# Title: Motion 4 Click Board™
## Description: How Does The Motion 4 Click Board™ Work? The Motion 4 Click Board™ is using a PIR sensor that can detect changes in the amount of infrared radiation impinging upon it, which varies depending on the temperature and surface characteristics of the objects in front of the sensor. Detection performance of EKMC1603111 at ambient temperature of 25°C with temperature difference higher than 4°C is up to 12m. Angle detection area with 92 detection zones is 102°（±51°）horizontal and 92°（±46°）vertical. Output from PIR sensor is feed into buffer and then photo relay allowing users to directly control with galvanic isolation from sensor and MCU electronic devices such as lights, motors, gates etc. The TLP241A photo relay is able to effectively replace traditionally used mechanical relays, bringing up the full set of inherited benefits: virtually unlimited number of cycles since there are no moving parts that would wear off, no bouncing effect on the output contacts, high resistance to mechanical shock and environmental influence, low current required for the activation, constant resistance since no carbon and rust can build up on contacts, there is no sparking or electric arc forming while operated, compact size, higher isolation voltage, and so on. When an object, such as a person, passes in front of the background, such as a wall, the temperature at that point in the sensor's field of view will rise from room temperature to body temperature, and then back again. The sensor converts the resulting change in the incoming infrared radiation into a change in the output voltage, and this triggers the detection. Objects of similar temperature but different surface characteristics may also have a different infrared emission pattern, and thus moving them with respect to the background may trigger the detector as well. In some cases, going back and forth towards the sensor (parallel movement to the axis Z), may not be detected. Difficulty in sensing the heat source is that glass, acrylic or similar materials standing between the target and the sensor may not allow a correct transmission of infrared rays and also non-movement or quick movements of the heat source inside the detection area.

- amazon_short_description: The Motion 4 Click Board™ is a long distance PaPIR's motion sensor with plastic lense and controllable output. This Click board features EKMC1603111, a PIR motion sensor from Panasonic Corporation which can be used as human motion detector and is able to detect movement up to 12m with 170uA current consumption. Also featured on Motion 4 Click bord is TLP241A photorelay from Toshiba that is used to provide a reinforced galvanic isolation for the external signals used to drive some external high power electronic equipment when motion is detected. It's allowing up to 40V between the SSR contacts in OFF state, and currents up to 2A while in ON state, thanks to a very low ON-state resistance.Motion 4 Click board™ 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.

We provide a library for the Motion 4 Click Board™ on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Library Description
Library provides functions for controlling en pin, and getting int pin state.
Key Functions
void motion4_set_en_pin ( uint8_t state ) - Function that sets en pin stateuint8_t motion4_get_int ( void ) - Function that gets int pin state
Example Description
The application is composed of three sections :
- System Initialization - Initialization of pins
- Application Initialization - Maps pins and enables device
- Application Task - Waiting for motion to be detected
void application_task ( )
{
uint8_t int_status;
int_status = motion4_get_int();
if ( int_status != MOTION4_INTERRUPT_NOT_DETECT )
{
mikrobus_logWrite( "Motion detected", _LOG_LINE );
while ( int_status != MOTION4_INTERRUPT_NOT_DETECT )
{
int_status = motion4_get_int();
}
mikrobus_logWrite( "Motion wait", _LOG_LINE );
}
}
The full application code, and ready to use projects can be found on our LibStock page.

Additional Notes and Information
Depending on the development board you are using, you may need USB UART Click Board™, USB UART 2 Click Board™ or RS232 Click Board™ to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
MIKROSDK
The Motion 4 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.
