The pressure sensor(20a) is installed in the upper part of the pressure sensing unit. If the sending unit detects pressure pressing the pressure sensor and the pressure is less than reference pressure, the detected signal is wirelessly send and a battery gets power. The receiving unit recognizes the detected signal to output alarm signal and the power is supplied to a cigar jack.
