When the sensor detects that the moisture content is already below 30%, it sends a signal to the Arduino, which, in turn, activates a water pump to provide hydration to the plant.

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.

The Saturn’s electronics aren’t sophisticated enough to implement a lean burn system simply, and so [Robot Cantina] did what any of us might have done: hacked it in with an Arduino.

This means you won't have to go out of your way to buy a separate board. The Uno Rev3 is also the most popular Arduino board, so expect to see tutorials and project guides available online.

Inspired by a Arduino based LIDAR system, [Berryjam] decided that he wanted to successfully use an affordable Open Source Laser RangeFinder (OSLRF-01) from LightWare.

With over 20 unique sensor types, and the ability to be used with several different development platforms, Tarts wireless sensors allow for endless sensing, monitoring and control possibilities.
