BH1750FVI Sensor Features BH1750FVI (or BH1750) is a calibrated digital light sensor IC that measures the incident light intensity and converts it into a 16-bit digital number. The BH1750FVI sensor directly gives digital output. The sensor output can be accessed through an I2C interface. It can measure ambient light intensity and the measurement unit is Lux. Interfacing this module with Arduino is quite easy. You can download the datasheet of this module here. [wpdm_package id='17132'] BH1750 ...

TCS3414CS Color Sensor Features TCS3414CS digital color sensor is based on TCS3414CS chip. It is designed to accurately derive the color chromaticity and illuminance (intensity) of ambient light. TCS3414CS color sensor provides a digital output I2C with 400kH speed. This sensor is able to detect different light spectra with high accuracy and speed. Note This module can’t detect the color of objects. It can only detect the reflected light spectra of objects. The higher the value of reflected l...

TCRT5000 Sensor Features The TCRT5000 Sensor is used to detect color and distance. The sensor emits an infrared wave and then receives it. TCRT5000 Infrared Reflective Sensor Module is often used in line following robots and object sorting Robots since this module can sense if a surface is white or black. The measuring distances range from 1mm to 8mm and the central point is about 2.5mm. There is also an onboard potentiometer to adjust the sensitivity. TCRT5000 Sensor Pinout This sensor has ...

Rain Drop Sensor Features The raindrop sensor module is used for rain detection. The module includes two parts. The first part is a printed circuit board that has a network of copper paths. When rain drops fall on this board, some parts of copper paths are connected to each other and the overall resistance of the board is reduced. The second part is a board converting analog output to digital output. The sensitivity of the sensor can be adjusted using the potentiometer on the board. Tip The raindrop sensor...

TCS230 Color Sensor Features The TCS230 chip reads an 8x8 array of photodiodes and uses them to recognize color. Sixteen photodiodes have blue filters, 16 photodiodes have green filters, 16 photodiodes have red filters, and 16 photodiodes are clear with no filters.The TCS230 module has 4 white LED. Photodiodes receive the light reflection of these LEDs from the surface of the object and generate an electric current depending on the color they receive.In addition to photodiodes, this sensor also has a cu...

TEMT6000 Sensor Features The TEMT6000 sensor is an analog sensor which has a function similar to NPN transistor. The sensor is designed to mainly detect the light spectrum visible to the human eye with peak sensitivity. If the light intensity increases or decreases, it will react properly. This sensor is too sensitive and react to slightest changes in a wide brightness range. Note This sensor does not react well to IR and UV light. You can download the datasheet of this sensor here.  [wpdm_...
