Arduino Sensor Kit 37 in 1 and 45 in 1 with Rocker Relay Microphone Temperature and Ultrasonic Modules

This comprehensive sensor kit brings together either 37 or 45 different modules designed for use with the Arduino platform, addressing the need for a convenient, all-in-one solution for electronics prototyping. Whether you are building a line-following robot, a home weather station, or an interactive art installation, having immediate access to a wide range of sensors saves time and reduces the hassle of ordering individual parts. The 45-in-1 variant expands the range with modules like an ultrasonic distance sensor, gyroscope, soil moisture probe, and a DS1302 real-time clock module, making it suitable for more advanced projects.

Complete Component Set for Prototyping

The kit is organised to cover the most common sensing modalities used in microcontroller projects. Each module comes with standard pin headers, ready to be connected to a breadboard or directly to an Arduino board. The following sections detail the key categories of modules included.

Light and Colour Sensors

Modules such as the 3-colour LED sensor, dual-colour LED, RGB module, colourful flashing LED, photoresistor, and magic light cup allow for colour detection, light intensity measurement, and visual output. These components are ideal for projects that respond to ambient light or display colour-based feedback.

Motion and Orientation Sensors

The kit includes a rotary encoder, tilt switch, vibration switch, and a hunting sensor module (likely a PIR motion detector) to detect movement or changes in orientation. The addition of a gyroscope in the 45-in-1 set enables orientation tracking for balancing robots or motion-controlled interfaces.

Environmental and Safety Sensors

Temperature measurement is covered by digital temperature, analog temperature, 18B20, and temperature/humidity sensors. A flame sensor detects fire or strong infrared sources, while a water level sensor (45-in-1 only) monitors liquid levels. The soil moisture module is useful for automated watering systems.

Audio and Signalling Modules

Sound input and output are addressed through several modules, enabling audio detection and audible feedback in your projects.

Microphone and Sound Detection

Two types of microphone modules are provided: a high-sensitivity microphone and a small microphone sensor (also listed as microphone sound sensor). These can be used for voice control, clap-activated switches, or sound level monitoring.

Buzzer and Alarm Output

Both active and passive buzzer modules are included. The active buzzer emits a fixed tone when powered, while the passive buzzer can be used to play variable tones by supplying a square wave from the Arduino. They are suitable for alarms, notifications, or musical tunes.

Control and Interface Modules

A selection of modules allows interaction and control for more complex projects.

Input Devices

The kit contains a rocker sensor (likely a joystick module), key switches, a rotary encoder, and a PS2 joystick module (45-in-1 only). These provide manual control inputs for robotics, menus, or gaming applications.

Output and Actuation

A 5V relay module enables switching of higher-power devices such as lights or motors. Laser head sensors provide a focused light beam for detection or communication. The MP1584EN buck module (45-in-1) allows voltage regulation for powering the Arduino or other components from a higher voltage supply.

Specialised Modules for Advanced Projects

Some modules cater to more niche applications, expanding the kit's versatility for experienced makers.

Magnetic and Metal Detection

Hall effect sensors (linear, analog, and magnetic force), a mini and large magnetic reed module, and a metal touch sensor allow detection of magnetic fields and metallic objects. These are useful for security systems, motor speed measurement, or proximity sensing.

Communication and Memory

The SD card read/write module (45-in-1) provides data logging capability, while the infrared emission and receiving sensor pair enables wireless communication. The DS1302 clock module adds real-time tracking for time-stamping data or controlling time-based events.

Benefits and Buying Value

This sensor kit offers substantial time and cost savings compared to sourcing each module individually. With a broad range of sensors covering light, sound, temperature, motion, magnetic fields, and environmental variables, you can quickly prototype a wide variety of Arduino projects. The 45-in-1 version adds even more versatility with modules for distance measurement, motion tracking, soil and water monitoring, and data storage.

Reuse and Low Maintenance

Each module is durable and easy to reuse across multiple projects. Simply disconnect and store the modules for future builds. No special maintenance is required beyond keeping them in a dry, static-free environment.

Why Choose This Product

If you are starting with Arduino or looking to expand your sensor library, this kit provides a cost-effective, all-in-one solution. The inclusion of both common and specialised modules at a single price point makes it especially attractive for educational settings, hobbyists, and anyone who wants to experiment with diverse sensor technologies without repeated purchases.
