<p>This device uses infrared technology to sense distance between itself and the nearest surface between 8 and 60 inches. Our version of this sensor includes a conditioner to fully buffer and scale the signal to the industry standard voltage range of 0.25-4.75 Volts, perfect for the Teabox.</p> <p>As with all of our sensors, we have taken care to make certain that this sensor is of high quality. For the hacker or do-it-yourselfer we also offer a &#8220;project version&#8221; of this sensor (see the specification sheet for more details), which comes at a reduced price.</p> <p><strong>IMPORTANT <span class="caps">NOTE</span>:</strong> This sensor draws a lot more power than most sensors. This results in the Teabox being limited to handling 3 of these sensors at a given time. There are solutions to work around this.
