Applications of Combustible Gas and CO Sensors in Smart Homes

20180528111441

Nowadays, sensors have been integrated into everywhere of our life. They analyze users` daily behaviors and enrich users` interaction channels with their circumstances. Some smart sensors, like motion sensors and temperature & humidity sensors, enhance the safety and convenience of our life significantly.

Sensors are essential in designs and solutions of popular smart home appliances like air purifiers and toxic gas detectors.

Noxious gas sensor — Toxic gas detection solutions

CO poisoning and combustible gas leakage pose great threat to people`s health and safety, so corresponding sensors are used to detect the presence of noxious gas and safeguard the family. Once noxious gas is detected, alarms will be triggered. Ventilation fans or windows can also be interconnected with the sensors and react as soon as harmful gas presents.

Solution introduction: This toxic gas detection solution is based on CO detection. It measures ambient CO concentration, and reads gas level, peak value as well as High & Low alarm level. When the gas concentration exceeds the preset limited value, sound or light alarms will be activated to remind the users.

Solution of combustible gas detection is based on detection of natural gas and LPG. In kitchens, if natural gas or LPG leaks and reaches lower explosive limit, an explosion will take place with just an electric spark. In order to prevent such disaster, combustible gas sensors can be applied to monitor gas concentration in real-time, and make alarms when it reaches a certain level, so that family members can take actions in advance.
