ABSTRACT:
Disclosed is a device for recording a curing temperature history on precast concrete products, which is buried in a precast concrete product so as to record curing temperature and time histories during a steam curing procedure and to inform a user/inspector of recorded data, thereby controlling the quality of the steam curing concrete products. The device comprises: a socket formed in the shape of a hexahedron, including a collection chamber opened at the upper portion thereof, a hole formed through a lower portion of one side wall, and a magnet installed on another side wall and serving to operate a capsule when the capsule is inserted into the collection chamber, and to protect components of the capsule when the device is buried in a designated position of the precast concrete product to be cured; and a capsule formed in the shape of a hexahedron, accommodated in the collection chamber of the socket, and provided with a MCU (Micro Controller Unit) installed on a printed circuit board within the capsule and switched on/off by the magnet of the socket, senses a curing temperature of the precast concrete product by means of the control signal of the MCU when the device is buried in the designated position of the precast concrete product detects light with a photo sensing unit when the precast concrete product is cured, informs a user of data regarding the sensed temperature and light, and stores the data.
