How it works

MikroE Sensors MOTION click

MOTION click carries PIR500B, a pyroelectric sensor which generates a voltage when exposed to infrared radiation emitted by live bodies (the white plastic Fresnel lens covering the sensor filters visible light).

The signal is processed by a BISS0001 PIR sensor controller which sends an interrupt to the MCU through the mikroBUS INT (out) line.

An onboard potentiometer lets you adjust the detecting range of the sensor (up to 1.7 meters).

Night only mode

The click also has a night only mode—resoldering a zero-ohm jumper activates the onboard photo resistor which acts as a light-sensitive switch.

You can also switch the sensor ON and OFF by sending a signal from the MCU through the mikroBUS RST pin.

Application

MOTION click is ideal for alarm systems, light switch controllers, and similar systems where human presence needs to be detected.

Programming

Code examples for MOTION click, written for MikroElektronika hardware and compilers are available on Libstock.

This example initializes the sound port, enables the motion sensor and if activated, plays a tone.

01 void Tone1() 
02 {
03   Sound_Play(659, 250);        // Frequency = 659Hz, duration = 250ms
04 }
05 
06 void Tone2() 
07 {
08   Sound_Play(698, 250);        // Frequency = 698Hz, duration = 250ms
09 }
10 
11 void Tone3() 
12 {
13   Sound_Play(784, 250);        // Frequency = 784Hz, duration = 250ms
14 }
15 
16 void main() 
17 {
18    ANSELB = 0;                 // Configure PortB pins as digital
19    ANSELC = 0;                 // Configure PortD pins as digital
20    ANSELE = 0;                 // Configure PortE pins as digital
21    TRISB = 0x01;               // Configure RB0 as output
22    TRISC = 0;                  // Set PortC as output
23    LATB = 0x00;                // Reset PortB
24 
25    Sound_Init(&PORTC, 2);      // Initialization of sound port
26    
27    PORTE.B1 = 1;               // Enable Motion sensor
28 
29    while(1)
30    {
31       if (PORTB.B0)
32     {                        // If sensor is activated
33          Tone1();              // Play tone
34       }
35    }
36 }
