Plant Factory Environmental & pH Monitoring
Five-second logging of temperature, humidity, CO2, and pH for cultivation-data analysis.
PnP IoTs used one combined environmental sensor and one pH sensor to collect four important cultivation variables and store them automatically on the customer’s PC.


Customer Requirement
- Collect temperature, humidity, CO2, and pH data.
- Store measurements on a designated PC.
- Provide detailed source data for smart-farm big-data analysis.
System Configuration
