1 00:00:07,000 --> 00:00:08,000 Hello, friends. 2 00:00:08,000 --> 00:00:17,000 Today I just show you how to interface infrared sensor that is IR sensor with Matlab with the help of 3 00:00:17,000 --> 00:00:19,000 any USB 6001 DAC card. 4 00:00:20,000 --> 00:00:23,000 So for that purpose I have one IR sensor. 5 00:00:23,000 --> 00:00:27,000 As you see this is a infrared sensor module. 6 00:00:27,000 --> 00:00:30,000 And over here we have three pins. 7 00:00:31,000 --> 00:00:38,000 One is VCC, one second one is ground and third one is your output signal. 8 00:00:38,000 --> 00:00:43,000 And in this IR sensor module over here this is a potentiometer. 9 00:00:43,000 --> 00:00:47,000 Using this you can set the range of this IR module. 10 00:00:48,000 --> 00:00:53,000 This one is your transmitter and the black one is your receiver. 11 00:00:53,000 --> 00:00:54,000 Okay. 12 00:00:54,000 --> 00:01:01,000 When someone in front of this in a particular range, in a set range, it will detect the object. 13 00:01:02,000 --> 00:01:06,000 So over here I'm using port zero. 14 00:01:06,000 --> 00:01:07,000 Line zero. 15 00:01:07,000 --> 00:01:16,000 This one is purple one five volt is connected to VCC and ground is connected to the ground of that card. 16 00:01:17,000 --> 00:01:20,000 So now we go to the software part. 17 00:01:20,000 --> 00:01:21,000 First connect your. 18 00:01:23,000 --> 00:01:25,000 Descartes with your PC. 19 00:01:26,000 --> 00:01:29,000 As you see, when I just connect it, light goes high. 20 00:01:30,000 --> 00:01:31,000 Blue light turns on. 21 00:01:31,000 --> 00:01:37,000 Means your drivers are properly installed in your system for this particular Descartes. 22 00:01:38,000 --> 00:01:46,000 And when I remove my hand in front of this air sensor, only one LED goes high when I just put my hand. 23 00:01:46,000 --> 00:01:48,000 There are two LEDs in front of. 24 00:01:49,000 --> 00:01:51,000 When I just put my hand in front of this air sensor. 25 00:01:51,000 --> 00:01:53,000 There are two LEDs as you see. 26 00:01:53,000 --> 00:01:54,000 You check the. 27 00:01:54,000 --> 00:01:57,000 You can check the performance. 28 00:01:57,000 --> 00:01:58,000 This is on the hardware part. 29 00:01:58,000 --> 00:02:01,000 Now we just go to the software part. 30 00:02:01,000 --> 00:02:09,000 In the software part, you just check the device is properly connected to the system or not. 31 00:02:09,000 --> 00:02:13,000 So the command is DAC or Get devices. 32 00:02:13,000 --> 00:02:19,000 You just enter it in the command prompt as you see over here. 33 00:02:20,000 --> 00:02:23,000 National Instrument Device 6001. 34 00:02:23,000 --> 00:02:27,000 The device ID is day one connected. 35 00:02:27,000 --> 00:02:30,000 There are total analog input. 36 00:02:30,000 --> 00:02:35,000 Supports the range minus ten to plus ten volt. 37 00:02:35,000 --> 00:02:37,000 Eight channels are there. 38 00:02:37,000 --> 00:02:41,000 A0 a stands for analog input a0 to A seven. 39 00:02:41,000 --> 00:02:47,000 The rate from 0.12 to 20,000 scans per second. 40 00:02:47,000 --> 00:02:48,000 Ah, there it is. 41 00:02:48,000 --> 00:02:50,000 Voltage measurement type. 42 00:02:50,000 --> 00:02:52,000 There are two analog output supports. 43 00:02:52,000 --> 00:02:53,000 Are there. 44 00:02:53,000 --> 00:02:56,000 Minus ten to plus ten volt range. 45 00:02:56,000 --> 00:03:00,000 Reads 0.1 to 5000 scans per second. 46 00:03:00,000 --> 00:03:01,000 There are two channels only. 47 00:03:01,000 --> 00:03:03,000 A O stands for analog output. 