Semiconductor O3 Sensor ZQ02
Summary:
ZQ02-O3 adopts thick film semiconductor sensor, it has the basic function of household ozone concentration exceeding alarm; provides status indication, switching signal outputs by buzzer and supports the reset of alarm value.
Feature:
*Good sensitivity and quick response to ozone
*long lifespan
*low cost
*simple drive circuit
APPLICATION
The combustible gas alarm is an alarm device for detecting gas leakage. The component that reacts to the combustible gas is a gas sensor, and the response signal is converted into an electrical signal through the circuit board. When the combustible gas in the air reaches a certain concentration value, the alarm will alarm. The high-end household combustible gas alarm can automatically start the exhaust equipment and close the gas pipeline valve at the same time. A wireless transmission device can be installed inside the gas alarm to realize overall monitoring and network alarm to ensure the safety of everyone's life and property.
