Principle Introduction
| Musktool-MIX2111A domestic usage gas alarm module adopts integrated design concept, built-in advanced semiconductor gas sensor, with fault alarm, standby output, alarm output, etc. functions. The module has small size, low power consumption, long life and low cost. It also has extremely high sensitivity to domestic natural gas, LPG and other combustible gases. After aging, debugging, and calibration, it cooperates with highly integrated MCU to perform data processing operations. It greatly reduces the difficulty of developing gas alarms and facilitates rapid development or modular design of alarm products. Users only need to add a power module, LED alarm indicator, buzzer and casing to form a complete household gas alarm. |
