Food-Chain Temperature Logging Guide
Log food-process and product temperatures over LoRaWAN: needle probes, hygiene SOPs, decoder fields, and when to use the cold-room design page.
Process checks versus cold rooms
Food-chain temperature logging covers process and product checks across a site. Dedicated HACCP cold room monitoring architecture lives on the cold-room solution page — do not treat this guide as that design pattern.
Use a food-contact needle probe when the question is product core or a soft matrix. Confirm stainless grade and wash-down limits on the datasheet, then follow the site hygiene SOP between checks.
Records that auditors can read
Store degrees Celsius, timestamp, device name, and probe-health. Do not average a failed probe into a compliance chart. Battery millivolts belong on the maintenance list, not in the limit column.
Paste the PS-610 decoder once. Air loggers and door contacts are separate kits if you also run cold rooms. Leak rope outside wash-down areas is not a temperature substitute.
Commercial and radio basics
Stock trials start at 100 units. Branding starts at 500. EU868 and US915 are the standard plans. Destination-market documentation is a separate quote item.
This pattern supports records. It is not a medical cold-chain qualification and does not replace calibrated reference instruments on the schedule your quality manual already requires.
Training the people who read the chart
Show operators the same units and timestamps as the paper form. A second invented limit in the IoT platform creates arguments during audits.
Teach probe-health as a hold condition. Averaging a failed probe into a batch record is worse than a missing reading.
Link cold-room architecture to the dedicated cold-room page when the site is a sealed room with door and wash-down context. Keep this guide for process and product checks across the wider plant.
Commissioning discipline
Write the measurement question before you open cartons. Confirm the regional plan on the quote. Paste only the matching decoder profile for each model.
Watch the frame counter for a full reporting interval. Name devices after rooms and tanks operators already use. Stock a spare for mounts you cannot reach without a lift.
A 100-unit stock trial proves join and decode before branding at 500 units. EU868 and US915 are standard; ask before you assume another band. Destination-market documentation is a separate pack on the purchase order.
FAQ
- Cold room or food-chain page?
- Use /solutions/cold-room for room design. Use /solutions/food-chain and this guide for process/product probes across the wider site.
- Which decoder?
- PS-610 for the needle probe. See /decoders/ps-610 for named fields.
- Does wireless logging certify HACCP?
- No. It supplies timestamped values your plan can store. Limits and corrective actions stay with the site.
- How often should probes be cleaned?
- Follow the site hygiene SOP between checks. Confirm wash-down limits on the datasheet before first use.
- Air logger or needle probe?
- Air loggers watch the room plant. Needle probes watch product core. Do not let one number stand for the other.
