Z Sensor: Temperature Reading is a Few Degrees Warmer or Colder than Expected
Check Sensor Position
If the sensor is positioned near the exhaust fan or near a cold air fan. Micro-climates can cause inaccurate readings. Our sensors are rated to be within ±0.5°C (±0.9°F) and can be NIST/ISO certified by an accredited lab to ensure this reading accuracy.
Comparing Against Our Sensors
When comparing the temperature readings from our sensors to another thermometer or data logger, it's important to be mindful of the following:
1. The margin of error of the comparison tool: Many thermostats will have a much higher margin of error than our sensors, ±0.5°C (±0.9°F).
2. The temperature gradient of the room, refrigerator, or any other placement is in three dimensions: Measuring the temperature in one part of the location can yield different results than in another part of the same location due to micro-climates.
3. Air temperature changes faster than the temperature of a large amount of liquid: Air temperature in a refrigerator may rise dramatically when the door is opened, but the temperature of the contents of the refrigerator will rise more slowly due to their increased thermal mass. We recommend the use of a buffer vial (virtual or physical) to ensure proper readings are obtained at all times.
4. IR guns measure surface temperature while our sensors measure ambient air temperature or buffered temperatures.
