2 Section 18650 Lithium-Ion Battery Support Bracket made of flame retardant ABS+PC materials, with high-temperature resistance and crack resistance. There are slots on the edge of the holder that can be combined to create a battery pack of many different sizes and shapes; after welding nickel tabs, the pack can pass vibration testing without using any other connecting device that makes your battery pack Solid and Reliable.
18650 (18mm diameter and 65mm Length) is one of the most common cell sizes found worldwide. So it can be easily replaced in any battery-powered application. We need many cells to build a battery pack to power the high power devices like your laptop, small RC cars, or even any small Digital circuit with many sensors and actuators.
These Double Cell brackets will allow you to quickly build your battery pack without the assistance of any professional. Simply stack them with their hooks in any number you want, and you have a 18650 battery holder. The connections can then be made with metal tapes/strips. Because each bracket can hold two cells, you'll need two brackets for every two cells, one for the top and one for the bottom.

1 Channel 5V Relay module is used as a switching device and as it is a single channel this module can control only a single circuit. Relay modules with multiple channels can control multiple circuits.
This module consists of 6 input-output pins i.e., Vcc, GND, IN, Common (COM), Normally Closed (NC) and Normally Open (NO). Vcc and GND are the two ends of the coil inside the relay. These pins are used to trigger ON/OFF the relay. Vcc is connected to 5V DC and GND is connected to the ground. At Input pin, we give a signal from a microcontroller to allow/disallow current to flow through the coil. Common is connected to one end of the device to be controlled. The other end of the load is either connected to the NC or NO. If the load is connected to NC then the device remains connected before trigger and if it is connected to NO then the device remains disconnected before trigger. The trigger voltage of this module is 5 V.
Devices operating on 10A, 250V AC and 10A 30V DC can be used as load devices for this module. When the trigger voltage is supplied the coil is turned ON and then the contact between common to NC is changed to common to NO. and when trigger voltage is not supplied to the relay the contact comes back to common to NC from common to NO.

This is 0.28-inch Digital Voltmeter Ammeter DC 100V 50A LED Amp Volt Meter With Shunt. This meter will measure up to 100 VDC with a 0.1-volt resolution.
One thing to note is, this meter has 2 wiring harnesses. One harness is to provide power for the meters, that’s the 2 poles with a RED and a BLACK lead. Small size, portable, the magnitudes of voltage and current are displayed on the same screen at the same time.
This can be supplied anywhere from 6 volts DC up to 30 VDC. This is a separate power supply that is isolated from the source, it is possible to use the same supply but it seems to affect the amp meter reading. The 3 wire harness is used for a ground that connects directly to the battery or supply ground of the load.

This is All new tiny and compact digital voltmeter with a RED LED Display. The 0.56inch 0-100V Three Wire DC Voltmeter Red Panel requires only a few minutes of configuration and is as simple as directly connecting wires to the source you want to measure and seeing the LED blink!!!!
The red wire is to connect to the positive pole, the black wire is to connect to negative pole and the yellow/white wire is to connect to the positive pole of that source or another source across which we meant to measure the voltage. While measuring the supply voltage of another source make sure that the negative pole is joined common. No need to worry even if there is any connection mismatch of the wires, the electric circuit won’t be a boom because it features reverse polarity protection.
To reach the best measurement accuracy, this voltmeter will automatically move the decimal point’s position according to the different measuring voltage. When it measures the voltage below 10V, it will display two places after the decimal point. When it measures the voltage above 10V, it will display one place after the decimal point.
This voltmeter can be used to measure the storage battery’s voltage upto 100Volts in motorcycles and cars and also can grasp the storage battery’s status. It also can be used to measure other DC voltage. This voltmeter can operate on versatile 4.5V to 30VDC range is the voltmeter’s maximum operating limited voltage, please leave enough margin (i.e. do not reach up to last limit which is 30V ) when working, to avoid voltmeter’s permanent damage because of an electrical spark, power supply ripple, or other too high abrupt change of voltage.
Very bight and decent LED Display is ready to measure the dc voltages in the range of 0V to 100V.

2N2907A is a semiconductor device used to amplify or switch electronic signals and electrical power. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits.

SPDT(Single Pole Double Throw) relay is used as a switch for high current AC/DC appliances which need to be controlled from a microcontroller or sensor output. 24V PCB Mount Sugar Cube SPDT Relay instead of its small size can switch a load of 7A connected to it. The coil resistance of this relay is 1.6k ohm whereas the coil current is 15 mA. The trigger voltage for this relay is 24V.
There are 5 pins in this relay i.e, Coil end 1, Coil end 2, COM(common), NC and NO. Coil end 1 and Coil end 2 are used to trigger ON/OFF the relay. One end is connected to a 24V supply and the other is connected to the ground of the circuit. Common is connected to the one end of the load to be controlled. The other end of the load is connected to either NC or NO. If the load is connected to NC(Normally Closed) then the load remains ON before trigger. And if it is connected to NO(Normally Open) then the load remains OFF before trigger. These relays are usually used in home automation, switching circuits, security circuits, etc.

This YF-S201 1/2 inch Water flow sensor consists of a black plastic valve body, a water rotor and a hall effect sensor. 1-30 Litre/min Water can flow through this sensor. This YF-S201 is placed in line with water and its pinwheel sensor detects how much liquid has flowed through it. With every pinwheel revolution magnetic hall effect sensor generate an electrical pulse which is fed to the controller and thus controller is able to detect how much liquid is flowing through the sensor at any point of time. The hall effect sensor is sealed from the liquid pipe and thus remains protected from the water.
The Electrical pulse generated by the sensor is approximately equal to 2.25 milliliters. So by counting the number of pulse we can easily calculate the amount of water flowing through the sensor.

A float switch is a device used to sense the level of liquid within a tank, it may actuate a pump, an indicator, an alarm, or other device.
A float switch is a device used to sense the level of liquid within a tank. The switch may actuate a pump, an indicator, an alarm, or other device. Use them with hydroponics, saltwater tank, freshwater tank, gardening, aquariums for power head control, pet bowls, fish tanks, filtration, heating, pumps, ponds, basement alarms, boats, air condition drain pans, pressure washers, carpet cleaning mach, reef aquarium, fluid control, ice machines, coffee pots, marine, automotive, automobiles, tropical fish tanks, evaporator coils, condensation line, in relays, or whatever your project may be. It can be easily converted from normally open to normally close by inverting the float.
