PURPOSE: An intrusion sensor is provided to reduce malfunction and enhance operation reliability by including a microwave module and a thermal image module together. CONSTITUTION: An intrusion sensor comprises a microwave module(110), a thermal image module(120), and a microcontroller(130). The microwave module irradiates a microwave signal to a monitoring region and detects an intruder by a reflective signal. The thermal image module measures absolute temperature about the monitoring region and creates a thermal image. The microcontroller determines the intruder invades when receiving a signal corresponding to intrusion from the microwave module and the thermal image module in the monitoring region. |
