Silicon photocell optical control switch circuit illuminance increases to a certain value, the light-e mitting diode will be extinguished. On the contrary, controlled switch circuit based on th e silicon photocell is realized. 5. Summary software, you can analyse characteristics of photocell; test results are consistent with the theory. After
Open Circuit Voltage Characteristic Test of Silicon Photocell. Under the condition of the Fig2 circuit, the illuminance on photocell is controlle d by illumination meter. Adjust illumination to the meter, at this time the meter readings should be 0. Open the power supply, adjust the illumination read out the voltmeter reading, and fill in table 2.
The breadboard, jumper wires, battery (9V), transistor 2N222A, photocell, resistors-22 kilo-ohm, 47 ohms, LED, and battery are the key components needed to make the circuit. The above photocell circuit works in two conditions when there is light and when it is dark.
These are mainly described as Cadmium- Sulphide photocells and constructed by light-dependent resistors and photoresistors. Also, the main usage of this sensor is in light applications like light or at dark. The cell which is used in the photocell circuit is called a transistor switched circuit.
The photocell is one kind of sensor, which can be used to allow you to sense light. The main features of photo-cell include these are very small, low-power, economical, very simple to use. Because of these reasons, these are used frequently in gadgets, toys, and appliances. These sensors are frequently referred to as Cadmium-Sulfide (CdS) cells.
The photocell used in the circuit is named as dark sensing circuit otherwise transistor switched circuit. The required components to build the circuit mainly include breadboard, jumper wires, battery-9V, transistor 2N222A, photocell, resistors-22 kilo-ohm, 47 ohms, and LED.
