured current, and a timestamp noting when the limit was crossed. I also need your guidance in deciding the actual thresholds for both the switches and the current transformer, so factor parameter-setting into the workflow. A concise wiring diagram, commented source code ready for Device OS, and a quick start note that shows me where to drop my mobile number will complete the job. Once everything is flashed and tested on your bench, walk me through a power-up test over video so I can see the alerts fire in real time:
