Connectivity
The PT01 connects to your existing 2.4GHz Wi-Fi network (802.11 b/g/n). Sensor data is accessible via the web interface. No additional gateway required for basic connectivity.
Installation Guidance
Location
Mount or place sensor in a representative location within the monitored area. Avoid direct sunlight, ventilation outlets, and heat sources. Maintain clearance from walls (minimum 30cm) for accurate readings.
Power
PT01: Insert batteries or connect USB cable to power adapter.
Network
Ensure Wi-Fi coverage at sensor location. Connect sensor to 2.4GHz Wi-Fi network (802.11 b/g/n). Configure network credentials via device setup process.
Warm-Up
Allow sensor to warm up for 7 seconds after power-on before readings stabilize. Full sensor stabilization may take up to 30 minutes in new environments.
Frequently Asked Questions
The PT01 uses NDIR (non-dispersive infrared) CO₂ sensing technology with a range of 400–5000 ppm. Accuracy is ±5%.
