4. Sensing movement, sound and light.

The sensor breakout boards we are going to use in this module are the following:

Image result for temt6000

This sensor senses light more accurately than the LDR photocell we used before, using a phototransistor. It has one analog out pin.

Passive infrared (PIR) sensor HC-SR501

This is an infrared motion detector, that gives a digital output.

Waveshare sound sensor

This is an audio breakout that can be used as an audio amplifier, an ambient sound detector or as a sound level detector. It has one digital output and one analog.
