https://doi.org/10.1007/978-981-16-7435-8e? The term is a carryover from the old RCX days when there were only two types of sensors: those that required a power supply and those that didn’t. You probably figured out that passive sensors were the type that didn’t. The contact sensors you learned about in Chapter 4 were also passive sensors.

Lisa O’Malley,Ellen Fowler,Sarah Moore of sensors powered this way.) It’s defined as the 4.3V power supply, but the voltage actually varies about 7% with load. The plot in Figure 8-1 shows the voltage ranging from 4.6V, when the power supply is lightly loaded, to 4.0V when it’s fully loaded. It is important to note that this plot is for the total current of all the ports put together.

This capability is particularly useful for sensing objects by reflecting light off of them instead of just measuring the ambient light level. In this chapter we will show you how to add the same LED illumination control as the LEGO Light sensor.

Contact Sensors,tact sensors use the same NXT-G Touch Sensor block shown in Figure 4-1 as the LEGO ones. You probably already have everything you need to homebrew one. Even if you don’t, the parts are readily available from electronic stores such as Radio Shack, and even from hardware stores.
