Carbon monoxide detection wireless Wifi connection home security system. Smart app tuya / smart life operation and alarm receiving. Battery powered wireless home security environment sensor. Packing List 1 x Carbon Monoxide alarm 1 x Mounting bracket 1 x Screw Kits 1 x User manual A carbon monoxide detector is a critical and potential life saving device that sounds and alert and send warning alarm to your mobile. It has LCD display to show the CO density. Wifi wireless connection and receive alarm on mobile in time to save life. The CO alarm detects the presence of the odourless, tasteless and colourless gas. It continuously monitors and measure the level of CO in the air. Where is the carbon monoxide mostly often produced? Blocked chimneys If chimneys are blocked, exhaust gases can no longer be sufficiently removed from the residence or house. Due to birds' nests or other garbage, the chimneys are blocked and people succumb to carbon monoxide poisoning while asleep. Fireplace, gas stove, oil and gas heating, grills Above devices run on fossil fuels such as coal, crude oil and natural gas. These gases may produce CO when they don't burn completely. Product Specifications Battery type: 9V Alkaline (can be replaced) Battery life: 3 years Sensor type: Electrochemical CO sensitivity: 50 ppm: 60-90 mins. 100 ppm: 10-40 mins. 300 ppm:
