I've got an Arduino/Bluetooth (Bluetooth Bee-Standalone). I've hooked it up with an HC-SR04, it's intended to be mounted at the top of a rain barrel to measure the water depth. What's the best ...

Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

The Pressure Sensor Module incorporates a material called Velostat with the Arduino. This material adds more resistance when more pressure is applied to the material. This module also uses the RGB LED ...

Battery-powered data logger can collect up to half-million time stamped pressure and temperature data points with 8 MB internal memory, or be outfitted with 56 MB to gather 3.7 million data points.

Constructed of welded 316 stainless steel or titanium, the fully-sealed level transducer withstands the harsh agents found in a wide range of freshwater and salt water applications. These include ...
