WARNING: This sensor is sensitive to over-exposure (objects above 150
o
C); the sensor
is considered “sun-safe” in the sense that pixels will not break if over exposed for short
periods; however, long exposure to hot bodies (like the sun) will eventually create a
ghost-like artifact that can take as much as 48h to dissipate depending on the
temperature of the object and time of exposure.
