Pull-up resistors are used in electronic logic circuits to ensure that inputs to logic systems settle at expected logic levels, if external devices are disconnected or high-impedance is introduced. They may also be used at the interface between two different types of logic devices, possibly operating at different power supply voltages.A pull-up resistor weakly "pulls" the voltage of the wire it is connected to towards its voltage source level when the other components on the line are inactive.

The basic piezo sensor can be used in anti-theft deices, electronic locks, mechanical equipment vibration detection, sound gesture application and detection range bull’s e-eye counts vibration testing occasions. The vibration levels can be supplied to any controllers/processors/ and necessary decisions can be obtained as required though it. This module has triple output mode i.e. – digital output – is simple, analog output which is more accurate and serial output with exact readings.
