Sensor Integration Jobs

LOOP every ~2 seconds, for each burner sensor independently: 1. Read current temperature from sensor 2. Add reading to a rolling 15-20 second window of recent readings 3. Compute rate of change over that window 4. IF temperature has plateaued (stayed within ~±2°C band) AND plateau duration > 10-15 seconds AND temperature >= 90°C: -> Trigger "BOILING LIQUID" alert - Sound buzzer: 3 short beeps - Send Blynk push notification: "Burner X approaching boil" - Enter cooldown state for this burner (~2 min, suppress repeat alerts) 5. ELSE IF temperature keeps climbing past ~120°C without plateauing: -> Trigger "DRY PAN / FIRE RISK" alert - Sound buzzer: continuou...

I’m finalising the hardware for a new piece of wearable technology and now need the firmware that will bring it to life. The sole purpose of this first release is health monitoring, so everything you write should focus on gathering and processing the following signals with medical-grade accuracy and minimal power draw. 2. What Is Already Completed (Do NOT Redo) 2.1 Hardware Design Deliverables (Final) - COMPLETED The following have been completed and reviewed: ●Final schematic design (Altium) ●ESD / EMI protection design ●Power tree & power integrity design ●RF separation strategy (LTE / GNSS / BLE) ●GSM + GNSS + sensor integration plan ●Final 4-layer PCB layout (controlled impedance) ●PCB stack-up definition ●BOM with alternates & footprint expectations ●Power IC replacemen...

I already have a two-screen interface finished in Squareline for my ESP32-CYD based nervoscope. All component IDs and events are set; what I am missing is the Arduino IDE firmware that brings it to life. Main screen • Shows battery level (%) • Rotates a gauge needle toward whichever of the two RTD probes reports the higher temperature Settings screen • Slider-controlled probe/needle sensitivity • Dark / light theme toggle • Information panel toggle • Screen-brightness control • Temperature unit toggle with Celsius as the default • Sleep-timeout selection Your task 1. Import the finished Squareline project, wire it to LVGL (or the display library you prefer) and produce a clean, well-commented .ino sketch. 2. Read both RTD sensor...

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 ...

I'm looking for an experienced hardware/embedded engineer to build a first working prototype of a wearable sensor vest for athlete movement and heart rate monitoring. Scope: Sensor 1: GPS + 9-axis IMU (accelerometer, gyroscope, magnetometer) — for speed, distance, direction, and position tracking Sensor 2: Heart rate sensing — open to your recommendation on approach (optical/PPG vs. ECG) for a first prototype, given the vest will be used during physical activity/sport Data transmission: BLE to a nearby tablet/laptop Physical form: lightweight vest/garment insert, worn on the back, under 150g target, minimum 3-4 hour battery life, sweat-resistant What I need from you: Schematic + PCB design Firmware for both sensor sets A basic enclosure (3D printed is fine for this stag...

Our upcoming construction-tech platform needs a purpose-built LiDAR module that delivers millimeter-level distance measurements on both indoor and outdoor sites. The ultimate goal is seamless, low-latency distance read-outs that speak directly to our embedded controller and feed real-time data into construction workflows familiar to civil and architectural teams. Key requirements • Distance-only measurement, no full 3D mapping • Consistent accuracy within a few millimeters across typical construction ranges • Stable performance both under roof and in open sunlight • Clean, well-documented firmware that exposes measurements via UART or SPI (existing MCU is ARM-based C/C++) • Clear calibration and verification procedure that site managers can execute withou...

The goal is to turn an Arduino into reliable timing equipment for track-day cars. I already know the core requirement: precise lap timing triggered by track-side sensors, with each lap time shown live on an attached LCD screen so drivers can see their results as they pass the pit wall. What I need coded is: • Accurate capture of a start/finish trigger (IR beam, magnetic reed, or similar—happy to follow your recommendation) • Millisecond-level lap calculation that stores the current lap, previous lap, and best lap in memory • Real-time display of those three values on a 16×2 (or comparable) LCD; the screen should auto-update as each new lap registers • Simple push-button reset to clear the session without rebooting the board Deliverables: 1. Clean, well-com...

I need a knowledgeable crop-management professional to help me get the most out of my current drip irrigation set-up. The goal is to fine-tune scheduling, flow rates, and moisture monitoring so the plants receive exactly what they need without wasting water or nutrients. You’ll start by reviewing the field layout, crop type, existing emitters, and pump capacity that I’ll share through maps, photos, and sensor logs. From there, I’d like clear, step-by-step recommendations on: • Ideal irrigation intervals and run-times for each growth stage • Adjustments for seasonal weather swings and soil texture variations • Practical ways to detect and prevent clogging, pressure loss, or uneven distribution • Any affordable hardware or software upgrades&mdash...
