WIRELESS SENSOR SYSTEM
First Claim
1. A wireless sensor system comprising:
- a first wireless sensor configured to be driven by a battery;
a wireless device; and
a magnetic field generator connected to the wireless device,wherein the first wireless sensor includes;
an ambience sensor that detects a status of an ambient environment to output ambient data depending on the detected status of the ambient environment;
a magnetic sensor that receives electric power supplied from the battery to sense a magnetic field;
a radio-frequency (RF) transmitter that receives electric power supplied from the battery to send the ambient data to the wireless device with using a radio wave; and
a first controller that receives electric power supplied from the battery and that is connected to the ambience sensor, the magnetic sensor, and the RF transmitter,wherein the wireless device includes;
an RF receiver that receives the radio wave sent from the RF transmitter; and
a second controller that is connected to the RF receiver and that outputs a first control signal for controlling the first controller, andwherein the magnetic field generator includes a first coil for sending the first control signal to the first magnetic sensor with using a magnetic field.

Abstract
A wireless sensor system includes a wireless sensor, a wireless device, and a magnetic field generator connected to the wireless device. The wireless sensor includes an ambience sensor that detects status of an ambient environment to output ambient data depending on the detected status of the ambient environment, a magnetic sensor that senses a magnetic field, a radio-frequency (RF) transmitter that sends the ambient data to the wireless device using a radio wave, and a first controller that is connected to the ambience sensor, the magnetic sensor, and the RF transmitter. The wireless device includes an RF receiver that receives the radio wave sent from the RF transmitter; and a second controller that is connected to the RF receiver and that outputs a control signal for controlling the first controller. The magnetic field generator includes a coil for sending the control signal to the magnetic sensor using a magnetic field.
