Your 24-hour no-data-loss test requirement is exactly the kind of acceptance criteria I build toward from day one, not after. I've shipped ESP32 environmental monitoring nodes that ran continuously in the field, so I know where the failure points hide — sensor drift, brownouts, and reconnect logic. Here's what I bring to this: → Built an ESP32 irrigation monitor with soil-moisture and environmental sensors publishing over MQTT, hitting 40% water savings in real deployment. → For your range and power balance, I'd lean LoRa or Wi-Fi with deep-sleep duty cycling — I'll recommend after checking your field distance. → Full stack in-house: sensor selection, schematic, PCB layout, firmware, and a working dashboard, so you're not juggling vendors. For this scope, the cost would be 1000 INR, covering hardware design, firmware, dashboard, and all documentation. Happy to walk you through my approach and past work on a chat.

Hi, I can develop this complete low-power environmental monitoring platform, covering **sensor selection, schematic, compact PCB layout, firmware, wireless communication, dashboard/parser and documentation**. I have completed **ESP32-based IoT sensor systems** involving temperature/humidity and air-quality monitoring, MQTT communication, custom PCB development and low-power field devices. I also have experience with **BLE, Wi-Fi, LoRa, cellular/GPS and RF integration**, so I can select the communication method based on your required range, power budget and deployment environment. For a first prototype, I would evaluate **LoRa for long-range, low-power field deployment** or Wi-Fi where infrastructure is available. The firmware can provide configurable sampling, structured packets, reliable transmission/retry handling and clear serial/dashboard visualization. I will provide the complete **source/build files, schematic, PCB files and renders, BOM with part numbers, flashing instructions, calibration/testing procedure and concise PDF user/deployment guide**. I can also structure the firmware cleanly so future sensors or communication protocols can be added easily. I have **16 years of embedded hardware and firmware R&D experience** with ESP32, STM32, custom PCBs, IoT, sensors and wireless systems.

Hi, I can develop this environmental monitoring system as a complete embedded solution, covering both hardware and firmware. I have hands-on experience with ESP32/STM32/Arduino, sensor interfacing, schematic design, PCB layout and embedded communication protocols. My approach would be to select suitable low-power temperature/humidity, air-quality and soil-moisture sensors, design the compact PCB, develop the sensor drivers and wireless communication firmware, and provide a simple serial/dashboard interface for monitoring the data. For field deployment, I can evaluate Wi-Fi, BLE or LoRa based on the required range and power budget, with LoRa being a strong option for long-range low-power monitoring. I will provide complete source files, schematic, PCB/Gerbers, BOM, firmware, flashing instructions and concise documentation. I can also structure the firmware for configurable sampling intervals and reliable packet transmission. I can work toward the specified 24-hour validation, wireless reliability testing and clean, warning-free documented code. I’m ready to discuss the required range, sensor accuracy, sampling rate and power target before starting.

Hello, I’m an Electrical & Electronics Engineer with practical experience in electrical design and PCB development. I can help you develop this environmental monitoring system from sensor integration and schematic design through PCB layout and embedded implementation. My approach would be to first select suitable low-power temperature/humidity, air-quality, and soil-moisture sensors, then design the schematic and compact 2-layer PCB in KiCad. For communication, I can evaluate Wi-Fi, BLE, or LoRa based on your required range, power consumption, and deployment environment. I can also work on sensor interfacing, data acquisition, packet formatting, wireless communication, and a simple serial/dashboard proof of concept. I will provide organized source files, BOM, Gerber, firmware, flashing instructions, and concise documentation. I would divide the project into clear milestones: sensor validation → schematic → PCB → firmware → wireless communication → testing → final documentation. This will make it easier to verify each stage before moving to the next. I’m available to discuss your deployment range, expected battery life, sampling interval, and preferred communication method before starting.

Hi, I’m interested in developing your Embedded Environmental Communication System. I have hands-on experience with ESP32-based environmental monitoring, sensor integration, IoT communication, and embedded firmware. I have previously worked with BME688 for temperature, humidity, pressure and gas/air-quality monitoring, along with ESP32-based IoT systems and real-time data monitoring. I can use this experience to develop the sensor node and integrate soil-moisture sensing as well. For the wireless communication, I can evaluate Wi-Fi, BLE, or LoRa based on the required range, power consumption, and deployment environment, and implement a reliable data transmission structure with configurable sampling intervals. The work can include: Sensor selection and hardware design Schematic and PCB layout ESP32/MCU firmware and sensor drivers Wireless communication and data packets Simple dashboard/serial monitoring Sensor calibration and testing 24-hour reliability testing BOM, Gerbers, source code and documentation I’ll focus on keeping the design compact, reliable, and suitable for low-power field deployment, while making the firmware clean and easy to maintain. I can start with the hardware and communication architecture and then proceed toward the tested prototype. Thank you.

Hello, I can help develop your environmental monitoring prototype through Leovanne. Our in-house APEX work includes ESP32 firmware, sensor integration, USB/Bluetooth links, an Android technician tablet and a monitoring dashboard, with documented build and hardware checks. Relevant example: https://www.freelancer.com/portfolio-items/11587363-apex-esp32-and-android-tablet I propose phased delivery: 1. Agree sensor accuracy, sample rate, range, power budget and endpoint. 2. Build sensor firmware and wireless communication with timestamps, reconnect handling and buffering/retries. 3. Prepare schematic, BOM, PCB layout and a simple dashboard/parser around the validated prototype. 4. Run the agreed 24-hour test and deliver source/build files, flashing instructions and a PDF guide. Wi-Fi or LoRa selection depends on range and power. Air-quality calibration and acceptable data-loss/recovery criteria must be defined for the chosen sensors and link. Please confirm deployment range, power source, sensor preferences and access to local assembly/testing. Components, fabrication, shipping and external calibration/testing are separate costs. Production readiness follows prototype and PCB validation. INR 1,250/hour, capped at 20 hours/week. I will agree a phased hours estimate and timeline before development.

Hi, This matches my recent work closely. I built an ESP32-based industrial IIoT monitoring system that included: - Sensor integration (multiple sensor types feeding into a single controller) - Firmware for sensor sampling, data formatting, and wireless transmission - A Python-based dashboard for real-time visualization of incoming readings For your project, I'd approach it as: 1. Sensor selection/confirmation for temp/humidity, air-quality, and soil-moisture, with driver code for each 2. Wireless link: I'd recommend LoRa if range and low power are priorities (long battery life for field deployment), or Wi-Fi/BLE if the endpoint is nearby - happy to discuss trade-offs based on your deployment distance 3. Low-power schematic + PCB layout sized for field use 4. A simple serial parser or lightweight dashboard to visualize incoming data, plus a defined packet structure 5. Full documentation: BOM, build files, flashing instructions, user guide I'll validate with a extended test run to confirm stable readings and no data loss before handoff. Happy to share my IIoT monitoring project as a reference. Looking forward to discussing your deployment range and power constraints to finalize the wireless approach. Best, Deniz