48 00:03:03,000 --> 00:03:05,000 A zero, A01 are there. 49 00:03:05,000 --> 00:03:08,000 It is also voltage measurement type. 50 00:03:08,000 --> 00:03:11,000 Total 13 digital input output pins are there. 51 00:03:12,000 --> 00:03:17,000 I'm using in this case digital input pin. 52 00:03:17,000 --> 00:03:22,000 You can make it input only, output only or bi directional. 53 00:03:22,000 --> 00:03:26,000 Okay so I'm using port zero line one. 54 00:03:26,000 --> 00:03:29,000 In my case total three ports are there. 55 00:03:29,000 --> 00:03:30,000 Port zero, port 1 or 2. 56 00:03:30,000 --> 00:03:37,000 In this deck device, one counter is also available that is known as CDR zero. 57 00:03:38,000 --> 00:03:40,000 It is edge type counter. 58 00:03:40,000 --> 00:03:43,000 So now I just go to Simulink. 59 00:03:43,000 --> 00:03:47,000 So I already open this over here. 60 00:03:47,000 --> 00:03:49,000 This is my data acquisition toolbox. 61 00:03:49,000 --> 00:03:57,000 I already told you in my previous videos how to grab this decoration toolbox in Matlab and how to install 62 00:03:57,000 --> 00:04:00,000 the drivers of this Dec device. 63 00:04:00,000 --> 00:04:08,000 So I'm using digital input over here because I want to grab the data digitally. 64 00:04:08,000 --> 00:04:11,000 So now you just open it. 65 00:04:15,000 --> 00:04:20,000 As you see, when you first time open it, you just need to select the device devices and I. 66 00:04:20,000 --> 00:04:29,000 Day one, day one is the I'd USB 6001 and select all the pins I'm using only for zero line one pin. 67 00:04:29,000 --> 00:04:30,000 Apply it. 68 00:04:31,000 --> 00:04:34,000 Okay we need a display. 69 00:04:40,000 --> 00:04:43,000 To check the output of the sensor. 70 00:04:47,000 --> 00:04:48,000 Connect it. 71 00:04:49,000 --> 00:04:55,000 I just go with us scope also to check the output. 72 00:05:00,000 --> 00:05:02,000 Just connect it. 73 00:05:13,000 --> 00:05:16,000 So now the program is ready. 74 00:05:16,000 --> 00:05:18,000 There is a simple program. 75 00:05:19,000 --> 00:05:21,000 You just drag and drop boxes. 76 00:05:21,000 --> 00:05:22,000 Now I just open it. 77 00:05:23,000 --> 00:05:29,000 I put stop time in finite because I need for a long time. 78 00:05:29,000 --> 00:05:32,000 You can put some value also over here. 79 00:05:37,000 --> 00:05:39,000 I just open scope. 80 00:05:41,000 --> 00:05:42,000 This is the display. 81 00:05:43,000 --> 00:05:45,000 So over here. 82 00:05:48,000 --> 00:05:50,000 I just minimize it. 83 00:05:50,000 --> 00:05:56,000 So over here I get the data of scope. 84 00:05:57,000 --> 00:06:00,000 Now I just hit on run button. 85 00:06:00,000 --> 00:06:05,000 You can check the output of sensor. 86 00:06:08,000 --> 00:06:15,000 Once it is started, as you see right now it is showing one. 87 00:06:15,000 --> 00:06:18,000 When I put my hand it is showing zero. 88 00:06:18,000 --> 00:06:29,000 As you see when I change my hand very fast in front of this, it is detecting value and you just check 89 00:06:29,000 --> 00:06:40,000 the change in the scope also 010101 okay, so this is how you can acquire digital signal. 90 00:06:40,000 --> 00:06:52,000 Or you can interface either your sensor or infrared sensor to the Matlab with the help of any USB data. 91 00:06:52,000 --> 00:07:00,000 I'm just changing very fast my finger in front of this air sensor and you can check the response. 92 00:07:02,000 --> 00:07:03,000 Thank you.
