I have a Particle Boron development board and would like to create a compact proof-of-concept monitoring system using two reed switches and a split-core current transformer (CT). The device should continuously monitor the sensors and automatically send an SMS notification to my phone whenever either reed switch changes state or the measured current exceeds or falls below configurable threshold values. The firmware should be developed for Particle Device OS and include cellular SMS functionality. Each alert message should report the current status of both reed switches, the real-time current measurement from the CT sensor, and the exact timestamp when the event occurred. I would also appreciate assistance in determining and configuring appropriate threshold values for both the reed switch logic and the current monitoring to ensure reliable operation. As part of the deliverables, I need a clear wiring diagram, well-commented source code ready for deployment, and a brief setup guide explaining where to enter my mobile phone number and adjust configuration parameters. After the firmware has been tested on your hardware, I would like a live video walkthrough demonstrating the initial power-up process and confirming that SMS alerts are triggered correctly under different test conditions.

Hi, This Particle Boron prototype is a strong fit for my embedded/IoT experience. I can build firmware on Particle Device OS that continuously monitors two reed switches and a split-core CT, then sends SMS alerts whenever a state change occurs or current crosses configurable thresholds. I’ll deliver clean, well-commented source code, a clear wiring diagram, and a concise setup guide showing exactly where to enter your phone number and adjust thresholds. I can also help tune the reed switch logic and current thresholds for stable, reliable alerts. Each SMS will include both reed switch states, live current reading, and an event timestamp. Before handoff, I’ll test the workflow on hardware and provide a live video walkthrough covering power-up and alert triggering under different conditions. I’d be glad to help turn this into a compact, dependable proof of concept. Best, Miguel

Hi — Abror-Yakubov here. "PARTICLE BORON-BASED ALERT SYSTEM PROTOTYPE" — you need a reliable embedded monitoring device that can detect sensor changes and send accurate SMS alerts. I can develop the Particle Device OS firmware for your Boron board, integrating reed switch monitoring, CT current measurement, configurable thresholds, and cellular SMS notifications. Each alert can include sensor states, measured current value, and event timestamp. I’ll also provide clean commented source code, wiring documentation, configuration instructions, and help validate the system through testing of different alert conditions. I would first review your exact reed switch wiring, CT sensor model/output type, and required current measurement range to ensure the firmware and thresholds are configured correctly. Which split-core CT sensor model are you using, and what current range should the system monitor? Looking forward to working with you.

Hi there, You want a Particle Boron-based prototype that monitors two reed switches and a split-core CT, sending SMS alerts with real-time sensor data and precise timestamps when any state changes or thresholds are crossed. I can deliver well-commented Particle Device OS firmware with cellular SMS support, a clear wiring diagram, and a concise setup guide showing where to set your phone number and adjust thresholds. For the thresholds, I'll help you define reliable values for both the reed switches and current transformer, and make these easily configurable in the code. After bench-testing the firmware on my own Boron board, I'll provide a live video walkthrough showing power-up, sensor triggers, and SMS alerts under varied conditions. One thing I'll pay close attention to is debouncing the reed switches and filtering current readings, which prevents false alerts and gives more stable notification behavior. I'm motivated to earn a strong review and will work closely with you to make sure every detail matches your requirements. I'm ready to start as soon as you confirm the CT model you'll use, so I can match the calibration. Best regards, Nataliya H.

You need a compact Boron prototype that reliably detects both reed-switch changes and abnormal current, then sends one useful SMS containing every sensor state, the measured current, and an exact timestamp. I will lead the complete delivery: map the inputs and CT conditioning, define debounce and threshold logic, coordinate Particle-specific firmware support where required, integrate and verify the SMS path, test the event cases, and deliver deployment-ready code. The package will include a clear wiring diagram, commented Particle Device OS source, configurable phone and threshold settings, a short setup guide, and a live walkthrough covering power-up, both reed-switch transitions, and high/low current alerts. Calibration will use measured idle and operating values instead of guessed thresholds, reducing false notifications. Before starting, can you confirm the exact CT model and whether Particle Cloud plus an SMS provider is acceptable?

Hi there I can build the particle boron‑based alert system prototype you need. I noted the budget range of 30 to 250 USD and the requirement for Arduino C firmware with sensor integration. My plan is to start with a minimal hardware test board, write modular firmware to read the boron sensor, implement threshold logic, and drive the chosen alert output. I will then validate on the target microcontroller and provide a short demo you can run. The project can be delivered successfully because I have recent experience delivering Arduino firmware and sensor‑driven games on tight budgets. The price fits your maximum and the schedule allows thorough testing. Will the alert be visual or audible Is the sensor analog or digital Do you need wireless communication

I can build this proof-of-concept on the Particle Boron with a clean and reliable event-driven firmware structure focused on stable sensor monitoring and accurate SMS alerts. The implementation would include: - Continuous monitoring of both reed switches with proper debounce handling to avoid false triggers. - Real-time current measurement from the split-core CT sensor with configurable upper/lower thresholds. - SMS notification logic containing reed switch states, measured current value, and timestamp for every relevant event. - Centralized configuration section so phone number, timing parameters, and threshold values can be adjusted easily without modifying core logic. - Well-commented Particle Device OS firmware ready for deployment. - Wiring diagram and concise setup documentation. For the CT sensor, I would calibrate the analog readings and help define stable threshold values based on expected operating current ranges. I would also validate alert behavior under multiple simulated conditions before delivery. The final handoff would include a live video walkthrough showing device startup, sensor state changes, CT threshold events, and successful SMS delivery testing. Estimated delivery is 4 days including firmware validation, documentation, and demo preparation.
