SparkFun Liquid Level Sensor

Need to measure fluid levels? This eTape sensor is a solid state, continuous fluid level sensor ideal for non-nasty environments (but including water).

$39.95 USD

50826

Carbon Monoxide Sensor - MQ-7

This is a simple-to-use Carbon Monoxide (CO) sensor, suitable for sensing CO concentrations in the air. The MQ-7 can detect CO concentrations anywhere from 20 to 2000ppm.

$7.25 USD

50807

Force Sensitive Resistor - Square

These sensors are simple to set up and great for sensing pressure, but they aren't incredibly accurate. Use them to sense if it's being squeezed, but you may not want to use it as a scale.

$7.95 USD

50803

Force Sensitive Resistor (0.5")

These sensors are simple to set up and great for sensing pressure, but they aren't incredibly accurate. Use them to sense if it's being squeezed, but you may not want to use it as a scale.

Sharp Analog Distance Sensor 10-80cm

The GP2Y0A21 Sharp distance sensor is a great way to add obstacle avoidance or motion sensing to your robot or any other project. With a detection range of 4" to 32" and an analog voltage indicating the distance, this sensor is very easy to use.

$9.95 USD

17700

5mm Water-clear Phototransistor

This 5mm Water-clear Phototransistor will pick up visible and infrared light and conduct current. When light reaches this high sensitive/fast response time component it's much like current reaching the base of a transistor which allows current to flow from collector to emitter.

$0.45 USD
