Equipped with a high-precision sensor (10-year life), the detectable CO concentration range is 0~1000PPM (\u00b110%), the CO2 concentration range is 400~5000PPM [\u00b1 (50PPM + 5%)], and the temperature range is 14~122\u2109 (\u00b12.7\u2109) \/ -10~50\u2103 (\u00b11.5\u2103), humidity range is 0~95%RH (\u00b15%RH). The data is accurate without delay and monitored in real time.<\/li><li>\u3010CO LIGHT INDICATION & CUSTOMIZED ALARM VALUE\u3011The carbon monoxide monitor can present 3-stage light indication based on CO concentration. 0~99PPM (green flashing=safe), 100~149PPM (yellow flashing=warning), 150~1000PPM (red flashing=danger). By default, the CO monitor will sound an alarm when it reaches 150PPM. You can double-click the \"function button\" to customize the CO concentration alarm threshold. Note: The device must be in the \"CO\" interface before entering CO custom settings.<\/li><li>\u3010CO2 LIGHT INDICATION & CUSTOMIZED ALARM VALUE\u3011The carbon dioxide monitor can present a 3-stage light indication according to the CO2 concentration. 400~699PPM (green flashing=safe), 700~1499PPM (yellow flashing=warning), 1500~5000PPM (red flashing=danger). By default, the audio alarm sounds when it reaches 1500PPM. You can double-click the \"Function Button\" to customize the CO2 concentration alarm threshold. Note: The device must be in the \"CO\u2082\" interface before entering the CO2 custom setting.<\/li><li>\u3010LARGE CAPACITY BATTERY & FAST CHARGING\u3011The MINI 4-in-1 CO detector has a built-in 1000mAh lithium battery for long-lasting power. Support QC2.0, PD3.0, AFC, USB C UFP (BC1.2 DCP CDP SDP) and other common fast charging protocols 10~65W charging. When the CO detector is not operated for 5 minutes, it will automatically turn on the energy saving mode (the brightness of the screen will be reduced), and you can click the \"function button\" to turn on the backlight.<\/li><li>\u3010OUTDOOR LANYARD & MAGNETIC SUCTION\u3011The bottom of the CO CO2 air quality monitor can be placed freely, you can put it on the table in the living room, kitchen, bedroom, etc. And it is equipped with a special outdoor lanyard, which is convenient for you to carry and use in outdoor activities such as travel, camping, picnic, and adventure. There is also a magnetic function on the back of the CO CO2 monitor, which can be attached to any metal area such as home appliances or cars.<\/li><\/ul>        <\/div>\n    <\/div>\n\n    <div class=\"aawp-product__footer\">\n\n        <div class=\"aawp-product__pricing\">\n            \n            \n            <a href=\"https:\/\/www.amazon.com\/gp\/prime\/?tag=romanceunivers-20\" title=\"Amazon Prime\" rel=\"nofollow noopener sponsored\" target=\"_blank\" class=\"aawp-check-prime\"><img decoding=\"async\" src=\"https:\/\/romanceuniversity.org\/blog\/wp-content\/plugins\/aawp\/assets\/img\/icon-check-prime.svg\" height=\"16\" width=\"55\" alt=\"Amazon Prime\" \/><\/a>        <\/div>\n\n                <a class=\"aawp-button aawp-button--buy aawp-button aawp-button--green\" href=\"https:\/\/www.amazon.com\/dp\/B0CRQZNPLV?tag=romanceunivers-20&#038;linkCode=osi&#038;th=1&#038;psc=1&#038;keywords=cheap%20co2%20sensor\" title=\"View Product\" target=\"_blank\" rel=\"nofollow noopener sponsored\">View Product<\/a>\n            <\/div>\n\n<\/div>\n\n            \n            \n<div class=\"aawp-product aawp-product--horizontal aawp-product--style-standard aawp-product--bestseller aawp-product--ribbon\"  data-aawp-product-asin=\"B08TRKL94H\" data-aawp-product-id=\"3064371\" data-aawp-tracking-id=\"romanceunivers-20\" data-aawp-product-title=\"Carbon Monoxide Detector,CO Gas Monitor Alarm Detector,CO Sensor with LED Digital Display for Home,Depot,Battery Powered\" data-aawp-geotargeting=\"true\">\n\n    <span class=\"aawp-product__ribbon aawp-product__ribbon--bestseller\">Rank No. #2<\/span>\n    <div class=\"aawp-product__thumb\">\n        <a class=\"aawp-product__image-link\"\n           href=\"https:\/\/www.amazon.com\/dp\/B08TRKL94H?tag=romanceunivers-20&linkCode=osi&th=1&psc=1&keywords=cheap%20co2%20sensor\" title=\"Carbon Monoxide Detector,CO Gas Monitor Alarm Detector,CO Sensor with LED Digital Display for Home,Depot,Battery Powered\" rel=\"nofollow noopener sponsored\" target=\"_blank\">\n            <img decoding=\"async\" class=\"aawp-product__image\" src=\"https:\/\/m.media-amazon.com\/images\/I\/314giu3g36L._SL160_.jpg\" alt=\"Carbon Monoxide Detector,CO Gas Monitor Alarm Detector,CO Sensor with LED Digital Display for Home,Depot,Battery Powered\"  \/>\n        <\/a>\n\n            <\/div>\n\n    <div class=\"aawp-product__content\">\n        <a class=\"aawp-product__title\" href=\"https:\/\/www.amazon.com\/dp\/B08TRKL94H?tag=romanceunivers-20&linkCode=osi&th=1&psc=1&keywords=cheap%20co2%20sensor\" title=\"Carbon Monoxide Detector,CO Gas Monitor Alarm Detector,CO Sensor with LED Digital Display for Home,Depot,Battery Powered\" rel=\"nofollow noopener sponsored\" target=\"_blank\">\n            Carbon Monoxide Detector,CO Gas Monitor Alarm Detector,CO Sensor with LED Digital Display for Home,Depot,Battery Powered        <\/a>\n        <div class=\"aawp-product__description\">\n            <ul><li>\u25ceThe carbon monoxide detector alarm continuous monitoring of Carbon Monoxide levels to keep your family safe.
