The HC-SR is a motion sensor module that is inexpensive and very versatile. It can be used all by itself or combined with a micrrocontroller or microcomputer to create a number of motion sensing products. Introduction There is no denying it — human beings are hot stuff! Humans and animals radiate body heat to such a degree that the temperature of a room rises when people enter it. That rise in heat level experienced when a person enters a room can be detected and used as a trigger for a number of devices.
Burglar alarms and intruder detectors are obvious applications. Another common reason to detect the presence of people is for energy-saving lighting systems that only come on when a room is occupied. Of course there are a number of ways to detect people. We have already seen the HC-SR04 Ultrasonic Sensor , this device can be used to detect an intruder by reflecting an ultrasonic signal back to a sensor. Unlike other sensors which emit and then detect infrared light a PIR sensor does not emit anything.
Rather it measures infrared energy in a room and is triggered upon a sudden change in it, such as the change that occurs when a warm blooded mammal enters the room. We discussed infrared light when we worked with IR Remote Controls. A measurement of IR energy is not the same as measuring temperature. It then looks for abrupt changes to this IR signature, changes that occur because a living being has entered or moved within the monitored area.

解决Multiple Sensors on Raspberry Pi GPIO
The remaining pins consist of power supply 5v and 3. In future, this might change. This is a really simple library which allows you to read to and write from any GPIO pin by various means like polling, triggers, events, etc. GPIO library comes pre-installed with the latest version of Raspbian.
Hook up the Arduino to the Raspberry Pi via USB Step 9. On the Raspberry Pi, make a python program that uses the serial module to read data coming out of the Arduino.
So instead, our network scanner is going to be plenty visible. Follow along with our live build while you make your own: Buying Hardware Most of the hardware for this project is fairly easy to get a hold of and, apart from the giant seven-segment displays and the controller boards for them, you may well have most or even all of the bits and pieces you need kicking around your workshop already.
It can also be put together with minimal soldering. The only soldering needed for the project is attaching the controller boards to the seven-segment displays. There are really only two or three chipsets used inside mass market USB wireless adaptors. Having another USB wireless dongle in your spares box is always handy. Some of these chipsets are harder to get working in monitor mode than others.

Editor’s note, 28 July
Feb 14, · Hey Guys. I’m trying to hook up an analog sensor to the raspberry and since that won’t work I was thinking about using the Arduino to do it for the raspberry.
It is possible to wire up more than one display! However I suspect the rest of the wiring might be somewhat challenging… Wiring is described at the end of the this page. The LCD library will call pinMode functions, but these are ignored if you have already set the modes using the gpio program and want to use the wiringPiSetupSys mechanism. Rows and cols are the rows and columns on the display e.
Bits is the number of bits wide on the interface 4 or 8. The rs and strb represent the pin numbers of the displays RS pin and Strobe E pin. The parameters d0 through d7 are the pin numbers of the 8 data pins connected from the Pi to the display. Only the first 4 are used if you are running the display in 4-bit mode. Usually incorrect parameters In the above Fritzing diagrams, the 4-bit one would be initialised by: At the moment, there is no input cursor control and no clever scrolling or wrapping of data sent to the display.
It is up to your program to manage the display as it needs to.
Using the HC-SR501 PIR Motion Sensor – With Arduino & Raspberry Pi
Have all the parts on-hand, check out the Google spread sheet. Have a working and installed OS on the Pi. Adafruit Occidentalis or Raspbian work well. Have the Wifi Adaptor setup and ready to go:
Connecting an Arduino to a Raspberry PI using I2C. petermount1 February 15, May 28, Arduino, Raspberry PI, Power up both the Arduino and Raspberry PI. Once it’s up and running log in and run i2cdetect: but I was wondering whether it would also work it I were to hook it through I2C (to liberate the USB port). Any thought.
These are only necessary for the initial setup until you have the Pi networked after which you can go headless and SSH in from another computer. The one you want for this project is Raspbian. Complete the Raspbian setup and you should have a working Pi at the end. It’s at this step that I encountered my first problem. The problem turned out to be the USB ports on the Pi doesn’t provide enough power for the keyboard and mouse.
You can get around this issue by using a powered USB hub. Step 4 – Setting up Wifi You can skip this step if you’re going to leave the Pi connected with ethernet cable. In fact, I recommend skipping this step until the end to simplify things. I didn’t want the Pi to be tethered by an ethernet cable so I proceeded to try and set it up with the USB wifi dongle.
This turned out to be probably the hardest part of the project.
Flashing ESP8266 with NodeMCU (Windows, Linux, Arduino and Raspberry Pi)
This micro-controller contains a Tensilica chip core as well as a full WiFi stack. Now we will start our project: Hardware Components and important links:
The world of Raspberry Pi is evolving quickly, with many new interface boards and software libraries becoming available all the time. In this video, prolific hacker and author Simon Monk introduces more than 60 practical recipes for running this tiny low-cost computer with Linux, programming it with Python, and hooking up sensors, motors, and other hardware—including Arduino.
Sometimes they move to being a product, sometimes not. We have been on the lookout for a good pluggable prototyping system that allows swap outs of parts and yet has a good mechanical interface. We have looked at a variety of systems over the years. What did we want? We wanted something that is supported by a number of manufacturers, no licensing fees involved, easy for beginners and younger folks to use, straight forward enough so we can build boards without much problem and flexible enough for use with all three of the Raspberry Pi, Arduino and the ESP We have now found such a system that has some significant support in the industry.
All of the parts in this tutorial are available from www. What is the Grove System? Grove is a modular, standardized connecter prototyping system. Grove takes a building block approach to assembling electronics. Compared to the jumper or solder based system, it is easier to connect, experiment and build and simplifies the learning system, but not to the point where it becomes dumbed down. Some of the other prototype systems out there takes the level down to building blocks.
Good stuff to be learned that way, but the Grove system allows you to build real systems. It requires some learning and expertise to hook things up.
USB to TTL Serial Cable – Debug / Console Cable for Raspberry Pi
There is no need for a cross over cable, as the RPi can handle it. I have a blog post that documents this with pictures here which may be easier to follow. Unzip the zip file and open the dhcpwiz application, which will configure the DHCP server. Connect the Ethernet cable from the RPi to your laptop, and turn on the Pi. Hit refresh on this screen until the IP address changes to
MyDevices Cayenne is a drag-and-drop project builder for designing IoT systems. It is by far the easiest way to start creating IoT solutions with the Raspberry Pi and now also supports the Arduino.
Read on below to get started! These brilliant LEDs come in all sorts of shapes, ranging from strips, circular rings to matrices. What makes these LEDs especially great, however, is that they are really, really bright! Unlike ordinary LEDs which have a diffusing cylindrical like cap on the top, these simply have a flat transparent plastic covering. The only slight caveat to these LEDs, is that they can only be driven by a dedicated microcontroller like an Arduino board.
This meant a Raspberry Pi was out of the question. This will allow us to use the LED ring as a circular gauge for the temperature readings. And for those feeling extra ambitious, an extra section will show you how to transmit the readings over the Internet to a real time plotting service Plot. So what do we need? As you probably know, there are many ways to set up a temperature sensor with a Raspberry Pi.
