Proximity and light sensor
8 October 2014
Opto-Electronics
Murata announced what it believes to be the world’s smallest combined proximity and illuminance sensor. Measuring just 3,05 x 2,10 x 1,10 mm, the surface mounted LT-1PA01 uses a photoreceptor to measure the distance to an object based on the amount of returned light. Another photoreceptor is used to detect the amount of ambient brightness. The device consumes only 80 μA during proximity sensing. Its illuminance sensing angle is ±45° at 50% and sensing distance is up to 70 mm with grey card. Operating voltage is +3,3 V d.c. and communication with the host processor is via I²C serial communications.
