Electromechanical shutter (I)
The
Pearleye P-007 LWIR
/
Pearleye P-030 LWIR
models are equipped with an
electromechanical shutter that can be controlled with the command
I
.
Use
I=1
to close and
I=0
to open the shutter.
Temperature warning (T)
The command
T=1
displays the content of the temperature warning register. The
lowest order bit has the same function as LED L3 placed at the backside of the
camera housing. In case the value 1 is output, the temperature of the microbo-
lometer sensor is outside the optimum range. After switching on the camera you
have to wait some time until the set value is reached. In case that the tempera-
ture warning remains active for a longer period, the environment temperature
of the camera should be checked.
The camera is equipped with an internal temperature sensor. The temperature
can be displayed using the command
T=2
. The temperature is output as 16-bit
value. The 4 most significant bits contain information about the temperature
sensing state. The remaining 12 bits contain two’s complement of 1/16 degrees
Celsius.
Note
The shutter is open by default (power off).
The typical life time of the electromechanical shutter is:
1 million control cycles.
