Dry reed pipe sensor module -magnetic control switch
A reed switch is a sensor that closes circuit in the presence of a magnetic field. Reed sensors can be used in many application where contact less On/Off is required. However reed switches can be fragile to use directly, hence this module can make it easier to handle and mount the sensor in various applications.
It gets operated by the applied magnetic field. When the device is exposed to a magnetic field, the two ferrous materials inside the switch pull together and the switch closes. When the magnetic field is removed, the reeds separate and the switch opens.
GAS DETECTION MODULE METHANE GAS SENSOR MQ-4
MQ-4 gas sensor sensitive material used in clean air conductivity is lower tin dioxide (SnO2). When the sensor is present in the environment in which the combustible gas, the sensor's conductivity increases with the concentration of combustible gases in air increases. Using a simple circuit can be converted to the change in conductivity of the gas concentration with the corresponding output signal. MQ-4 methane gas sensor for high sensitivity, propane, butane and has a good sensitivity. The sensor can detect a variety of flammable gases, especially natural gas, is a low-cost sensors for a variety of applications.
For home or factory methane gas, natural gas and other monitoring devices to test natural gas, methane 300 to 10000ppm;
Joystick Module Biaxial Buttons Rocker Sensor
This is a joystick very similar to the 'analog' joysticks on PlayStation 2 controllers. Directional movements are simply two potentiometers - one for each axis. Pots are ~10k each. This joystick also has a select button that is actuated when the joystick is pressed down. There are 5 pins on board: VCC, GND, X, Y and Button. Connect the module with 5V power suppy with VCC and GND, you can read out the joystick status by X,Y and button pins. When using the 5V power supply, the default analog output for X,Y is 2.5V. With the direction of the arrow, the voltage up to 5V, and the opposite direction down to 0V.
Pulse Heart Rate Sensor Module
Heart rate data can be really useful whether you're designing an exercise routine, studying your activity or anxiety levels or just want your shirt to blink with your heart beat. The problem is that heart rate can be difficult to measure. Luckily, the Pulse Sensor Amped can solve that problem!
The Pulse Sensor Amped is a plug-and-play heart-rate sensor for Arduino. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects.It essentially combines a simple optical heart rate sensor with amplification and noise cancellation circuitry making it fast and easy to get reliable pulse readings. Also, it sips power with just 4mA current draw at 5V so it's great for mobile applications.
Simply clip the Pulse Sensor to your earlobe or finger tip and plug it into your 3 *or *5 Volt Arduino and you're ready to read heart rate! The 24" cable on the Pulse Sensor is terminated with standard male headers so there's no soldering required. Of course Arduino example code is available as well as a Processing sketch for visualizing heart rate data.

EBOT Color Sensor
Ebot color sensor can detect a wide variety of colors based on their wavelength. This sensor is specially useful for color recognition projects such as color matching, color sorting, test strip reading and much more.
The color sensor uses a tcs3472 sensor chip to detect color. It also contains two white LEDs that light up the object in front of it.
EBOT LED Green
This is a bright green LED module. When you connect it to EBOT board, after program, it can emit bright Green light. you can also control it using PWM. It will be like fireflies at night. You can also combine it with other sensors to do various interesting interactive experiments.
EBOT LED Red
This is a bright Red LED module. When you connect it to EBOT board, after program, it can emit bright Red light. you can also control it using PWM. It will be like fireflies at night. You can also combine it with other sensors to do various interesting interactive experiments.
EBOT LED White
This is a bright White LED module. When you connect it to EBOT board, after program, it can emit bright White light. you can also control it using PWM. It will be like fireflies at night. You can also combine it with other sensors to do various interesting interactive experiments.
EBOT RGB LED
The WS2812B (or "NeoPixel") may look like a common 5050-sized (5x5mm) SMD LED, but there’s actually an integrated control circuit embedded inside there too. If you look really hard, you can see the tiny black chip hidden in there, along with minuscule gold wires connecting the chip to the LED. This LED is certainly more than meets the eye! The 'B' at the end of the WS2812 name denotes that these specific LEDs are equipped with and only require FOUR pins instead of SIX!
The LED itself is unlike most RGB (Red/Green/Blue) LEDs. The brightness of each color can be adjusted using a serial string to one of 256 different levels. That means there are 16,777,216 (2563) possible combinations of colors. You can produce any color from white to black (off), or salmon to sienna.
