CMOS integrated optical sensor Converts light intensity into voltage Chip integrates transimpedance amplifier and output transistor Highly linear output 3.3V or 5V power supply
Ambient click carries the Melexis MLX75305 IC. It's a CMOS integrated optical sensor that consists of a photodiode, a transimpedance amplifier, and an output transistor. The chip converts ambient light intensity into a voltage, using the mikroBUS AN pin for communicating with your target board's MCU.
Ambient light sensors are widely used in portable devices with screens, in order to automatically adjust backlight depending on how bright the surrounding is. If the screen is outdoors in sunlight, brightness is amped up to max, if it's inside and dark, brightness is lowered to reduce eyestrain and conserve battery life. Smart home projects are another possibility, having lights turn on and off automatically based on the amount of ambient light.
Basically, ambient light sensors are applicable wherever useful data can be deduced from the presence or absence of light. You can tell if something, any sort of object, is in the right place based on whether it casts a shadow over the sensor (e.g. a piece of paper inside a printer).
This board can use 3.3V or 5V power supply, determined by setting a solder jumper (in 3.3V position by default).
Note: The picture shows the board with through-hole headers. The board now comes populated with male pin headers already soldered for your convenience. The board's user manual has yet to be updated to remove the soldering instructions.
mikroBUS Click Boards Overview Click boards plug directly into a mikroBUS socket. mikroBUS is a specially designed plug-and-play pinout standard. The sockets are found on Clicker boards, the Flip & Click Arduino/Python-compatible board, the Quail board, these mikromedia shields, the Microchip Curiosity board, and development systems from mikroElektronika (V7 systems and later).
You also can connect Click boards to many other popular platforms via these adapters:
- PC — Click USB Adapter (MIKROE-1433)
- Arduino — Arduino UNO click shield (MIKROE-1581) or Arduino Mega click shield (MIKROE-1900)
- Raspberry Pi — Pi click shield (MIKROE-1512) or Pi 2 click shield (MIKROE-1879)
- BeagleBone Black — BeagleBone click shield (MIKROE-1596) or mikroBUS Cape (MIKROE-1857)
- STM32F3 Discovery — STM32F3 Discovery Shield (MIKROE-1447)
- STM32F4 Discovery — STM32F4 Discovery Shield (MIKROE-1481)
- Stellaris LM4F120 LaunchPad / Tiva TM4C123G LaunchPad — Click BOOSTER PACK (MIKROE-1363)
- Freescale Freedom — FRDM-KL46Z click shield (MIKROE-1795) or FRDM-K64F click shield (MIKROE-1794)
In addition, it is royalty-free to add mikroBUS to your own designs. Visit the mikroBUS Category to see the full line of Click boards.
