Sensor Integration Jobs

I need a detailed sketch for an automatic plant watering system tailored for indoor plants. The system will draw from a water tank and incorporates a safety shut-off mechanism. Key Components: - Sensors - Arduino/Raspberry Pi - Water pumps - Safety shut-off Ideal Skills and Experience: - Experience with Arduino/Raspberry Pi - Knowledge of sensor integration - Familiarity with water pumping systems - Ability to create clear, functional system sketches

I have an Arduino-based setup that drives DC motors and I need clean, well-commented code that handles speed control, direction changes, and automated stopping. The sketch can be written from scratch or built on what I already have; either way, I want the final file to compile error-free in the current Arduino IDE and be easy for me to tweak later. Here’s the core logic I’m after: • Speed control – PWM or another reliable method that lets me adjust RPM smoothly from zero to full throttle. • Direction control – forward/reverse switching triggered by a digital input or a serial command. • Automated stopping – when a limit switch, sensor, or timed event is triggered the motor should brake or coast to a halt, then wait for the next command. I...

PCB Design & Engineering for HydroNest RO Plant Controller 1. Project Objective We are developing a professional controller PCB for commercial/light-commercial RO water treatment plants under HydroNest India. The objective is to take our existing functional requirements, selected components/modules and control logic, and have an experienced electronics engineer design, optimize and finalize the complete electronic controller. We are not looking only for PCB layout work. The engineer should be capable of taking the requirements at a system level and developing the complete electrical design, schematic, component selection/optimization and production-ready PCB. ⸻ 2. What We Will Provide We will provide: * RO plant operating requirements and sequence * List of pumps, solenoid valv...

I need a compact, indoor-only training device that keeps my dog or cat within designated areas. The goal is simple behavior correction for containment, not trick teaching or general exercise. When a pet approaches or crosses a virtual or physical boundary, the unit should deliver a very mild shock stimulation—strong enough to deter, yet well within accepted animal-safety standards. Here is what I’m looking for: • A complete concept and schematic for the device, including sensor choice, power requirements, safety circuitry, and enclosure design. • Firmware or control logic that triggers the mild stimulus reliably and only when intended. • A brief user-setup guide so anyone can define or adjust boundaries indoors. If you can add optional sound or light cues ...

I’m building a compact IoT board that can collect sensor data, push it wirelessly to the cloud, and drive simple actuators—all on one reliable PCB. At the heart of the design I need a low-power microcontroller paired with the necessary sensors; wireless connectivity (Wi-Fi, Bluetooth or whichever protocol you recommend) will complete the link to the outside world. Here’s what I expect you to deliver: • Schematic and PCB layout files (Altium, KiCad, or similar) • Optimised BoM with readily available parts • Gerbers, pick-and-place, and fabrication notes • Basic firmware pin-map to confirm that the microcontroller, sensors, and control lines are correctly routed Please send a concise but detailed project proposal that shows how you’ll hit...

The shocker-testing machine on my line already has a full SCADA package in place, yet it keeps dropping communication with its PLC, attached sensors, and actuators. The HMI screens load fine, but tags freeze, commands fail to reach the field devices, and alarms flood the log. I need the existing project inspected, its driver or protocol stack corrected, and the link restored to rock-solid reliability—no redevelopment from scratch, just a clean, well-documented fix. Scope of work • Audit the current SCADA project, driver settings, and network configuration. • Pinpoint the root cause of the PLC, sensor, and actuator comms failures. • Implement and test the corrective actions so data reads accurately and control writes execute every cycle. • Supply a brief tec...
