Sensor Integration Jobs

I'm seeking a skilled PCB designer to create a board for mass production that integrates an ESP32 C3 Supermini with an HLK-LD2410C for sensor integration, specifically a presence sensor. Key Requirements: - Design must facilitate sensor integration - Components: ESP32 C3 Supermini and HLK-LD2410C - Must be suitable for mass production Ideal Skills and Experience: - Proficiency in PCB design software - Experience with ESP32 and sensor integration - Background in designing PCBs for mass production

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.

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...

Çiftliğimdeki basınçlı yıkama sistemini tam otomatik hâle getirmek istiyorum. Donanımım STM32 tabanlı olacak; ön panelde bir TFT ekran ve sayısal tuş takımı bulunacak. Benden beklenen, hem bütün yıkama senaryolarını çalıştıracak sağlam bir gömülü yazılımın hem de gerekli şema ve dokümantasyonun eksiksiz teslimidir. Gereksinimler • STM32 mikrodenetleyici üzerinde C veya C++ ile yazılmış, CubeIDE-ye uyumlu kaynak kodu • TFT ekranda kolay anlaşılır menüler, geri bildirimler ve hata uyarıları • Tuş takımı ile program seçimi, başlat-durdur ve parametre ayarı • Pompa, vana ve sensör I/O’ları için non-blocking kontrol yapısı • EEPROM / Flash üzerinde parametr...
