Hereinafter, target items such as foods, drugs, and IT parts that require low temperature management will be collectively referred to as products.

On the other hand, products such as agricultural, livestock and livestock products are supplied for school or group meals while maintaining a temperature and humidity that do not perish using a transport vehicle equipped with a cooling function. In other words, the product is placed in a packaging box so that the product is not contaminated with foreign substances, and then the packaging box is stacked in the loading box of the transfer vehicle for feeding, and then transported to the feeding place and supplied.

However, in transporting these products to the transport site, there is a need to check whether the product is properly moved under an appropriate temperature and humidity condition. Accordingly, a sensor for sensing and managing temperature and humidity is disposed in the product packaging box. At this time, the sensor disposed in the packaging box after product transfer is recovered and reused. However, since a separate fastening means is not provided in the conventional sensor, there is a problem in that the sensor is damaged or lost while moving during transportation of the packaging box.

Here, in the initial sleep mode state, when the motion detection sensor unit detects a shock or motion greater than a set value, the main body is switched to an operation mode, and power is supplied to the temperature/humidity sensor unit and the proximity sensor unit from the power supply unit according to a reference period. It detects the temperature and humidity and transmits the temperature and humidity information detected by the external data collector through the wireless communication unit, and the proximity sensor unit determines whether or not the product is placed inside the product packaging box, so that the product is not detected or the motion is detected. When the sensor unit detects no impact or movement over a set value for a predetermined period of time, it is switched to a sleep mode, and the power supply from the power unit to the temperature/humidity sensor unit may be cut off.

In addition, if the temperature/humidity change detected by the temperature/humidity sensor unit is within the set value, the reference period is randomly adjusted and gradually longer to reduce the sensor tag energy to detect the temperature and humidity, and if the temperature/humidity change exceeds the set value, the reference period is gradually gradually increased. It can be controlled to sense temperature and humidity by adjusting it to shorter.

In addition, the fastening protrusion may be provided with a detachable awl member for drilling a hole for penetrating the fastening protrusion in the box when mounted on the product packaging box.

According to the present invention, the sensor tag is provided with a fastening means for fastening to the product packaging box and is securely fixed to the packaging box, thereby preventing damage or loss, thereby reducing maintenance costs.

In addition, a proximity sensor unit and a motion detection sensor unit are provided on the sensor tag, and the proximity sensor unit determines whether or not a product is placed inside the packaging box, so that the product is not detected or the motion detection sensor unit exceeds the set value for a certain period of time. When no impact or movement is detected, energy can be saved by switching to sleep mode.

In addition, by providing an awl member in the fastening protrusion, the sensor tag can be more conveniently installed in the packing box by easily forming a hole for through the fastening protrusion in the packing box.
