All in one CO2 Air Quality Sensor

1、Using silicon MEMS micro-pressure chip, fully digital calibration, temperature drift performance and stability are improved. 2、Two chip isolation methods：     • elastic silicone protection, mainly used for differential pressure measurement of non-corrosive gases of silicon and silica gel;     • 316L stainless steel isolation diaphragm protection, filled with silicone oil internally, suitable for measurement of media that does not corrode stainless steel .

♦High precision /high sensitivityfast moisture meter formeasuring various materials ♦Large screen LCD，It can be used day or night ♦Four modes Random switching ♦Humidity alarm Easily grasp humidity changes ♦Removable Separate probe  

♦High precision:  High precision of the measurement data.♦ Real-time monitoring and recording: Record the temperature and humidity changes on the APP.♦Scene linkage: The sensor can be used as a temperature and humidity data source, which allow you do many automated processes based on it.♦Third-party voice support: The sensor supports Alexa, Google Home Assistant. You can check the current temperature and humidity by voice.

● Small and portable design with a large screen;●A wide temperature range from -58°F to 158°F (-50°C ~ 70°C);● Read humidity and temperature levels so that you can regulate your household for maximum comfort;● Table stand and a magnetic backing for optimal placement;● Measures current readings and compares to daily records so you know how to best prepare for the day;●You can simply reset the temperature and humidity.
