The UM7 orientation sensor from Redshift Labs is an Attitude and Heading Reference System (AHRS) that contains a three-axis accelerometer, rate gyro, and magnetometer. It combines this data using an Extended Kalman Filter to produce attitude and heading estimates.

The MS5803-14BA waterproof pressure sensor module. It allows measurement from 0 to 14 bar and communicates via SPI or I2C interface. SparkFun SEN-12909

Atmospheric pressure sensor module with altitude and temperature measurement function. It has the ability to program events and sampling frequency (in the range from 1s to 9h). The MPL3115A2 sensor is fully internally compensated. SparkFun SEN-11084

The UM7-LT orientation sensor from Redshift Labs is an Attitude and Heading Reference System (AHRS) that contains a three-axis accelerometer, rate gyro, and magnetometer. It combines this data using an Extended Kalman Filter to produce attitude and heading estimates. This LT version of the UM7 does not have an enclosure.

A small module with QRE1113GR reflective sensor. The sensor is made of IR LED and phototransistor IR. With its help, it is possible to determine the brightness of the position over which it is located, it can be used, for example, to detect a black line in Linefollower robots. SparkFun ROB-09453
