(laser diode used by the author) (laser beam sender circuit diagram) Laser Beam Receiver Circuit. Forepart of this circuit section is a 5mm photoresistor (LDR).This component is used to trigger the ...

Since the laser torch can transmit light up to a distance of 500 metres, this range can be increased by orienting the phototransistor sensor properly. To avoid false triggering by sunlight, mount the ...

High-performance flexible strain sensors attached on clothing or human skin are required for potential applications in the entertainment, health monitoring, and medical care sectors. In this work, ...
