Abstract

The invention discloses a low-consumption sound-light alarm circuit which comprises a first 555-type time-base integrated chip, a second 555-type time-base integrated chip, a first resistor, a second resistor, a third resistor, a fourth resistor, a fifth resistor, a sixth resistor, a seventh resistor, a first capacitor, a second capacitor, a third capacitor, a first diode, a second diode, a third diode, a first audion, a second audion, a loudspeaker and a light source. When the low-consumption sound-light alarm circuit adopts the two 555-type time-base integrated chips and a peripheral configuration circuit to trigger alarming, the loudspeaker and the light source can send discontinuous alarm signals. The low-consumption sound-light alarm circuit is lower in structural cost and rich in functions.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a low-power acousto-optic alarm circuit. Background technique [0002] Today's home life is increasingly emphasizing safety. In some high-end residential areas, various monitoring equipment and alarm equipment are usually installed, such as infrared detection equipment, various remote cameras, etc. [0003] However, the circuits of the existing alarm devices are relatively complex and have single functions, so neither the manufacturing cost nor the alarm efficiency can meet the demand. Contents of the invention [0004] The technical problem to be solved by the present invention is to propose a low-power sound and light alarm circuit with sound alarm and light alarm in view of the above-mentioned shortcomings of the prior art. [0005] The technical solution adopted by the present invention to solve the technical problem is to propose a low-power sound-light alarm circuit, which inc...
