Embodiment approach

[0009] As an embodiment of the present invention, see figure 1 , The present invention includes a microcontroller, a power module connected to the microcontroller, and a gas concentration sensor, and also includes an LED light, a buzzer, and a reset switch. The gas concentration sensor is connected to the A / D port of the microcontroller, and the LED The lamp is connected to the I / O port of the microcontroller, the buzzer is connected to the I / O port of the microcontroller, and the reset switch is connected to the I / O port of the microcontroller, which is an AT89S2051 microcontroller.

[0010] If there is a gas leak, the gas concentration sensor is connected to the A / D port of the microcontroller. When it detects that the gas concentration reaches a certain level, the microcontroller will simultaneously drive the buzzer and the LED light to act as a double alarm Function: After people stop the gas leak, they can press the reset switch to reset and return to normal work. The microc...

Abstract

The invention discloses a household gas concentration alarm device. The device comprises a microcontroller, and a power supply module and a gas concentration sensor which are connected with the microcontroller. The device further comprises an LED lamp, a buzzer, and a reset switch. The gas concentration sensor is connected with an A / D port of the microcontroller. The LED lamp is connected with an I / O port of the microcontroller. The buzzer is connected with another I / O port of the microcontroller. The reset switch is connected with still another I / O port of the microcontroller. The household gas concentration alarm device has a simple structure and is convenient and practical. The gas concentration sensor is connected with the A / D port of the microcontroller. When the concentration of gas reaches a certain extend according to the detection, the microcontroller simultaneously drives the buzzer and the LED lamp to achieve a double alarm effect. After the gas leakage is stopped, the reset switch can be pressed for resetting.

Description

Technical field [0001] The invention relates to an alarm device, in particular to a household gas concentration alarm device. Background technique [0002] In our daily life, many families use gas.
