Remote Boat Monitor - (via WI-FI). |
|
|
It is always nice to know that your baby is safe and still floating where you left her. This remote electronics ins intended to monitor bilge pump activity, system power, cabin temperature and humidity. The monitor will connect to the Internet via WI-FI. Notifications will be emailed instantly from the Monitor to my email address at home or to my cell phone, regardless of where I am in the world. Peace of mind. In addition, if there are no events to transmit, the RaspberryPi will transmit a "keep alive or heartbeat" email to indicate it is still alive and functioning. Our club video camera of the moored fleet only goes so far to monitor boats and this Monitor will report the other vital statistics I want. DESIGN - The circuitry is being configured and tested on a bread board. The RaspberryPi is programmed to wake up whenever an event happens, send the information in an email then go back to sleep.
LOCATION - All electronics demands a dry location to prevent corrosion. For this reason the circuitry will be housed in a plastic project box installed above Panache's starboard settee. This location is beside the secondary power distribution panel from where it is a short distance to connect to the terminal strips for sensory input signals. CONSTRUCTION - The final circuit will be constructed on Veroboard for simplicity with terminal strips for robust external connections. POWER - Permanent 12VDC equipped with transient suppression to prevent false triggers. The sleep current draw is a measly 2 MA. VISIBILITY - Still unsure if we want a local indication, audible or visual, of a trouble. _______________________________________________________
