With three different color CO2 concentration indicator(can be set on the app): the green means <800ppm, the yellow means 800~1500ppm and red means >1500ppm.
It can not only detect the CO2 for you, but also can shows the times and weather for you. (the time and weather display need to connect with the internet to achieve)
Using solid electrolyte chemical sensors, when the sensors in carbon dioxide gas, the two ends of the battery voltage difference, calculate the concentration of CO2 gas, with less interference, the detection is more stable.
APP remote check: After connect with the Perthings APP, no matter how far away you are from home, you can check the data on your mobilephones.
It can suitable for office, home, bedroom, living room, classroom and so on places.

1. This product consumes a lot of power. Although it can be used with 2 * AAA battery (battery not include), it is still recommended that you connect to the USB cable and plug it in to the power to use. It is estimated that two AAA batteries can only last about 15~30 minutes.
2.We suggest that the CO2 monitor be plugged in the power supplys for a long time. If it has not been used for a long time, the sensors needs to be calibrated automatically. Please plug in the power supplys and work for 24 hours, and then view test results.
3. Regardless of whether the CO2 monitor is turned on or not. long-term exposure to extreme environments such as high temperature, high humidity, and high pollution will seriously affect the performance of the CO2 monitor. This is the ca-se with most CO2 monitors on the market, please stay away from these environments.
