High development load Software development for image processing is required when converting colors, and software modification fees are also required when changing or adding colors. |
Over configuration An MPU with high processing power is required to process camera image data. |
Huge communication fees The amount of communication required to send image data to the host is enormous, and communication methods are limited. |
Color Sensor ![]() |
Low development load No application development is required because the RGB voltage corresponding to the color is output from the sensor when converting colors. |
Optimal configuration Because the sensor handles RGB output voltages, processing by an inexpensive MPU is possible. |
Minor communication fees The sensor separates color into RGB and outputs only the RGB output voltage data, so color detection can be performed with a small amount of communication. |
This color sensor is small and can be easily integrated into equipment.
- Power-supply voltage: 5 V ±5%
- Digital output: A/D conversion not required on the product side
- Communication method: I2C
- Can be mounted from two directions with M3 screws
