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.

Dear Sir, I have strong experience with embedded systems, industrial monitoring, Particle devices, and sensor interfacing. I can turn your Particle Boron into a reliable proof-of-concept that monitors the two reed switches and split-core current transformer, then sends SMS alerts immediately when alarm conditions occur. I can handle the complete workflow: • Firmware development for Device OS • Reed switch interfacing with debounce and event detection • Current transformer signal conditioning and calibration • Cellular SMS integration and alert formatting • Threshold setup guidance and tuning • Bench testing with live demonstrations Each SMS alert will include: • State of reed switch #1 • State of reed switch #2 • Measured current value • Timestamp of the event/alarm Deliverables: 1. Fully commented Device OS firmware ready to flash 2. Clear wiring diagram for the Boron, reed switches, and CT sensor 3. Threshold/calibration guidance for reliable triggering 4. Quick-start instructions showing exactly where to place your phone number and settings 5. Live power-up/video demonstration showing alerts firing in real time I also understand the practical side of CT sensors, including burden resistor sizing, ADC filtering, noise reduction, and safe isolation practices, so the readings will be stable and usable rather than just approximate lab values. Best regards, Hamza Electronics Engineer

Hi there, As an accomplished and versatile Embedded Systems Engineer and Prototyping expert, I'm well-suited to bring your Particle Boron project to life. Within my vast array of skills and experiences, I've successfully built countless prototypes that align with the unique challenges your project presents. You'll benefit from my expertise in firmware development, sensor integration, and cellular messaging systems - all skills your project requires to completion. Given the lack of specific start-end thresholds for both the switches and current transformer in your brief, my deep understanding of parameter-setting will be invaluable. I'll determine best-fit levels considering your needs, ensuring accurate notifications. Moreover, after delivering a concise wiring diagram, well-commented source code, and guidance on where you can input your mobile number – I'll conduct a detailed power-up test over video ensuring that everything operates perfectly in tandem.

Hello, I’d be glad to build this Particle Boron proof-of-concept for you. I have experience with embedded systems, sensor interfacing, and cellular-enabled IoT alert systems using Arduino/ESP32-class hardware and cloud integrations. For this project, I can: • Interface and monitor the two reed switches and split-core current transformer with the Particle Boron • Develop clean, well-commented Device OS firmware with configurable threshold parameters • Configure SMS alert functionality so messages include: * Reed switch states * Live current measurement * Timestamp of the triggered event • Help determine practical current thresholds and trigger logic based on your use case • Provide a concise wiring diagram and quick-start setup instructions, including where to insert your mobile number • Bench test the complete setup before delivery • Conduct a live video walkthrough to demonstrate alerts firing in real time and assist with first power-up I can deliver the initial working prototype quickly and keep the code modular so future expansion is easy. Looking forward to working with you. Best regards, Usama
