Plant Factory Environmental & pH Monitoring
Five-second logging of temperature, humidity, CO₂ and pH creates detailed cultivation records for smart-farm analysis.
Detailed environmental records for cultivation analysis
The customer needed source data for smart-farm big-data analysis. One combined environmental sensor and one pH sensor collect four important variables and store them automatically on a designated PC.
Customer Challenge
- Collect temperature, humidity, CO₂ and pH data together.
- Store measurements automatically on a designated PC.
- Provide high-resolution source data for cultivation analysis.
- Keep the installation compact and easy to maintain.
PnP IoTs Solution
PnP IoTs connected a SA0-TMHMCO2 environmental sensor and a SC0-pH sensor to one PD-AWS-S8 RTU. AutoSave records all four variables every five seconds for condition comparison, crop-quality analysis and future automation development.
From field measurement to usable records
Hardware and communication architecture

| PC Software | AutoSave | Stores data automatically on the customer’s PC. |
Field installation and equipment
High-resolution records for cultivation decisions
A five-second interval creates detailed records that can support environmental-control comparison, crop-quality analysis and later automation. The same compact architecture can be expanded with additional sensors as the cultivation process develops.
View air conditions and nutrient-solution pH together.
Five-second records reveal short-term environmental changes.
Keep source data in accessible files on a designated computer.
Compare environmental conditions with growth and quality results.
Add more sensing or control functions as the farm develops.
