非接触式红外触觉探测软件的编写

非接触式红外触觉传感器一般是用来检测人体热释电的，如果检测到热释电，该模块就会在控制端口输出低电平，否则为高电平。

程序如下，其在嵌入式控制器上显示热释电的情况。

底层控制板（Arduino）的范例程序如下：

#include 〈Wire.h〉

#define SLAVE_ADDRESS 0x04

int number = 0;

int state = 0;

byte sensor Pin = 16;//PC2

void setup() {

Serial.begin(9600); // start serial for output

pin Mode(sensor Pin,INPUT);

// initialize i2c as slave

Wire.begin(SLAVE_ADDRESS);

// define callbacks for i2c communication

Wire.on Receive(receive Data);

Wire.on Request(send Data);

Serial.println(＂Ready!＂);

}

void loop() {

byte state = digital Read(sensor Pin);

delay(500);

}

// callback for received data

void receive Data(int byte Count){

}

// callback for sending data

void send Data(){

int i;

Wire.write(state);

}

嵌入式控制板的范例程序如下：

import smbus

import time

# for RPI version 1, use ＂bus = smbus.SMBus(0)＂

bus = smbus.SMBus(1)

# This is the address we setup in the Arduino Program

address = 0x04

def write Number(value):

bus.write_byte(address, value)

# bus.write_byte_data(address, 0, value)

return -1

def read Number():

number = bus.read_byte(address)

# number = bus.read_byte_data(address, 1)

return number

while True:

number = read Number()

print ＂PIR:＂ number

print
