The BH1772GLC-E2 is an advanced digital Ambient Light, IR, and UV sensor produced by ROHM Semiconductor. It uses I2C interface for communication, and is made with a 0.7mm thick package and 5 x 5 mm² footprints, giving it an ease of use that makes it suitable for many applications. The BH1772GLC-E2 has become one of ROHM Semiconductor’s most popular Optical Sensors, and it continues to be used in many applications today.

The BH1772GLC-E2, as its name implies, measures the ambient light, infrared (IR) and ultraviolet (UV) radiation in the environment and converts this into digital capabilities. It is composed of a colored optical filter deposited with a temperature-resistant high-refractive-index polymer film and a photovoltaic convertor. The optical sensor is capable of reading stimulus from a DC source to a maximum of 1 mM, allowing it to easily sense illuminance in various wavebands.

When working, BH1772GLC-E2 will detect the light intensity in the environment and output a digital value according to the light intensity in the environment. The BH1772GLC-E2 also features an integrated low-noise current amplifier and temperature compensation circuit, making it capable of providing low-noise performance with great accuracy. The integrated amplifier also enables the user to set the sensor’s output voltage level.

This Optical Sensor has many application fields, such as lighting control, light sensing, room environment monitoring, factory automation, robotic navigation, etc. In addition, BH1772GLC-E2 finds its use in number of applications such as autonomous robot navigation and outdoor environments that require accurate environment sensing. The BH1772GLC-E2 is the reliable sensor choice for making certain environments user-friendly and energy efficient. Its low power requirement makes it perfectly suitable for battery-powered applications.

Furthermore, this innovative Optical Sensor embedded various features like mode selection, interrupt functions, alarm functionality, temperature compensation and activities monitoring. Through these features, BH1772GLC-E2 enables user to set the exact detection sensitivity and configure the light detections according to the environment. Additionally, the sensor also provides dual output formats with an ‘Output Low OR’ feature. This allows users to output data according to their needs, making the BH1772GLC-E2 exceptionally flexible and suitable for various application scenarios.

Apart from that, it also features a separate interrupt output pin for power saving purposes. The interrupt output pin works to keep users informed whenever the value of light intensity reaches a pre-defined value. As the user is made aware of this situation, the remote power can then be used for other purposes.

To summarize, BH1772GLC-E2 is an incredibly versatile and reliable Ambient Light, IR and UV sensor that can be used in various applications. Its ease of use and overall flexibility makes it one of the most popular choices among other Optical Sensors. ROHM Semiconductor is continually striving to improve and update their technologies and the BH1772GLC-E2 is an excellent example of the same.
