Domestic environment monitor

The invention relates to a domestic environment monitor. An FPGA master control module respectively communicates with a power supply module, a measurement module, a control and alarming module, a communication module and a display module, wherein the measurement module is connected with the sensor module; the display module is connected with a display; the control and alarming module is respectively connected with a parameter adjusting module and a power amplifier; and the sensor module comprises a temperature and humidity sensor, a PM2.5 sensor, a carbon dioxide sensor, a formaldehyde sensor and a radioactive sensor which are arranged on the measurement module in a parallel connection manner. The domestic environment monitor can automatically monitor various parameters of an indoor environment, the various parameters are transmitted to a head of a household through the communication module, the power amplifier gives an alarm when parameter indexes of the indoor environment exceeds a set threshold value, cont
