Table 3 HOBO MX2302A External Temperature/RH Sensor Data Logger, technical information.
From: Year-round hourly temperature and humidity sensor readings from arid caves, Judean Desert, Israel
Temperature Sensor | |
|---|---|
Range | External temperature sensor: −40 to 70 °C |
Accuracy | ±0.25 °C from −40 to 0 °C ±0.2 °C from 0 to 70 °C |
Resolution | 0.02 °C |
Drift | <0.01 °C per year |
Relative Humidity Sensor | |
Range | 0 to 100% RH, −40 to 70 °C; exposure to conditions below −20 °C or above 95% RH may temporarily increase the maximum RH sensor error by an additional 1% |
Accuracy | ±2.5% from 10% to 90% (typical) to a maximum of ±3.5% including hysteresis at 25 °C; below 10% RH and above 90% RH ±5% typical |
Resolution | 0.01% |
Drift | < 1% per year |
