A light sensor or light trigger detects and measures ambient light and the change of ambient light. In the simplest way, it can be used to determine whether i.e. it is day or night.
There are different sensors. Most commonly used are Photoresistors, Photodiodes and Phototransistors.
Specifications
Type: Photoresistor
(light dependent Resistor, LDR)
Category: Sensor, Input
Operation: Analog, (infinitely adjustable)
Voltage: 3.3V (max. 5V)
Reading: 0 – 1023
Pinout: (-) Ground, (+) 3.3V, (S) Signal
Muse Color-Code: Red
Functional principle
The Photoresistor is a light-sensitive semiconductor whose resistance will decrease with increasing amount of ambient light.
(more light = less resistance = greater output voltage).
It can infinitely vary the output voltage from +0V to +5V, dependent on the light source.

Sound Sensor
Description
A sound sensor or sound trigger detects and measures ambient sounds and the change of ambient sounds. It is often used with clapping hands to trigger an action.
The Sensor consists of a microphone and an amplifier.
Specifications
Type: Loudness Sensor
Category: Sensor, Input
Operation: Analog, (infinitely adjustable)
Voltage: 3.3V (max. 5V)
Reading: 512 ± 212 (300 – 800)
Pinout: (-) Ground, (+) 3.3V, (S) Signal
Muse Color-Code: Red
Functional principle
The microphone of the loudness (sound) sensor reacts to ambient sounds or more precisely to soundwaves. Similar to the human ear, the microphone contains a membrane that will oscillate to the soundwaves. Close to the membrane is another plate, together they form a capacitor that can store electrical energy. The stronger the membrane swings, the greater the capacity. (louder noise = stronger oscillation = more capacity = greater output voltage). It can only measure the loudness (the amplitude or how strong the membrane swings), not the pitch (frequency or how often the membrane swings).
The sensor provides a “silent” analog reading of 512 due to the basic minimal capacity of stored electrical energy.

Motion Trigger
Description
The PIR (passive infrared) sensor reacts to changes in heat radiation in the infrared spectrum and therewith detects motions of objects, humans and animals, it does not react to changes of sunbeams.
Specifications
Type: passive infrared sensor
Category: Sensor, Input
Operation: Digital
Voltage: 3.3V (max. 5V)
Reading: 0 or 1
Coverage: 120°
Pinout: (-) Ground, (+) 3.3V, (S) Signal
Muse Color-Code: Red
Functional principle
The PIR doesn’t measure heat like a thermometer but instead measures the heat of lightwaves. It is a passive sensor and does not send waves itself, unlike active infrared sensors.
If an object is detected as moving, the sensor will send a HIGH signal (1), else will remain a LOW (0).

The heart of the sensor is the TMP36, a low voltage, precision centigrade temperature sensor. It is calibrated directly to Celsius and does not require any external calibration. It has a low self-heating tendency and is therfore ideal for most projects and applications.
Specifications
Category: Sensor, Input
Operation: Analog
Voltage: 3.3V ( min. 2.7V – max. 5.5V)
Reading: 10 mV/°C (−40°C to +125°C)
Accuracy: ±2°C
Pinout: (-) Ground, (+) 3.3V, (S) Signal

Dimmer
Description
The Dimmer is a resistor with sliding or rotating contacts that form an adjustable voltage divider. It is commonly used to control electrical devices, such as the volume on audio equipment. It is done by varying the current flowing through the resistor.
Specifications
Type: Potentiometer
Category: Sensor, Input
Operation: Analog (max. 1 Watt)
Reading: 0 – 1023
Pinout: (-) Ground, (+) 3.3V, (S) Signal
Muse Color-Code: Red
Functional principle
The rotational sliding contact (wiper) moves along a resistive element from one end to the other, thus increasing or decreasing the resistance. (less resistance = greater output voltage).

Push Button
Description
The pushbutton is a momentary switch which handles two states, pressed or not pressed, and is often used to initiate an action on a button press or performs an action as long as the button is pressed or released respectively, i.e. LED illuminates while the button is pressed.
Specifications
Type: Switch
Category: Sensor, Input
Operation: Analog, Digital
Reading: 0 or 1023, 0 or 1
Default: HIGH on released state
Pinout: (-) Ground, (+) 3.3V, (S) Signal
Muse Color-Code: Red
Functional principle
The pushbutton contains a simple mechanical switch mechanism that will either opens or closes a circuit, depending on the state of the button, and lets current flow or not. It can be read in analog, returning a low value of 0 when pressed and a high value of 1023 when released, or digital, returning 0 when pressed and 1 when released.

Raindrop Sensor
Description
The raindrop sensor will detect waterdrops that fall onto the surface of the sensor board, shorting two else separated circuits. The two circuits are commonly nickel coated lines that run in a specific pattern to cover the surface area allowing the two circuits to be close to each other without establishing any connection. The gap between the nickel lines are small enough that they can be bridged by the size of a single raindrop, thus closing the circuit and detecting the raindrop.
