An indication of sensor temperature being too low results in a degradation of
image quality and inexact temperature measurement. In case that this control
output does not become inactive after some minutes of operation, the ambient
air temperature of the camera might be too low.
To resolve this, heat up the camera temperature above approx.
15 °C
(
Pearleye
P-030 LWIR
) or
25 °C
(
Pearleye P-007 LWIR
). Use for e.g. a temperature-
controlled air-flow housing.
Sensor temperature too high (pin 14)
An indication of sensor temperature being too high results in a degradation of
image quality and inexact temperature measurement.
In case that this control output is permanently active already after some min-
utes of operation, the environment temperature of the camera might be too
high. A sufficient cooling of the camera is obligatory.
Pearleye P-007 LWIR
For ideal results the camera housing temperature should be lower than
45°C
.
Pearleye P-030 LWIR
For ideal results the camera housing temperature should be lower than
35°C
.
