Photocell : Types, Circuit, Working and Its Applications
In the lighter scenario, the photocell resistance is maximum and the current flow direction gets modified. So, at the transistor base, there will be minimum resistance. When the transistor''s base terminal receives power, then it operates such as conductor and the path that consists of a resistor, LED1 and transistor will be in OFF state and LED …

Fundamentals of Photoelectric Sensors
The sensing range is fixed and defined as the focus point. The sensor is then able to detect an object at this focal point, plus or minus some distance, known as the "sensing window". Objects in front of or behind this sensing window are ignored. The sensing window is dependent on the target''s reflectivity and the sensitivity adjustment.

Photocell Basics: Photocells are also called by many other names including photoconductive cells, light-dependent resistors (LDR''s), and photoresistors. They are variable resistors with an extremely wide range of resistance values (up to hundreds of orders of magnitude) that are dependent on the level of incident light.
Photodiodes and other Light Sensors
The best way to measure a range of photocell outputs accurately is with an analog interface circuit, either using an operational amplifier, or driving a suitable analog-digital converter (ADC) directly from a photocell.
How to Wire a Photocell to Multiple Lights?
The terms "photocell" and "photoelectric cell" are often used interchangeably to refer to the same light-sensitive device, such as a cadmium sulfide (CdS) photocell. Both terms describe a semiconductor component that changes its resistance or conductivity based on changes in light intensity.
