Sensor Integration Jobs

I’m developing a compact consumer-electronics product and now need a production-ready, double-layer PCB. I already have a partial component short-list (core MCU, power-management IC and a couple of sensors) but I’m open to your suggestions for supporting passives, protection devices and connectors that will keep cost and board real-estate under control. You will start from my block diagram and mechanical envelope, turn it into a complete schematic, then lay out a two-layer board that respects standard DFM rules for the major fabs (JLCPCB, PCBWay, etc.). Please route for low-noise operation—this gadget sits beside RF-speakers, so clean ground planes, controlled trace widths and sensible decoupling are important. Deliverables • Editable schematic and PCB layout fi...

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...

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.
