Product Description

It is great for learning what various sensors can do, how you control them, and how you can use them together.

Turn ON/OFF LED

Some of these modules are extremely simple and basically just breakout the pins of a common device (like an LED or button) to a more larger format that is more prototyping friendly. Just simply connect a button sensor to control the led sensor on or off.

Detecting Flame

This flame sensor can be used to detect fire flame or other lights with wavelength stands at 760nm ~ 1100nm. Perhaps you can install it to monitor the kitchen or make an alarm when detecting the flame source.

Temperature and Humidity Monitor

This DHT11 Temperature and Humidity Sensor is a composite sensor which contains a calibrated digital signal output of the temperature and humidity. Use this sensor to detect the ambient temperature and humidity around you.

This kit has everything you need to start a project for all students learning about electronics and coding. Complete and popular sensor kit based on Arduino programming. It comes with detailed tutorials which include pictures and code and 37 projects, explained step by step.

37 kinds of sensors in a handheld box for you to interact with the physical world. It will provide you with endless hours of fun, entertainment, and education and will enable you to make things you didn’t even realize you needed.

This kit also has every sensor, water level sensor and electric components you will need to make hundreds of projects.

Traffic Light Senor

Upload the program to make the red, green and yellow LED on the module automatically simulate the traffic light turning on and off.

Moisture Sensor

The sensor is set with two probes which can be inserted into the soil to detect the moisture content. The higher moisture (less resistance), the higher conductivity the soil has. With the help of this sensor, the plant can remind of you: I need water.

Buzzer Beeping

In this project, you will learn how to generate a sound with an active buzzer module.

Product Description

This kit comes with more than 300pcs sensors and components, all components are carefully bagged, most of them bagged separately, with combined bags pretty logical.

The breadboard comes with a power supply, you can set one side for 5VDC, and the other for 3.3VDC. It has a push switch to turn the power on or off.

In addition, we also provide a male to male USB Power Cables, this is hard to find,but other sellers do not provide.

NOTE：This kit Not including the controller board.

The Breadboard Power Supply has two power modes:

1) M/M USB Power Cable（included in this kit）;

2) 9V 1A DC Adapter（Not included in this kit）.

Jumper Wires

Jumper wires can be used for pin extension of the experiment board, adding experimental items, and the like. It can be connected very securely to the pins, eliminating the need for soldering and allowing quick circuit testing.

Our kit includes 65pcs male to male jumper wires and 20pcs male to female dupont wires, which are completely adequate for various experiments.

74HC595

The 74HC595 consists of an 8−bit shift register and a storage register with three−state parallel outputs. It converts serial input into parallel output so that you can save IO ports of an MCU. The 74HC595 is widely used to indicate multipath LEDs and drive multi-bit segment displays. “Three-state” refers to the fact that you can set the output pins as either high, low or “high impedance.” With data latching, the instant output will not be affected during the shifting; with data output, you can cascade 74HC595s more easily.

4N35

The 4N35 is a 4-terminal universal optocoupler that blocks the electrical connection between the signal source and the receiver of the signal, which effectively blocks electrical connections and interference. Commonly used in signal isolation transmission, switching power supply feedback control and so on. Common circuits include TV power supply parts (remote control switch, voltage feedback control), switching power supply, electric vehicle charger and many other aspects.

Buzzer

An active buzzer will generate a tone using an internal oscillator, so all that is needed is a DC voltage. A passive buzzer requires an AC signal to make a sound. It is like an electromagnetic speaker, where a changing input signal produces the sound, rather than producing a tone automatically.

To identify them, if you apply a DC voltage to them and it buzzes, it’s an active.As far as commands go if you want to control the pitch, you would need a passive buzzer.

PN2222 NPN Transistor

The PN2222 can be used as a switch that use a little current from the R3 digital output to control the much bigger current of the motor. Because the small DC motor is use more power than an R3 digital output can handle directly.

1N4007 Diode

1N4007 Diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using a grey bar as shown in the picture above. For 1N4007 Diode, the maximum current carrying capacity is 1A it withstand peaks up to 30A. Hence we can use this in circuits that are designed for less than 1A. The reverse current is 5uA which is negligible.

Electrolytic Capacitor

Electrolytic capacitor is a type of capacitor that uses an electrolyte to achieve a larger capacitance than other capacitor types. An electrolyte is a liquid or gel containing a high concentration of ions. Almost all electrolytic capacitors are polarized, which means that the voltage on the positive terminal must always be greater than the voltage on the negative terminal.

Ceramic Capacitor

Ceramic capacitor uses a ceramic material as the dielectric. Ceramics were one of the first materials to be used in the production of capacitors, as it was a known insulator. Ceramic capacitors are usually made with very small capacitance values. Ceramic capacitors are also very small in size and have a low maximum rated voltage. They are not polarized, which means that they may be safely connected to an AC source. Ceramic capacitors have a great frequency response due to low parasitic effects such as resistance or inductance.
