Provided herein are an input system, a keyboard device and a locking method. The keyboard device includes a key module, a transmission interface and a processing module. The key module includes a plurality of keys. The transmission interface is used for connecting a computer. The processing module is connected to the key module and the transmission interface. The processing module receives a locking signal from the transmission interface and locks at least one key of the key module according to the locking signal making the locked key stop outputting signal to the computer, wherein the locking signal is outputted from a peripheral device connected to the computer. Accordingly, the present invention can achieve the purpose of using a peripheral device to lock and unlock the specific key of the keyboard device.

Input system, keyboard device and locking method

A sensing device can detect material depth, liquid-level, and temperature. The sensing device has a probe, a control module, a volume sensing module, a thermal sensing module, an output module, and a power module. The probe has two material electrodes connected to the volume sensing module and a thermal electrode connected to the thermal sensing module. A rated voltage is applied at the material electrodes based on radio frequency admittance. A current deviation of the material electrodes is obtained by the volume sensing module, and calculated via the control module by material characteristics to obtain a correct storage amount of material. A temperature at each material depth is correctly detected by the thermal electrode. Steel cable is used as the material of the material electrodes of the probe to detect material depth or liquid level with high impact resistant ability.
