If this happens, you can reset the CO2 sensors in the Settings accessed via the app.<\/li>\n\n\n\n<li>Auto switch off while using battery and screen auto off during night: When these settings are on then the device is set to switch off automatically when not plugged in\/ at night to preserve battery life.

(Short answer)<\/h6><div id=\"ac-1097811\" class=\"c-accordion__content\">\n<p>Our air monitors use auto-calibration and are calibrated at the factory. This means that you shouldn\u2019t need to calibrate again as long as the device is exposed to around 400-500ppm for a few hours every month. This can be done by taking the device outside or placing it next to an open window. If the device isn't getting enough exposure to outdoor levels, the sensors may drift over time. If this happens, you can reset the CO2 sensors in the Settings accessed via the app. <\/p>\n\n\n\n<p>If you are indoors in an environment like a school where the classroom is empty for around 10-16 hours a day then CO2 levels may drop to near outdoor levels and you won't have to take the device outside regularly. If your indoor environment is dusty, you may need to calibrate more frequently.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-pb-accordion-item c-accordion__item js-accordion-item no-js\" data-initially-open=\"false\" data-click-to-close=\"true\" data-auto-close=\"true\" data-scroll=\"false\" data-scroll-offset=\"0\"><h6 id=\"at-1097812\" class=\"c-accordion__title js-accordion-controller\" role=\"button\">Do I need to calibrate the CO2 sensors manually? (Detailed answer)<\/h6><div id=\"ac-1097812\" class=\"c-accordion__content\">\n<p>CO2 sensors, like all sensors, can experience 'drift,' leading to minor deviations in readings over time. Traditionally, this was addressed through manual calibration. However, modern CO2 sensors come with an automatic calibration feature, activated when the CO2 concentration returns to the atmospheric background level (around 400 ppm)*. This makes the sensor virtually maintenance-free for most users.<\/p>\n\n\n\n<p>In cases where CO2 levels don't return to atmospheric levels for an extended period, manual calibration may be needed. For users who require highly precise readings, a monthly manual calibration can be performed outdoors while keeping auto-calibration active.<\/p>\n\n\n\n<p>* The auto-calibration feature requires the user's environment to be kept airy for a period of time every day. In an office, school or home environment there are usually long periods of time during the day when no one is around and the CO2 concentration drops to atmospheric background values, at which point the auto-calibration will function properly. It is recommended that CO2 concentration drops to atmospheric background values at least once a week to keep the auto-calibration functioning properly.<\/p>\n<\/div><\/div>\n\n\n\n<div class=\"wp-block-pb-accordion-item c-accordion__item js-accordion-item no-js\" data-initially-open=\"false\" data-click-to-close=\"true\" data-auto-close=\"true\" data-scroll=\"false\" data-scroll-offset=\"0\"><h6 id=\"at-1097813\" class=\"c-accordion__title js-accordion-controller\" role=\"button\">What should I do if my device has stopped charging, and how can I diagnose the issue?<\/h6><div id=\"ac-1097813\" class=\"c-accordion__content\">\n<p>If your device has stopped charging, here are a few things to check:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Charging Duration:<\/strong> How long have you been charging it?
