Project description:
"I’m building a fully-featured monitoring and control hub for my indoor vertical farm and need an experienced Raspberry Pi specialist to steer the process from concept through working prototype.

What I already have in mind
• Raspberry Pi as the central MCU
• A mix of I²C, UART and analog sensors for environmental data
• A simple web interface plus push notifications to my phone and any browser-based PC

What I need from you
1. Hardware architecture
– Pin-by-pin wiring diagram covering temperature-humidity probes, CO₂ sensors, ultrasonic or float-based tank-level sensors, flow switches (NO/NC), pH and EC probes, plus relay boards for fans, pumps and dosing heads.
– Parts list with distributor links so I can order everything in one go.

2. Software stack
– Python (or another Pi-friendly language you recommend) scripts or services to:
• read each sensor at defined intervals
• log data locally and to the cloud
• drive relays for fan speed, nutrient dosing and pumps based on configurable setpoints
• trigger SMS / push / email alarms on threshold breaches or sensor faults.
– A lightweight web dashboard that runs on the Pi, shows real-time charts and lets me tweak setpoints from any device on the LAN or remotely via HTTPS.

3. Deployment guide
– Step-by-step instructions for imaging the SD card, installing libraries, securing the OS and enabling remote updates.
– Testing checklist so I can confirm every sensor, relay and alarm path before the system goes live.

4. Support & refinement
– At least one review cycle after I build the first unit—if something fails the checklist, help me debug it.
– Advice on best-practice enclosure, cable management and EMI mitigation inside a humid grow environment.

Experience with Node-RED, MQTT, InfluxDB + Grafana, or similar frameworks is a bonus, but I’m open to your preferred toolchain as long as it stays Pi-friendly and well-documented.

Deliverables are the complete wiring plan, commented source code, the web UI, deployment notes, and post-build troubleshooting assistance. If you’ve completed similar horticulture or industrial automation projects, I’d love to see them." (client-provided description)
