The expanse switching sensor (ESS) (1) and the earning switching sensor (ERSS) (2) are activated and acting as a closed switch when a financial officer touch, pressure or force, and when the pressure or contact is removed, the ESS (1) and ERSS (2) are acting as an open switch. Further, the invention includes a capacitance measuring circuit continuously measuring capacitance (C0) of the ESS (1) and ERSS (2); and a Node MCU (3) including output pins (D2, D3) connected with the ESS (1) and ERSS (2), respectively. The information of digital output value is transmitted via the Node MCU (3) to think to speak channel.
