Crowtail- Mini PIR Motion Sensor
Description
The Crowtail- Mini PIR Motion Sensor is a compact, low power consumption and cost effective PIR sensor. It interfaces directly with up to two conventional PIR sensors via a high impedance different input. The PIR Signal is converted to a 15 bit digital value on chip. Is's used for making motion detecting applications such as alarm burglar systems, visitor presence monitoring, light switches and robots.

Usage
This example show you how to make a simple alarm device.
The Crowtail- Mini PIR Motion Sensor is connecting to D2 port of Crowtail - Base Shield and connect the Corwtail LED to the D5 port.
Cope the code and upload it to your arduino board.
void setup() { // put your setup code here, to run once: pinMode(2 , INPUT); pinMode(5 , OUTPUT); Serial.begin(9600); } void loop() { // put your main code here, to run repeatedly: int A = digitalRead ( 2); Serial.println(A); if(A==HIGH){ digitalWrite(5, HIGH); } else digitalWrite(5,LOW); delay(500); }
Then it Alarm "lights" will be on if it detects the body is moving.
