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. If 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. If the temperature warn-
ing 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.
