"37 Sensors" is the common name for a number of kits of small electronic modules. Although a large number of these modules are what would be considered "sensors", some are certainly not sensors (things like RGB LEDs and relays).
See this 37 Sensors Site for more information.
Also called: linear hall, magnetic hall, KY035, KY024.
Returns an analog signal based on the intensity of a magnetic field. Module outputs the analog sensor signal, as well as (for some modules) a digital signal that is switched high when the sensor level crosses a preset threshold. The threshold is set via the potentiometer.
Also called: joystick, mini dual axis joystick, KY023.
A joystick made from two typically 10k potentiometers at right angles to each other. Analog output in both x and y directions. Push knob down for momentary switch.
Also called: temperature sensor, thermistor, KY013.
A thermistor used for temperature sensing. Analog output.

Also called: momentary button, key switch, KY004.
Simple pushbutton switch.
Also called: fire detector, KY026.
A detector that outputs a digital state based on the presence of a flame or fire. Can be used for fire detection. Module outputs the analog sensor signal, as well as a digital signal that is switched high when the sensor level crosses a preset threshold. The threshold is set via the potentiometer.
Also called: magnetic field sensor, KY003.
Detects the presence of a magnetic field. Digital on/off output. Can differentiate between north and south magnetic poles with front or back of the sensor.
Also called: humidity sensor, DHT11, KY015.
DHT11 digital (protocol) device that measures humidity and temperature.

Infrared sensor. Will demodulate the signal from a 38kHz carrier.
Also called: IR emission, infrared transmitter, KY005.
Also called: laser emit, laser transmitter, laser diode, KY008.
Also called: magic cup, KY027.
A mercury switch paired with an LED.
Also called: tilt switch, quicksilver switch, KY017.
A small glass vial with two contacts and a bit of mercury inside. Acts as a tilt switch.
Also called: sound sensor, big sound, small sound, microphone big, microphone small, microphone sensor, KY037, KY038.
A module that uses a high sensitivity electret microphone to detect sound. Module outputs the analog sound signal, as well as a digital signal that is switched high when the sound level crosses a preset threshold. The threshold is set via the potentiometer.
Also called: 7 color flash, autoflash LED, polychrome flash, KY034.
An LED that flashes through a sequence of seven multiple colors.
Also called: infrared avoiding, wall sensor, reflective sensor, KY032.
A phototransistor and infrared LED pair for the detection of an obstacle. Can be used for robotics. The detection distance is about 1/4 of an inch. An enable input to the module enables or disables the circuitry.
Also called: slot sensor, notch sensor, light block sensor, KY010.
An LED and a phototransistor that detects an object in the slot between the LED and detector.
Also called: light detector, optosensor, KY018.
A resistor that changes resistance based on light level.
Also called: active buzzer, KY006.
Piezo or small speaker that generates a fixed tone. This is a piezo element along with a fixed frequency driver circuit.
Also called: heartbeat sensor, KY039.
An infrared LED and photodetector/phototransistor pair used to detect pulse/heartbeat through a fingertip.
Also called: magnetic spring switch, mini reed switch, KY025.
A switch that closes in the presence of a magnetic field. Module outputs the analog sensor signal, as well as (for some modules) a digital signal that is switched high when the sensor level crosses a preset threshold. The threshold is set via the potentiometer.
Also called: full color LED, three color LED, trichromatic LED, KY021, KY016.
LED containing red, green, and blue emitters, each controlled independently. Some modules have current limiting resistors, some do not.
Also called: Incremental encoder, KY040.

Also called: tap sensor, knock sensor, shake sensor, percussion sensor, spring switch, vibration sensor, impact sensor, KY002, KY031.
The sensor is designed to act as a switch. Detects tapping/knocking or vibration.
Also called: relay, one-channel relay, KY019.
A driver circuit and single 5V relay that can control greater voltages/currents. Can make a direct connection to the microprocessor as this board has a relay driver circuit to drive the relay coil. Contacts typically rated for 10 amps.
Also called: passive buzzer, non-sctive buzzer, piezo speaker, KY012.
Speaker or piezo for sound output.

Also called: metal touch sensor, KY036.
Touching a contact on this module is detected and results in a changed output. Module outputs the analog sensor signal, as well as a digital signal that is switched high when the sensor level crosses a preset threshold. The threshold is set via the potentiometer.
Also called: infrared tracking, optical tracking, tracking sensor, line follower, hunt sensor, KY033.
A tracking or “line following” infrared LED and phototransistor module. The sensor is an IR emitter adjacent to an IR receiver. Reflection of the IR signal (an object in front of the sensor) will cause the digital out signal to go low. Detection distance is typically about a half inch. Sensitivity can be adjusted with the potentiometer.
