Optical Sensors - Photodiodes

The VTP1188SH is a photodiode device designed for use in a variety of applications such as sensing light for monitoring illumination levels, or for use in robotic arm or machine vision systems. It contains an array of very sensitive photodiodes that receive the light and convert it into a current signal.

Applications

The VTP1188SH is used mainly in applications where detecting small changes in light is important, such as industrial process control, medical diagnostics, and industrial automation. Its photocell array allows it to detect small changes in illumination that can be used to regulate the brightness of a lighting system, or to detect the presence of an object. The device can also be used in robotic arms or machine vision systems as an input device to detect objects or lighting levels, which it then passes on to the system controller for further analysis.

Design and Working Principle

The VTP1188SH is designed with an array of pin-grade photodiodes and associated circuitry connected to four individual output conduits. Each photodiode is encapsulated in a plastic package and has an alignment slot for positioning the device in the exact direction of the incoming light. The photodiodes are arranged in the form of a cross-pattern, which enhances the accuracy of the device in detecting small changes in light.The working principle of the VTP1188SH is based on a simple circuit already included in the built-in circuitry. When light is incident on the photodiodes, a current proportional to the intensity of the light is generated. The output is then passed through the device’s four output conduits, which are connected to the associated circuitry.The device can be set up to detect ambient light, as well as artificial lights. This is done by adjusting the sensitivity of the device, which can be done electronically or manually. When the device detects a change in light levels, it can trigger an action within the system, such as switching on a motor, or a solenoid valve, or it can be used to detect the objects that are passing in front of it.

Conclusion

The VTP1188SH is a highly sensitive photodiode device, designed for use in a variety of applications. It is capable of detecting small changes in light, making it suitable for use in industrial process control, medical diagnostics, and industrial automation. Its simple design and working principle makes it easy to configure and use.
