Particle Boron Alert Prototype -- 2

@amelectronics

Hi, I can handle this Particle Boron project end-to-end. I’ll integrate the two reed switches and split-core CT, develop the Device OS firmware, configure cellular SMS alerts, and include the switch states, measured current, and timestamp in each alert. I’ll also define the CT calibration and user-adjustable thresholds, provide a clear wiring diagram and commented source code, and document the flashing/setup process. I can test the logic on the bench and guide you through the final power-up test. I have experience with ESP32, STM32, nRF and other embedded platforms, including sensor integration, ADC/current measurement, wireless communication and firmware development. Please share the Boron model, CT part/rating, and expected current range so I can finalize the approach and estimate the exact timeline.

Hi there, I have carefully reviewed your Particle Boron monitoring requirements and can handle the complete proof-of-concept, including reed-switch inputs, split-core CT sensing, threshold logic, cellular SMS alerts, firmware, wiring, and bench validation. With nearly five years of experience in mechatronics, embedded systems, sensors, current measurement, cellular IoT, and C/C++ firmware, I can deliver clean Device OS code that reports both switch states, measured current, and timestamp whenever a configured condition is triggered. I can also help define practical current thresholds, provide a concise wiring diagram and quick-start guide, and support the final power-up test over video. Please send me a message so we can confirm the CT model, Boron version, and SMS service setup. Best regards, Samuel tshibangu

Hi, I can build the Boron prototype end-to-end: firmware, sensor wiring, threshold logic, and SMS alert workflow. My approach would be: 1. Confirm the exact reed switch behavior and the current transformer model/range 2. Define the alert thresholds and debounce/filtering rules 3. Implement the Device OS firmware for state monitoring and event detection 4. Send SMS with switch states, measured current, and timestamp 5. Provide a concise wiring diagram and a commented source package 6. Verify the system on bench and review the power-up test procedure with you To make the thresholds reliable, I would first need: - Reed switch type and normal/open state expectation - CT part number, burden arrangement, and expected current range - Whether SMS should be sent through a cloud service/API or another gateway - Your target mobile number format for the message setup I can keep the deliverable compact and practical so you have a working proof of concept quickly.

As an experienced mobile developer, I possess the skills and technical acumen to transform your Particle Boron device into a highly efficient alert prototype. I have more than 9 years of hands-on expertise in web and mobile development, particularly proficient in Android and iOS platforms. With special focus on incorporating SMS push notifications, I have a firm understanding of the required parameters for such systems as well as using cellular messaging technologies. My competency extends beyond just software - I am comfortable with hardware wiring as well. This is essential to wire the two reed switches and single split-core current transformer in your Particle Boron, according to your desired thresholds. My proficiency in utilizing different programming languages such as Java and PHP will enable me to optimize the firmware of your device for effective data acquisition and SMS generation. Moreover, my cost-effective approach combined with my commitment to providing timely support even after project completion sets me apart from other candidates. I would provide a concise wiring diagram, commented source codes ready for Device OS, and would diligently help you initialize the system on your phone. To assure you of the project's successful completion, I will also perform a thorough testing using your provided mobile number and walk you through its every feature over a live video demonstration. Allow me the opportunity to turn your ideas into a reality with this project. T

Hi, I can help build this Particle Boron proof-of-concept, including the sensor wiring, Device OS firmware, cellular SMS functionality, threshold configuration, and testing workflow. I can also structure the firmware so the key parameters are easy to modify rather than hard-coded throughout the program. For the CT, I’ll help determine appropriate upper/lower limits based on the expected normal operating current and sensor specifications. For the reed switches, we can define the expected normal states and debounce behavior to prevent false alerts from contact bounce. I’ll pay particular attention to reliable reed-switch debouncing, CT calibration/scaling, threshold handling, timestamps, and cellular connectivity so the POC behaves predictably rather than generating nuisance alerts. Please provide the exact Particle Boron model, Device OS version, reed-switch specifications, CT model/ratio, and expected current range. Once I have those details, I can confirm the wiring and implementation approach and get started. Best regards, Bharti

Hello, I'm bharghav, an Electrical Engineer with 10 years of experience, particularly adept at integrating sensors and developing robust embedded systems. I've carefully reviewed your Particle Boron project. I understand you need a proof-of-concept for monitoring reed switches and a current transformer, pushing SMS alerts with live states, current, and timestamps. I will develop the firmware, wire the sensors, and configure cellular messaging. We'll also collaborate on defining the alert thresholds. The project will deliver commented source code, a wiring diagram, and a quick start guide. After bench testing, we'll have a video call for a live power-up demonstration.

Hi there, I can build this Particle Boron proof-of-concept end to end: firmware for the two reed switches and split-core CT, SMS alerting, clean commented Device OS code, and a concise wiring diagram. I’ll structure the firmware so each alert includes the live reed states, measured current, and the exact timestamp when a threshold is crossed. I’ll also fold parameter-setting into the workflow so we can define practical switch and current limits before deployment. You’ll receive: - Device OS firmware ready to flash - Wiring notes for the Boron, reed switches, and CT - Cellular SMS setup guidance with a clear place to enter your mobile number - Quick-start instructions for bench testing After flashing and bench validation, I can walk you through a live power-up test so you can verify alerts in real time over video. Best, Panagiotis

Hi, New on Freelancer — 20 years of development experience behind us. We're taking our first few projects here at a fraction of our normal rate purely to build our review history. You get senior agency work at junior pricing; we get a review. Straight trade. To effectively monitor your Particle Boron setup, ensuring precise timing between the reed switches and the current transformer is crucial. I would start by configuring the microcontroller to handle state changes efficiently, minimizing latency. Could you share any existing firmware or code you have, so I can assess and optimize it?

Hello, I can build the Particle Boron proof-of-concept with reliable sensor monitoring and cellular SMS alerts. I can handle: • Two reed-switch inputs with proper pull-up/pull-down configuration and debouncing • Split-core CT integration with suitable signal conditioning and calibration • Configurable current thresholds and alert parameters • Alerts when either reed switch changes state or current crosses a limit • SMS containing both reed states, measured current and event timestamp • Commented Particle Device OS firmware • Clear wiring diagram and quick-start documentation • Destination phone-number configuration • Bench testing and a live power-up demonstration For the CT, I’ll first confirm its exact model and output type so the interface and calibration are correct. I’ll establish sensible initial thresholds from your expected normal operating range while keeping them configurable. The firmware will be modular, with separate sensor, measurement, threshold, alert and cellular logic. I’ll also use debouncing, filtering and hysteresis where appropriate to reduce false readings and repeated SMS alerts. I’m ready to start once you provide the Boron/CT details, expected current range and sensor wiring information. Best regards, Juan

This seems like a straightforward and well thoughtout project. I would ensure we are aligned on the requirements with initial correspondence. Share a system diagram with you. Order components. And build the firmware and test. Happy to design a basic enclosure as well.
