Product Overview
MODBUS NGS02It is a negative oxygen ion concentration detection sensor used to measure the number density of negative ions in the air (pieces/cm ³). Negative oxygen ions are called "air vitamins", and the higher the concentration, the better the air quality. Sensors transmit data to Home Assistant through RS485 Modbus RTU, which can be used for environmental monitoring, health assessment, air display in scenic areas, and other scenarios.
Significance of Negative Oxygen Ion Concentration
| Concentration range (pcs/cm ³) | Air quality assessment | health impact |
|---|---|---|
| <100 | Poor (urban indoor) | Easy to induce headaches and fatigue |
| 100-500 | General (urban outdoor) | Basic maintenance of health |
| 500-1000 | Good (park green space) | Enhance immunity |
| 1000-5000 | Excellent (forest/seaside) | Has healing effect |
| >5000 | Excellent (waterfall/forest after rain) | Treatment level, regulates physiological function |
