The project is suppport resistive tank sensors e.g. 0-190 Ohm. The tanks could ether be of linear shape where dVolume/dResistance is constant, or nonlinear, where calibration points instead are used.

Here is a simple and inexpensive Arduino based motion sensor alarm with voice alert. It can be used for security purposes.

11 Arduino projects that require major hacking skills—or a bit of insanity Lawn care, Daleks, bug zappers prove the Arduino thrives as much as Raspberry Pi.

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

How do Arduino and Raspberry Pi compare? We break down both sides of the DIY story and provide examples of why each may be best for your particular project.
