The MM109 Light sensor module from Velleman. Based on Vishay’s TEMT600
detector, this breakout board is intended or those who need to test or
integrate a detection system for the lighting environment. The TEMT6000
is a silicon NPN phototransistor, in a SMD execution, whose contacts’
arrangement is consistent with the one adopted by many modern
components: no pins, but L-shaped contacts that start from the side and
go on under the body. The phototransistor is sensitive to the light’s
visible spectrum; the sensitivity is guaranteed within a ± 60° angle,
with respect to the perpendicular line to the said surface.
