This book discusses the basic components of any alarm system. All alarm systems have two basic functions. First, they monitor their environment looking for a change such as a door or window opening or someone moving about in the room. Second, they alert the legal owner or user to this change. The system described in this book uses a scanning type software to detect intruders. It behaves like a guard dog, pacing up and down the fence line on the lookout for either an intruder or a familiar person. If you have an alarm key, you can disarm the system and enter. With the scanning method, the software is easy to write and explain. It can scan eight alarm zones plus two special fire zones in about one second. You don’t have to be an electrical engineer to install an alarm system, just a decent carpenter, painter, and plasterer! Because this alarm system runs on 12 volts, you don’t have to be a licensed electrician either to install it. The alarm system presented here uses Python software on the Raspberry Pi combined with some elementary electronic circuits. The code described in the book, as well as CAD files and a bill of materials for the alarm panel, are available for free downloading. The book provides the reader with examples of typical configurations coming straight from the author‘s experience. After reviewing the hardware components typically used in common alarm systems, the author shows how to plan one yourself. To implement a modular alarm, no matter if it is for a single house or for a business or restaurant, the book shows how to skillfully combine a Raspberry Pi with small auxiliary electronic circuits. These are not installation instructions but food for thought that will enable readers to find a solution to their needs.

Features Stereo input and output Dedicated 192 kHz / 24-bit high-quality Burr-Brown DAC Dedicated 192 kHz / 24-bit high-quality Burr-Brown ADC Hardware volume control for DAC. The output volume can be controlled using “alsamixer” or any application that supports ALSA mixer controls. Connects directly onto the Raspberry Pi. No soldering required. Compatible with all Raspberry Pi models, that have a 40-pin GPIO connector No additional power supply required. Three ultra-low-noise linear voltage regulators. HAT compliant, EEPROM for automatic configuration. Gold plated RCA output connectors. Includes 4 M 2.5 x 12 mm spacers. Balanced/unbalanced input connector (P6) The 5-pin connector can be used to connect a balanced input. Please note that the balanced input has to be selected with the jumpers and will always have a 12 dB gain. It shouldn't be used with line-level inputs. Pin 1 is on the left. right + right – GND left – left + Output connector (P5) The output connector realizes connections to external components like an amplifier. Pin 1 is on the top left. +5 V 1 2 R GND 3 4 GND +5 V 5 6 L Input gain settings (J1) The jumper block is responsible for the input configuration. It is recommended to use the default setting without additional input gain. 32 dB gain can be used to connect dynamic microphones.

Click here to learn how to update the Raspberry Pi kernel Using microphones with the DAC+ ADC The DAC+ ADC is equipped with a stereo analogue input that can be configured for a wide range of input voltages. It performs best with line-level analogue sources. However, it is also possible to use it as a microphone input. You can only use dynamic microphones. Microphones that require a power supply are not supported. The microphone output voltage is very low. This means you need to amplify it. The DAC+ ADC has the necessary pre-amplifier already equipped. You will have to set the jumpers correctly. The sound from the input won’t be played back automatically on the output. You will have to use some software that reads the input and outputs it again. Setting the correct input amplifier settings for a microphone By default, the input sensitivity is matched for line-level audio sources. This is done via a jumper on the J1 header. Audio input to output There is no direct connection between the input and the output. That leads to the input from the connected microphone to not be played back automatically. If you want to hear it on the output, you need to use the command line tool alsaloop can be used for this.
