Last Mile Delivery

   Last Mile delivery is the last stage of logistics industry right before reaching customers. These days temperatures are managed by paper in last mile stage so it comes out limitation for managing low-temperature supply chain management, cold chain. Real time temperature monitoring system of CheckLOD has advantage of this limitation for sending real data to customers and business partners to enhance credibility.

Data Transmission

   Measured temperature data in the package by external probe is transmitted by BLE 4.0 signal from CheckLOD logger to application on mobile which locates with the driver. Application draw the graph and forward received data from logger to the cloud server with GSP location information of mobile. Forwarded data to the server can be easily checked any environment with internet connection also CheckLOD website offers PDF convert service for reporting.

CheckLOD logger

      CheckLOD logger send measured temperature data to the mobile. Measuring temperature range may vary by the limitation of probes. Measured temperature will transmit to mobile periodically by 30 seconds, a minute or five minutes. Transmission is based on BLE 4.0 signals and the distance is approximately 10 meters it can penetrate steel wall. Humidity is also transmitted with temperature data at the same time. CheckLOD logger can store datas when it locates far away from mobile such as cargo shipment and train shipment. This logger is certificated by KOLAS from South Korean government which satisfy ISO/IEC 17011. Since certification will be validated a year, new device with new certification will be replaced certification expired device. Attached probe makes each internal package temperature measurable while the logger locates outside of the package. This increase the accuracy of the temperature variation.
