TrigBoard Ultimate System

...Back to Projects:

• trigBoards are used in a normal way monitoring doors/windows/etc... or even modified to detect flooding, motion, force, or whatever. It does this and maintains long battery life due to its extremely low standby current. See the trigBoard page for more details. With the Ultimate system described here, this is the difference:
  • Uses ESPNow, which is an efficient point to point communication protocol. This means that when the trigBoards are triggered, they do not connect to the local WiFi network, but rather send an encrypted message to a gateway. It only takes ~1second to complete the transmission, which further improves battery life.
• No WiFi here, instead a trigBoard is configured as an ESPNow "receiver". All trigBoards used for sensors are configured to transmit to this trigBoard "gateway". This is nice because the system does not rely on a WiFi network being up running and reliably connected to the internet.
• Cellular using a Particle Boron module which does many things for the system here. This gives a nice reliable way to get the messages out without the need for WiFi. Also, these modules can be powered from USB power and/or a lithium battery. That means this is a battery backed system as well! Now, if the power goes out, the messages can still get out.
• The cellular module sends the messages out with the use of Particle's cloud and Webhook integrations. This keeps the data payloads light and things super easy to setup and modify if needed.
