Customer Questions & Answers

What supply voltages and logic levels is the sensor compatible with, and how do you connect it to an Arduino board?

The sensor operates from a 3.3 V or 5 V supply and supports logic levels from 1.8 V to 5 V for the I2C interface. It connects via the SDA and SCL pins to the corresponding Arduino pins. External pull-up resistors are not required on most commercial boards.

What are the minimum and maximum sensitivity of the sensor, and up to what brightness range can it measure accurately?

The TCS34725 offers a dynamic range of 3,800,000:1 thanks to its adjustable gain and integration time. It can detect light levels from less than 0.1 lux up to approximately 10,000 lux with accuracy. For values outside that range, linearity may decrease.

Are there compatible and reliable libraries for use with Arduino, and how is a basic colour calibration carried out?

Yes, there are stable libraries such as Adafruit_TCS34725 for Arduino, which simplify integration and data handling. For basic calibration, it is recommended to measure known reference colours and apply correction factors to the detected RGB values to compensate for environmental or material-related deviations.

Is the TCS34725 sensor compatible with Arduino boards?

Yes, the TCS34725 sensor is designed to integrate easily with Arduino boards via a compatible I2C interface.

What colours can this sensor detect?

The sensor detects red, green, blue (RGB) and white light, with an IR filter for greater colour measurement accuracy.

What applications is this sensor ideal for?

It is ideal for RGB LED backlight control, colour temperature measurement, ambient light detection, fluid analysis and product sorting by colour.

What advantages does the integrated IR filter offer?

The IR filter blocks infrared light to prevent interference, allowing more accurate and true-to-life colour measurements, similar to human perception.

What is the sensor's power consumption?

The sensor has low power consumption with a standby current of 2.5 uA and programmable sleep modes to optimise energy use.
