Abstract: The present invention relates to a toilet alarm device using an infrared sensor, which is to prevent various hidden camera crimes frequently occurring in a toilet, particularly, in a female toilet. According to the present invention, the toilet alarm device is installed at upper and lower portions of a side stall of a female toilet and blocks infrared rays radiated from a light transmitting unit of a toilet alarm device having an infrared sensor to a light receiving unit when a criminal suspect pushes the head toward an upper portion of a stall to peep into a body of a user of a next stall or pushes a camera to perform secret photographing using the camera. Also, the light receiving unit determines that intrusion occurs when the infrared rays of the light transmitting unit is not sensed, and generates an alarm light and an alarm sound, such that the criminal suspect senses danger and is induced to escape from a site. In addition, due to the alarm sound and turning-on of the alarm light, the user of the next stall can recognize a hidden camera crime in advance to take an appropriate measure, thereby preventing hidden crimes. Therefore, the toilet alarm device with an effective infrared sensor can create a toilet environment which can be more safely used by preventing various toilet accidents which may cause a hidden crime and a sexual crime.
