Realization of a real-time clock in a flammable gas monitoring system with sixteen conditions by two keys

In the monitor of the conditions of flammable gases, it is required to get the current concentration instantaneously and truly. When the current concentration is above the warning value, the system can give the warning signals and current time immediately this might deal with the issue of a real-time clock. In this paper, the realization and calibration of the real-time clock of its month, day, hour, minute and second only by two keys are introduced in detail.
