Project Title: Plant Monitoring and Irrigation System Overview: This system is based on the ESP32-S3 and is designed to manage irrigation for a multi-floor building. Key Features: Multi-Floor Operation: The system controls three separate floors. Each floor's irrigation can be managed independently. Irrigation and Pump Control: Each floor uses a solenoid valve to regulate water flow. The solenoid valves are operated via MOSFETs. A relay engages an AC water pump when a MOSFET triggers a solenoid valve. Hardware Interconnects: Screw Terminal connectors are added for connecting the solenoid valves and the motor pump. A DC Jack is included to supply power to the system. User Interface & Connectivity: Two JST connectors are provided for integrating an OLED display, a rotary encoder, and a pushbutton. Future enhancements may include the addition of soil moisture sensors. Remote Control: The system is designed for future integration with Blynk IoT. Blynk IoT will offer both manual control and timer-based irrigation modes for each floor.

Cow health-monitoring wearable PCB for a cow-mounted device. Rear strap electronics target 20-25 g and front sensing assembly target about 15 g. Uses an ESP32-based sensor controller, 200 mAh LiPo battery, battery charging circuitry, and interfaces for ammonia, methane, IR temperature, and saliva sensing. Design must tolerate moisture, mucus, debris, vibration, fur contact, and tongue/lick exposure while remaining compact and lightweight for wearable use.
