Common Temperature Comparison Misconceptions

Many users experience concerns about MOCREO sensor accuracy when comparing readings with traditional thermometers or refrigerator displays in low-temperature environments (refrigerators, freezers, etc.). However, these comparisons often involve common misconceptions that we'll address below.

Why Temperature Comparisons Can Be Misleading

Traditional Thermometer vs. MOCREO Sensor Comparison

We do not recommend comparing other sensors with MOCREO sensors because different sensors have varying measurement principles, accuracy levels, and error margins. MOCREO sensors can display environmental temperature trends over time in the app, while traditional thermometers only show instantaneous values and cannot reflect temperature fluctuations over time.

Refrigerator Display vs. MOCREO Sensor Comparison

1. Different Temperature Sensor Locations

  • Refrigerator displays don't measure your sensor's location: The built-in temperature display measures temperatures near cooling coils or at designated monitoring points, not where you've placed your sensor.
  • These locations are much colder: Being close to the cooling source, these areas are significantly colder than your actual storage shelf temperature.

2. Display Temperature May Be Control Temperature, Not Average Temperature

  • Internal monitoring values: Refrigerator displays typically show internal monitoring values used to control compressor start/stop cycles, not the average temperature of the entire unit.
  • Lower for preservation: These temperatures are usually several to ten degrees lower than actual storage area temperatures to maintain proper cooling effectiveness.

3. Uneven Temperature Distribution Is Normal

  • Vertical and horizontal temperature differences: Refrigerators have top-to-bottom temperature gradients and near-vent/far-vent temperature differences.
  • Significant variations: Areas near cold air outlets or evaporators are noticeably colder than areas away from vents, causing different readings at various measurement points.

Proper Temperature Monitoring Practices

1. Optimize Sensor Probe Placement

For sensors with external probes: - Place the sensor probe in the middle shelf area of the refrigerator (5-10cm from the inner wall) - Avoid direct proximity to air outlets or evaporators - Ensure adequate air circulation around the probe - Avoid direct contact with food items (food temperature inertia can affect readings) - Consult your refrigerator manufacturer for optimal placement recommendations if uncertain

2. Same-Model Sensor Comparison Testing

If you have another sensor of the same model: - Place both sensors in the same location simultaneously - For sensors with external probes, position the probes side by side - Observe for 1-2 days and compare the data curves - Consistent curves indicate accurate readings related only to environment (probe position/refrigerator design) - Significant differences may indicate potential sensor malfunction

3. Temperature Compensation

Using the MOCREO Smart App: - If environment and sensor placement are confirmed correct, use the app's calibration feature for temperature compensation (up to ±9℉) - If multiple identical MOCREO sensors show readings within acceptable error margins during comparison testing, you can use the temperature compensation feature for further calibration
