Further, signal amplification circuit 35 is connected between gas sensor 31 and main control chip 33, thus by gas
Sensor 31 detects obtained response signal and sends main control chip 33 to after the amplification of signal amplification circuit 35.
Since the testing result of 31 detection gas concentration of gas sensor can be affected by temperature, in some instances,
Gas detection module 30 further includes temperature sensing circuit 36, and temperature sensing circuit 36 is connected to power-switching circuit 32 and master control core
Between piece 33, temperature sensing circuit 36 can carry out temperature-compensating to the testing result of under test gas, exclude temperature and examined to gas
The influence of survey, to ensure the accuracy of result of detection.
For example, thermo-sensitive resistor may be used in temperature sensing circuit 36, it is to be understood that in the case of temperature difference,
Preset gas concentration value is not exactly the same in main control chip 35, therefore the gas concentration that gas sensor 31 detects is by letter
Send main control chip 35 after the amplification of number amplifying circuit 35 to, main control chip 35 acquires the temperature signal of thermo-sensitive resistor simultaneously, right
Gasmetry result carries out temperature-compensating, so that it is guaranteed that under test gas concentration is accurate.
An example according to the present utility model, power plug arrangement 100 further include reminding module 37, reminding module 37 with
Main control chip 33 communicates, so as to be sent out when gas detection module 30 detects that under test gas concentration is more than the default density
Standby signal is outwardly alarmed, and the compatibility of power plug arrangement 100 is further improved.
In some instances, reminding module 37 can be audible alarm unit and/or light warning device, work as gas detection
When module 30 detects that under test gas concentration is more than the default density, reminding module 37 makes a sound warning message and/or light
Warning message can timely found the abnormal situation thereby using family, avoid generating unnecessary loss.
Include the combustion according to above-described embodiment according to the gas-fired equipment (not shown) of the utility model embodiment
The power plug arrangement 100 of gas equipment.
