Sensor Meter
Building  
Programming  

This handheld device uses several different sensors to measure and graph values on the display. You can use it to experiment with how the various sensors behave.

A sophisticated program is included that has 9 different modes to measure various sensor values over time. Several of the modes display a scrolling bar graph that shows the relative value of the last reading as well as the last 4 values before that. You can even adjust the sampling rate (number of samples taken and plotted per second) using the twist knob on the motor. See the programming instructions for details on the various modes.
