RAM Electronics's Description
The H2OhNo! is a water sensor alarm kit that you build yourself. When water
is detected across the sense pins an alarm goes off and an LED starts blinking.
If you’ve ever had a water heater explode or tried to create submersible
electronics you know how important it is to be able to detect when water is
Underneath the default function of H2OhNo! is a small but powerful
development board for the ATtiny85 microcontroller. The board includes a
buzzer, LED, a coin cell battery, and the ability to detect analog and digital
sensors. This mixture of parts creates a great low-cost tool to learn how to
program and sense things!
This board can be re-programmed to be an Annoy-A-Tron (originally made by
Think Geek). Please annoy respectfully, otherwise your board may get demolished.
