Automating HACCP temperature records | Starting IoT with one refrigerator
Aitsu-in column materials
It's okay to switch from daily handwritten temperature records to automatic recording.
Standing in front of the refrigerator, I check the thermometer and write it down on the recording sheet. Forgetting to fill it out, summarizing later, and not noticing abnormalities during the night or on holidays are all burdens and risks associated with handwritten temperature records. HACCP records are also allowed to be stored as electronic data (automatic recording). However, there are specific considerations for refrigerators and freezers, such as difficulty receiving signals, batteries depleting quickly in low temperatures, and wiring potentially causing condensation. This document explains the automation mechanism, specific considerations for freezers, cost estimates, and five steps to start small with just one unit. It clearly states what can and cannot be done with the system, and for areas where it cannot be applied, we introduce reliable specialized companies. *For more details, please download the PDF or feel free to contact us.*

Price information
The materials can be downloaded for free. The cost of sensor installation will be individually estimated based on the number of refrigerators and freezers and the installation environment.
Delivery Time
※First, we recommend starting with a trial of one refrigerator. After confirming the signal conditions at the site, we will suggest how to proceed.
Applications/Examples of results
【In such a situation】 - The temperatures of the refrigerator and freezer are recorded by hand every day. - If the freezer stops at night or on holidays, it goes unnoticed. - There is a lot of effort involved in storing records and organizing documents before audits. - I want to manage temperature records along with data from other equipment. 【Flow of utilization (example)】 1. Select one refrigerator or freezer that has a heavy recording burden. 2. Check on-site whether the signal can reach and where to place the sensor. 3. For 1 to 2 weeks, run it in parallel with paper records to verify the values match. 4. Decide who will be notified in case of abnormalities and what actions they will take. 5. If there are no issues, expand to other refrigerators.
