Sensor Integration Jobs

We are developing a self-service kiosk dedicated to safe, accurate and reliable cash handling. The scope of this project is strictly machine development, electronics, embedded firmware and mechanical engineering. We do not want to use Raspberry Pi, ESP32, Arduino, an embedded PC or similar development-board solutions as the main controller. The objective is to design and develop our own complete machine architecture, including a custom controller PCB, embedded firmware, cash-handling mechanisms, sensors, actuators, power electronics and mechanical enclosure. Core Workflow The machine will allow a customer to: Insert banknotes and coins. Detect and identify every deposited cash item. Maintain and display the running deposited amount. Compare the deposited amount with the required bill am...

Objective: The goal is to design and develop functional prototype AFE(Analog Front End)/pulser-receiver system that can directly interface with any raw underwater transducer (200KHz to 1MHz) and deliver full echo-profile data to a Raspberry Pi. Description: I am looking for an experienced analog electronics / ultrasonic / sonar engineer to design and develop (physical device) a custom electronics board (AFE) to interface with a raw underwater ultrasonic transducer. The board will interface directly with a raw piezoelectric ultrasonic transducer and provide the complete transmit and receive signal chain required for underwater sonar. The basic architecture is: Raw Ultrasonic Transducer ↔ TX/RX Front End ↔ ADC ↔ Raspberry Pi / Processor Required Electronics The AFE should i...

Necesito un modelo funcional en TinkerCAD que represente una estación automatizada de control de nivel de tanque. El sistema debe: • Utilizar un sensor de presión para leer el nivel. • Activar un relevador que encienda una bomba (motor) cuando el nivel baje del umbral configurado. • Mostrar el estado mediante un LED RGB: rojo cuando la bomba está activa, azul cuando está inactiva y verde cuando el nivel se encuentra dentro del rango deseado (modo espera). Entrego el umbral inicial, pero quiero que quede documentado dónde ajustarlo en el código Arduino. El proyecto final debe incluir: 1. Esquema de cableado completo y limpio dentro de TinkerCAD. 2. Código Arduino claramente comentado. 3. Enlace público al c...

I am building a small-scale oil-handling package and need a Siemens PLC program that keeps product moving efficiently while making sure tanks never run dry. The core of the job is to write, test, and document logic that optimises flow, pulls accurate readings from our flow sensors and low-level sensor, and then drives the valves, pumps, and any other actuators that respond to those readings. Everything must tie neatly into the HMI; I’d like operators to have both a touchscreen view and a secondary PC or hard-key option so they can work comfortably from the panel or the control room. The system’s sole purpose is process optimisation, so response time and deterministic behaviour are critical. I am already committed to Siemens hardware (S7-1200 series with a basic comfort panel) ...

I have an Allen-Bradley CompactLogix processor installed at my facility in Ridgefield, NJ 07657 and I need a ladder-logic program that fully automates our conveyor line system. The goal is straightforward: once the operator presses START the line should sequence itself, react to its sensors, and shut down safely on faults or an E-Stop, all while remaining easy to troubleshoot. Hardware and software already on hand: 1- allen bradley 5069 l330er • CompactLogix controller with standard 24 V DC I/O cards • A mix of photo-eyes, limit switches and VFD-driven motors • Studio 5000 Logix Designer for programming What I expect from you • A clean, well-commented .ACD project file written in ladder logic • Tag database and I/O map that match my wiring • Brief...

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 q...

I need a skilled PLC programmer to develop a control system for an oil project. The PLC will be a Siemens model and will handle flow control and low-level sensing. Key Requirements: - Flow control management - Low-level sensor integration - Interface with sensors, actuators, and HMI Ideal Skills and Experience: - Proficiency in Siemens PLC programming - Experience with flow control and sensor integration - Familiarity with HMI and actuator interfacing Please provide relevant experience in your bids.

I have a junior engineer building the early schematics for an asset-intelligence prototype and I need an experienced embedded-systems specialist to guide the hardware design, write the firmware, and get the first units reliably streaming data to the cloud. The boards must interface with temperature, pressure and motion and more sensors, carry out real-time analysis, perform basic filtering, then aggregate and compress the packets before they leave the device. Security on the wire is non-negotiable, so please be comfortable implementing encrypted transport and key management on resource-constrained MCUs. You will collaborate directly with us on: • Selecting the optimal MCU / wireless stack and finalising the schematic • Integrating the three sensor types and validating their ...

I have an ESP32-D dev board and three unused PAA5100JE optical-flow sensors. I only need to bring one online first, confirm it streams clean motion data, then replicate the solution for the other two. What I already have • A sketch that compiles but never sees the sensor • All parts on hand, breadboarded and powered • Standard Arduino IDE installed on my end for quick testing What I need from you within the next couple of hours 1. Corrected or freshly written code that initializes the PAA5100JE, verifies it over SPI, and outputs X/Y delta values on the serial monitor at 115 200 bps. 2. A clear wiring diagram (hand-drawn is fine if neat, Fritzing/KiCad even better) that shows every pin between the ESP32-D and the sensor, including power, ground, CS, MISO, MOS...

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.
