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. 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?
   After 24-48 hours:
4. Contact support
5. Provide Sensor SN(s) used in test
