PCF8591 Introduction

The PCF8591 is a single-supply, low-power 8-bit CMOS data acquisition device
with 4 analog inputs, one output, and a serial I2C bus interface.
Three address pins, A0, A1, and A2, are used to program hardware addresses,
allowing up to 8 devices to be connected to the I2C bus without additional hardware.

ADS1115 Introduction

The ADS1115 device is a precision, low power, 16-bit, I2C compatible analog-to-digital
converter ADC that integrates a low drift voltage reference and oscillator.
The ADS1115 performs conversions at data rates up to 860 samples per second (SPS).

20 Sensors Introduction

Model	Illustrate	The main purpose
XY rocker (JOYSTICK)	Joystick, detects the movement direction of the joystick	Robotic project joystick, analog joystick for gamepad
RELAY	Electrical control devices, electrical switches, which open and close circuits by accepting electrical signals from an external source	Various types of controllers such as TV remote control
TRACKING	Infrared detector, monitoring distance, realizes black/white monitoring of paper surface by internal infrared transmitter and receiver	Mainly used for tracking car
AVOIDANCE	Obstacle avoidance sensor to detect the distance of obstacles	Obstacle avoidance cars, robots, etc.
LINEAR HALL	Hall sensor, magnetic field detection	Door switches and robotic arm position sensors
BUZZER	Sound sensor, active buzzer is often used to issue a single prompt alarm, no frequency change, built-in oscillator	Used as a reminder or alarm device
3-color LED (RGB LED)	Create light of any color by mixing the three primary colors of red, green and blue, with different intensities to make different shades	Intensity indicator
TWO·COLOR	Dual primary color LED lights, generally red and green, are often used to indicate status	Status Indicator
REED SWITCH	Sensor for detecting magnetic field	Copiers, refrigerators, door sensors, water level meters, etc.
LASER EMIT	Using laser technology for non-contact long-distance measurement, fast speed, high precision, large range, strong resistance to light and electrical interference	Obstacle detection, pipeline counting, intelligent robots, etc.
BUTTON	Common switch modules	Digital products, remote controls, etc.
SHOCK	When the vibration is received, the on-board LED is turned on, otherwise, the on-board LED is off when it is still.	Anti-theft alarm, smart car, earthquake alarm
TILT SWITCH	Taking advantage of the good conductivity and fluidity of mercury, when the module is tilted, the mercury switch is turned on, and the onboard LED flashes; otherwise, the onboard LED light goes out	Alarm devices, communication equipment, instrumentation and other fields
PHOTOR-ESISTOR	Detects ambient light intensity and ambient brightness	Suitable for agricultural greenhouses, urban lighting and other places
TAP Module	When a tap is received, the module reacts	Suitable for alarm
BALL SWITCH	Turn the circuit on and off by tilting the module	Used as a reminder or alarm device
LIGHT BLOCKING	Open and closed circuits by blocking light	Used as a reminder or alarm device
18B20	Temperature sensor	Temperature measuring instrument
IR RECEIVER	Used to perceive certain characteristics of the surrounding environment. It does this by emitting or detecting infrared radiation	Measure heat emitted by objects and detect motion
Infrared remote control	A sensor that detects infrared radiation by using the physical effects presented by the interaction between infrared radiation and matter	Remote control
