Home security - MQTT gateway for data gathering.
Home security project based on atmega and ardunio. MQTT gateway for data gathering.
ATMEGA - ATMEGA 1284P custom main board
Arduino environment compatiblie board with inputs outputs modified to work with sensors.
ATMEGA - ATMEGA 328P custom entry board
Arduino environment compatiblie board for remote enty.
This project should replace standard home security alarms, and And function as gateway to pass or receive data from various sensors. All configuration is done over nice web interface.
Gateway board consists of atmega1284P that has inputs for sensors and outputs to relays. It also hosts Wiz5500 Ethernet for configuration and overview, RFM69HW for radio remote nodes, communication module to wired nodes (RS485 protocol), GSM modem, Battery backed up RTC, EEPROM for log, I2C expansion connector, and AC supply and battery monitoring.
Gateway board has 8 analogue inputs that can recognize different events on PIR sensors, and 5 digital inputs. Inputs can be further expended.
Remote nodes act as authentication units or sensors. Currently they are set to receive iButtons as keys to arm/disarm the system.
