1、 Introduction to smoke detector scheme

This smoke alarm scheme uses a single chip microcomputer and MQ-2 smoke sensor as the core design of the smoke alarm, which can achieve smoke alarm, smoke solubility display, watchdog self check of the status of the single chip microcomputer, manual emergency alarm and other functions. The smoke detector designed this time has the advantages of simple structure, stable performance, convenient use, low price, etc., and has high use value.

2、 Function introduction of smoke detector scheme

The smoke detector designed by Hengjiasheng Electronics uses NY8A051D single chip microcomputer as the main control MCU. The single chip microcomputer engineer finally completes the development of the smoke detector through program burning, functional module building and circuit design, which has the following functional characteristics:

(1) Ionic smoke alarm: when smoke enters, the internal charge balance is broken, and the detector detects the charge change and gives an alarm.

(2) Audible and visual prompt: sound alarm and light prompt will be given when smoke is detected.

(3) Smoke concentration self inspection: according to the smoke concentration value, it can intelligently determine whether to alarm to prevent false alarm.

(4) Low battery prompt: when the battery is low, a warning sound will be given every 30s, and the indicator light will flash.

The PCB structure of the smoke detector is composed of an infrared tube, a buzzer, a function control motherboard and a single chip microcomputer, and can be fully compatible with other male mold housings in the market. The Pcb structure can also be customized according to customer requirements. The final product shape can be customized by the manufacturer to meet the market demand.

The above is all about the sharing of the development of the smoke detector scheme. If you have a demand for the development of the smoke detector single-chip microcomputer scheme, you can contact us directly. We have a variety of models of single-chip computers. Hengjiasheng Electronics has been focusing on the development of the application scheme of single-chip computers for 14 years, striving to provide more innovative electronic products for the majority of manufacturers!
