Abstract
Disclosed is a test device. The test device according to an embodiment of the present invention is operated by a power supply unit provided to be portable, and tests a sensor device using an alternating current of a high frequency. Therefore, the portability and operation reliability of the test device are improved, and the convenience of use can be improved since a separate wire member or the like for the operation of the test device need not be provided.
Claims12
A test device comprising:
- a power source portion that supplies a direct current;
- a control portion conductively connected to the power source portion to convert the direct current into first alternating current;
- a coil portion conductively connected to the control portion to form a first magnetic field using the first alternating current;
- and
- an energization portion in electromagnetic communication with the coil portion on a first side and defining a space portion on a second side, opposite to the first side, the energization portion configured to produce a second alternating current via the first magnetic field and a second magnetic field via the second alternating current to induce a third alternating current via the second magnetic field in a harvesting coil of a sensor device when the sensor device is inserted into the space portion, wherein the third alternating current is configured to power the sensor device to measure an environmental value, the environmental value selected from the group consisting of:
- a temperature;
- a humidity;
- a dust concentration;
- and
- a pressure.
