Emma monitors temperature 12.5 times per second like a watchdog, keeping your cargo safe. Here's when it transmits:
Normal Conditions
Sends an update every 2 hours when temperature is stable
If temperature changes by 0.5°C or more, Emma sends an update
During Rapid Temperature Changes
When temperature fluctuates a lot (like during loading/unloading), Emma uses "smart brakes" to save battery while keeping all data:
First brake: Maximum 2 messages per 3 minutes.
Second brake: Maximum 5 messages every 45 minutes. Emma saves extra readings and sends them when the brake is lifted.
Result: Messages average one every 9 minutes during rapid changes. No data is lost - Emma just times the transmissions smartly.
Example (longest wait scenario):
Situation: The temperature is dropping quickly from +10°C to -10°C in the course of 60 minutes.
Emma sends 5 times in quick succession, with 3 minutes in between each. This takes 12 minutes, and activates the second brake.
Emma continues to sample temperature every 15 minutes, stores them, and then sends two samples after 33 minutes.
Next transmission will happen after 3 minutes, if the temperature continues to fluctuate. And so on and so forth.
Bottom line: Emma constantly watches temperature and saves every reading. She sends real-time alerts when it matters and manages transmissions smartly to preserve battery—but you never lose data. From an operational perspective you will get 5 quick transmissions when temperature changes rapidly, which is ample to take corrective action when needed."
