Raspberry Pi Starter kit PCF8591 AD/DA ADS1115 High precision AD Sensor Board for Zero 2W or For 4B
$6
This product is a sensor expansion board tailored for Raspberry Pi. It is equipped with common input and output modules and sensor circuits, and LED lights flash. It can be equipped with various sensor circuits for experiments on the expansion board.
Note: Do not include Raspberry Pi, Please Buy alone.
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 |
