Carbon Dioxide Detector, Built in WiFi Air Quality Monitor Independent CO2 NDIR Sensor with Polymer Lithium Battery 350mAh for Bedroom - Rosvola, Rosvolarpoz0ekf7u

• Independent CO2 NDIR Sensor: The self developed NDIR sensor and laser particle sensor are used at the same time. The independent CO2 NDIR sensor has higher accuracy and stronger anti interference than the semiconductor sensor. Automatic Brightness Adjustment: Can automatically adjust the screen display brightness according to the surrounding brightness so that the screen is visible and not dazzling. High Performance Chip: Capture the weak current generated during the electrochemical process and calculate the CO2 measurement results accurately. Built in WIFI: Cloud link, tracking at any time, intelligent analysis and refresh display. Mobile APP can be used to query data at any time, to remind the family to purify the air. Energy Saving: When no one is in use, the detector can automatically extinguish the screen to reduce energy consumption, and under this condition, the sensor can still transmit data to the cloud through WIFI and check the real time value through the APP., Manufacturer: Rosvola
