Smart 7'' CO2 Air Quality Monitor - WIFI Control Carbon Dioxide Sensor Tester, TUYA App

- CO2 (carbon dioxide) level in the room
- TVOC (Volatile Organic Compounds) concentration
- Particulate matter - dust (PM1.0; PM2.5)
- Air temperature and humidity
  The PT02 device indicates the level of air quality in the room, thus providing full control over the air. With the help of high-precision infrared sensors for CO2 and laser sensors for PM (microparticles) and TVOC (Volatile Organic Compounds) you can transform your room into a clean air zone.
 PT02 is capable of interconnecting with your purifier, humidifier or even your existing ventilation system. This is done through its WiFi connection protocol or via the RS485 port. Also, its power supply is programmable using the smart charger included in the package.
And with the WiFi function, you can check all quality indicators remotely through the Tuya Smart application, available in the App Store and Google Play Store.

       NOTE
1. To ensure the accuracy of detection, let the device stand outside for 10 minutes. It should be placed in a ventilated environment for 24 hours to automatically calibrate if the device needs to work in a confined space. You can also choose manual calibration.
2. Do not place the detector in heavily polluted environments (TVOC concentration > 20 mg/m3 or particle concentration > 500μg/m3) for a long period of time to avoid sensor damage.
3. Do not place the monitor in an extreme environment, such as an environment with a very high temperature or a very low temperature.
4. Dropping, hitting or disassembling the product may cause the detection to be inaccurate. Please store the unit properly.
5. To connect the RS485/Port output signal, please find professionals to do the wiring connection with the guide in the instruction manual (please check it in the packing box). Please pay attention to the danger of electricity during wiring connection.
6. For the IoT solution between the PT02 and other smart devices, such as fans, humidifiers, and CO2 generators, etc., please refer to the instruction manual in the box. Try to avoid wearing strong perfumes while using the PT02. This may affect the detection results.
