Mystical Journeys India

Project Description: We are developing a premium smart grow box with integrated sensors (temperature, humidity, CO₂, air quality, water level, pH, TDS), LED lighting, ventilation, and a touchscreen interface based on ESP32. The system requires precise control, monitoring, and future integration with Wi-Fi and OTA updates. Required Skills: Strong knowledge of embedded systems (Arduino / ESP32 / STM32) Experience with sensor integration (analog and digital: DHT, MQ-135, BH1750, TDS, pH, etc.) Proficiency in circuit design (low-voltage power distribution, transistor/mosfet switching, relays, protection) Familiarity with PCB layout is a plus (KiCad or similar) Ability to work with display modules (TFT/OLED, SPI-based) Experience writing reliable and optimized C++ firmware Understanding of basic HVAC and hydroponics control systems is a strong advantage Clear documentation and modular code structure Responsibilities: Design and implement the full electronics architecture of the grow system Select components and optimize wiring for safety and scalability Program sensor data collection and logic-based control (ventilation, lighting, pumps) Prepare a solid firmware base for future OTA/Wi-Fi functionality Collaborate on integration with a graphical user interface on ESP32 Preferred Background: Background in mechatronics, electronics engineering, or related field Previous experience with smart devices, agricultural automation, or indoor environmental control
