My Sensor monitoring data is inaccurate, what should I do?

Environmental Impacts on Temperature Sensor Accuracy

Refrigerator/Freezer Applications (Low-Temperature Environments)

Common factors affecting your temperature sensor readings in cold environments:

1. Auto Defrost Cycle
   

   If your sensor shows periodic temperature spikes (sudden increases) followed by a return to normal levels within minutes or hours, this likely corresponds to your appliance's auto defrost cycle.
   (Auto Defrost Function: Appliances with this feature activate heating elements during defrosting, causing brief ambient temperature increases. Temperatures rapidly stabilize after defrost completion.)

2. Compressor Cycling
   

   If sensor readings show consistent fluctuations with a "sawtooth" pattern on historical graphs, this typically aligns with your refrigerator/freezer's normal compressor operation.
   (Refrigeration Cycle: Cooling systems periodically activate to maintain low temperatures. Compressor operation generates temporary heat, causing slight temperature rises. Readings normalize when the cycle completes.)

3. Irregular Fluctuations
   

   For some irregular fluctuations, they may be caused by external factors, such as fridge/freezer door opening, or fridge/freezer refrigeration system malfunction.
   (External Factors: Door openings cause temporary temperature rises due to warm air entry. System malfunctions may result in inconsistent cooling patterns, leading to abnormal temperature fluctuations that deviate from normal compressor cycling behavior.)

4. Placement Considerations

   • Near doors: Temperature fluctuations occur during openings/closings.
   • Near air vents: Direct exposure to cold airflow causes rapid temperature changes.
   • Near heating elements: Areas around defrost heaters experience temporary spikes.
   • Top/bottom placement: Thermal stratification may cause unstable readings.

Room Temperature Environments

1. Placement Factors
   Ensure sensors are positioned away from heat/cold sources (radiators, AC vents, electronics, windows) that could affect readings.

If readings remain inconsistent after verifying placement, proceed to troubleshooting steps below.

Troubleshooting Temperature Sensor Accuracy

Verification Procedure:

1. Deploy multiple identical sensors side-by-side in the same environment.
   (For models with external probes: Place probes parallel to each other)
2. Allow 24-48 hours for data collection.
3. Compare all sensors' readings during this period.

Analysis & Resolution:

1. Significant Deviation
   If any sensor shows readings consistently deviating from others by a substantial margin → Potential sensor malfunction.
2. Minor Deviation
   If variations fall within acceptable error margins → Use MOCREO Smart App's Temperature Compensation feature (±9℉) to recalibrate sensors → Achieves alignment with actual ambient temperature.
3. Uncertain Results?

Environmental Impacts on Humidity Sensor Accuracy

Refrigerator/Freezer Applications (Low-Temperature Environments)

Critical Installation Note for ST6, ST9 & LS3 Sensors:
The main sensor body is NOT waterproof.
→ Do NOT place main body directly in low-temperature/high-humidity environments.

ST9-Specific Guidance:
Only the external probe should be placed inside the refrigerator/freezer.
→ Keep main sensor body outside the appliance.

Room Temperature Environments

1. Placement Optimization

   • Install ST6 sensors in well-ventilated areas
   • Avoid direct exposure to:
     • Moisture/steam
     • Dust accumulation
     • Chemical vapors
   • Position away from heat/cold sources to minimize temperature gradient effects

2. Post-Moisture Exposure Recovery
   If temporarily exposed to high humidity:
   → Use a hair dryer on cool/low setting
   → Gently blow air across sensor ventilation holes
   → Reduces residual humidity impact on readings

Troubleshooting Humidity Sensor Accuracy

Verification Procedure:

1. Deploy multiple identical sensors side-by-side in the same environment.
   (External probe models: Position probes parallel)
2. Log data for 24-48 hours.
3. Compare all sensor readings.

Analysis & Resolution:

1. Significant Deviation
   Consistent outlier readings → Potential sensor malfunction
2. Minor Deviation (within ±5% error margin)
   → Use MOCREO Smart App Humidity Compensation (±5%) to recalibrate
   → Aligns readings with actual ambient humidity
3. Uncertain Results?
