Status:
IR Eclipse Click is a compact add-on board that adds photo interrupter ability to any application. This board features the EE-SX198, a transmissive photomicrosensor with a phototransistor output from Omron. This compact interrupter sensor senses objects or object positions with an optical beam. It can sense any object less than 3mm as it is the space between the photomicrosensor and phototransistor in which an object can fit. This Click board™ makes the perfect solution for printers, copiers, vending machines, and other applications requiring photo interrupter ability, detecting a moving part, or even a rotation speed.
IR Eclipse Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.

Availability date:
IR Eclipse Click is based on the EE-SX198, a transmissive photomicrosensor with a phototransistor output from Omron. It consists of one infrared transmitter and receiver facing each other and spaced apart by a 3mm slit. The sensor activates when an object in the gap, such as a piece of paper, eclipses the transmitter beam. The object intercepts the optical beam of the emitter, thus reducing the amount of the optical energy reaching the detector. Some smaller objects do not fully intercept the optical beam emitted by LED; therefore, some parts of the beam come to the detector and allow current flow from the phototransistor (considered noise).
The IR Eclipse Click communicates with the host MCU using only the INT line of the mikroBUS™ socket. The INT pin provides information to the MCU about the presence of an object in the gap and about the sensor's activity. Also, the INT LED serves as a visual indicator of the activated sensor.
This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the LOGIC LEVEL jumper. This way, both 3.3V and 5V capable MCUs can use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.

We provide a library for the Ir Eclipse Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Package can be downloaded/installed directly from NECTO Studio Package Manager (recommended), downloaded from our LibStock™ or found on Mikroe github account.
Library Description
This library contains API for Ir Eclipse Click driver.
Key functions
Example Description
This is an example of IR ECLIPSE click board.
void application_task ( void )
{
state_new = ireclipse_int_status( &ireclipse );
if ( ( state_new == IRECLIPSE_HIGH ) && ( state_old == IRECLIPSE_LOW ) )
{
state_old = IRECLIPSE_HIGH;
log_printf( &logger, " Counter = %d rn", n_cnt );
n_cnt++;
}
if ( ( state_new == IRECLIPSE_LOW ) && ( state_old == IRECLIPSE_HIGH ) )
{
log_printf( &logger, "--------------------rn" );
state_old = IRECLIPSE_LOW;
}
}
The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager (recommended), downloaded from our LibStock™ or found on Mikroe github account.

Additional notes and informations
Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. A UART terminal is available in all MikroElektronika compilers.
This Click board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
