Measure acceleration and track rotation with these accelerometers, gyroscopes, compasses/magnetometers, and combined inertial measurement units (IMUs) and orientation sensors.

This assortment of optical and sonar sensors can be used to detect the presence of objects or measure the distances to them.

These sensors use pairs of infrared LEDs and phototransistors to measure how much of the emitted IR light is being reflected from a nearby surface. They are great for edge detection and line following.

An assortment of unidirectional and bidirectional Hall effect-based current sensors. They offer a very low-resistance current path and electrical isolation between the current source and the measuring circuit. You can use these sensors to monitor your motor current, detect current spikes, or even to make inexpensive current probes for your oscilloscope.

These FSRs and FSLPs from Interlink Electronics can sense the magnitude, and in some cases the location, of an applied force, enabling unique touch interfaces and tactile sensors.

Sensors for measuring environmental properties/weather like barometric pressure, relative humidity, luminosity, and temperature.

Want to build your own breathalyzer? This variety of semiconductor gas sensors makes it possible to measure concentrations of gasses such as alcohol, methane, propane, butane, and carbon monoxide.

These quadrature encoders can be used to add speed and position feedback to an assortment of our motors with extended motor shafts.

Pololu item #: 2157
Brand: LOCOSYS
RoHS 3 compliant
Out of stock.
Quantity:

The LOCOSYS LC20031-V2 integrates a global navigation satellite system (GNSS) receiver with an embedded antenna to create a complete GNSS module that can track up to 135 signals at a time from GPS and many other satellite systems, with support for both L1 and L5 bands. It can provide updates at up to 10 Hz, has a built-in rechargeable battery for rapid satellite acquisition (external power is still required for normal operation), and outputs data as NMEA sentences through a 3.3 V or 5 V TTL-level serial port.

Pololu item #: 2138
Brand: LOCOSYS
RoHS 3 compliant
Out of stock.
Quantity:

The LOCOSYS LS20031 GPS receiver integrates a MediaTek MT3339 66-channel GPS chip with a ceramic antenna to create a complete GPS module that can track up to 66 GPS satellites at a time. The GPS module supports up to a 10Hz update rate, a built-in rechargeable battery for rapid satellite acquisition (external power is still required for normal operation), and more than 6 different NMEA ASCII sentences that are output to a 3.3 V TTL-level serial port.
