| titleOfInvention | A kind of indoor formaldehyde content alarming device |
| abstract | For indoor formaldehyde content is exceeded may be to the injury that body is brought, the utility model provides a kind of indoor formaldehyde content alarming device, belongs to electronic technology field.The circuit of device includes formaldehyde sensor, voltage comparator, potentiometer, light emitting diode, resistance and diode.Formaldehyde sensor is responsible for concentration of formaldehyde detection, if formaldehyde in air content is 0ppm, formaldehyde sensor output voltage is that 0.5V voltage comparators U3 exports high level, and green LED D3 lights；If formaldehyde in air content is no more than 0.1ppm, formaldehyde sensor output voltage is between 0.5V~1.2V, and voltage comparator U2 output high level, yellow light-emitting diode D2 lights；If formaldehyde in air content reaches more than 0.1ppm, formaldehyde sensor output voltage is between 1.2V~2.5V, and voltage comparator U1 output high level, red light emitting diodes light.Therefore, the present apparatus is detected applied to indoor formaldehyde content, user can be helped to understand indoor formaldehyde content in time, can effectively avoid formaldehyde may be to the harm that body is brought. |
