Story

Most dog owners would agree that their furry friends are important members of the family who deserve all the love and care in the world. The last thing anyone would want is for their dog to be stuck outside on a hot day with no water.

With the Smart Dog Bowl, three sensors work together to notify pet owners when water levels are dangerously low. So you never again have to worry about your furry friend not having water.

Argon number one has the water level sensor with jumper wires connecting the negative sensor terminal to ground on the argon, the positive sensor terminal to 3V3 on the argon and the S sensor terminal to A0 on the argon.

Argon One (Water Level)

Argon number two contains an LCD screen that displays LOW, MEDIUM, and HIGH levels as detected by argon one. The variable resistor aids in adjusting the brightness of the LCD screen.

Argon Two (LCD)

Argon number three has a green led light that is on when the water bowl is adequately charged. No green light means the bowl's batteries should be replaced.

Argon Three (LED)
