Subject: [EE] Looking for Laser Detector Component This particular laser detector module is sold many places online but I=20 can't find the 3 terminal laser sensor itself. Does anyone know what the=20 part would be and where I can find it's specs. On this board it takes 5=20 volts and ground and outputs a signal when a laser signal is received. I=20 am thinking it is just a phototransistor of some kind but I would like=20 to know which one. It claims to be optimized for 650 nM. Here is a link=20 to it. https://www.amazon.com/Icstation-5V-Laser-Sensor-Module/dp/B 01M8PFZRC/ref=3Dcm_cr_arp_d_product_top?ie=3DUTF8 Thanks, Jim --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
