Brief description]
One size: 6.8CM * 2.1CM
Second, the main chip: NE555
Third, the working voltage: 12V 
Four characteristics:
1, power relay delay pull. Specifically: 12v power supply to the relay, the relay will not immediately sucked and status relay outputs are: normally open disconnected public, normally closed and public conduction; wait until the delay 1-10s (adjustable), the relay suction and, this time, the relay output status is: normally open and public conduction, normally closed and public disconnected; as long as uninterruptible power module, this state will remain.
2, the delay time is adjustable, (0 to 10 seconds)
4, increasing the potential can increase the delay time
5, increasing the capacitor C1 can increase the delay time
6, with input power indicator
7, with relay indicator
8, can control AC 220V / 10A about equipment. (Maximum control equipment 2000W)
9, with freewheeling protection relay.
10, the delay time formula: T = 1.1RC. For example: a resistor capacitor 100uf 100K T = 1.1 * 100000 * 0.0001 = 11 seconds
[Applications]
1, the delay-vehicle device is turned on, to prevent excessive current when the car ignition burn-vehicle device.
2, you need to have in order to start the occasion, to prevent multiple devices simultaneously starting current is too large burning appliances.

This is a breakout board for the very handy 16-Channel Digital Multiplexer/Demultiplexer CD74HC4067.
This chip is like a rotary switch - it internally routes the common pin
(COM in the schematic, SIG on the board)to one of 16 channel pins (CHANxx).
It works with both digital and analog signals (the voltage can't be higher than VCC),
and the connections function in either direction.
To control it, connect 4 digital outputs to the chip's address select pins (S0-S3),
and send it the binary address of the channel you want (see the datasheet for details).
This allows you to connect up to 16 sensors to your system using only 5 pins!
Since the mux/demux also works with digital signals,
you can use it to pipe TTL-level serial data to or from multiple devices.
For example, you could use it to connect the TX pins of 16 devices to one RX pin on your microcontroller.
You can then select any one of those 16 devices to listen to.
If you want two-way communications, you can add a second board to route
your microcontroller's TX line to 16 device's RX lines.
By using multiple boards, you can create similar arrangements for I2C, SPI, etc. 
The internal switches are bidirectional, support voltages between ground and VCC,
have low on resistance and low off leakage, and to prevent crosstalk, perform break-before-make switching.
The board also breaks out the chip's enable pin, which when driven high,
will completely disconnect the common pin (all switches off).
 
 
 

This voltmeter has the smallest volume in the world, and the measuring range dc dc0-100v, 2-wire and 3-wire products are universal. It breaks the conventional voltmeter. Equipped with three connections, it is convenient to access the line in the car/battery car/motorcycle. It has the function of reverse connection protection. It can be used to monitor the voltage of the battery, master the voltage state of the battery in time, and can also be used for voltage measurement of other products. Note that the maximum input voltage of line 2 should not exceed 30V, otherwise there is a risk of burnout.
Note: the three-wire voltage range is 0-100v, which can also be used as a second-line, but the voltage should be within 40V

ADS1015
 
For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1015 provides 12-bit precision at 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 12 bit converter.
The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1015's connected on a single 2-wire I2C bus for 16 single ended inputs.

Reed features:
Reed is a dry reed pipe for short, is a kind of passive electronic switching element contacts , with a simple structure , small size easy to control , etc., which is generally a sealed enclosure glass tube are installed there are two elastic spring plate of iron , also called rhodium metal filling with inert gas . Normally, the two reed glass tube made of special materials are separated . When a magnetic substance near the glass tube under the action of the magnetic field lines of the two reed tube is magnetized to attract each other in contact spring will pull together to make a circuit node connected to the communication . External magnetic disappear after two reeds are separated because of their flexibility , the line also disconnected. Therefore, as a signal to control the use of a magnetic field line switching devices , reed can be used as a sensor for counting , limit , etc. ( in the security system is mainly used for door sensor , magnetic window production ) , but also is widely used in a variety of communications devices. In practice, this is usually controlled by the permanent magnet is turned on or not two pieces of metal , it is also called " magnetron ."
Module for use:
 
1 Reed needs and with the use of magnets in magnetic induction to a certain time, will form a conduction state , the module output low, when there is no magnetic force , was disconnected state , the output high , reed and sensing distance beyond the magnet within 1.5cm of insensitivity or may no trigger phenomenon ;
 
2 module DO output can be MCU I / O port is directly connected through the microcontroller can detect dry reed pipe trigger state ;
 
3 output and relay module DO IN terminal connected to form high-power reed switches, high voltage direct control .

Product Introduction:
1.Operating Voltage: 5V
2.Pulse Number for One Circle: 20
3.Rotary encoder can count the output pulse times by rotating positively and negatively. This counting method has no limitation, it can reset and come back to the  initial status if matching with the key on the encoder (that is to say it will count from 0)
4.Operating Principle: Incremental encoder is a kind of rotary sensor which transforms the rotation displacement into a series of digital pulse signal. These pulses are used to control angular displacement. In Eltra encoder, the transformation of angular displacement adopts photoelectric scaning principle. The reading system is based on the radial dividing plate's rotation of alternative light window and non-light window, and it will be exposed to infrared light source at the same time. The light will reflect the picture of plate on the surface of receiver. The receiver is covered by a diffraction grating, and it has the same window width with the plate. The operation of receiver is to detect the change of light plate rotation, then transform the light change into electric change. Increase the low level signal into high level and generate square pulse without any interference. This process needs circuit to deal with. The reading system usually adopts differential method, that is compare two different signals who have the same waveform bu the phase difference is 180 degree so as to improve the output signal quality and stability. Reading is formed on the basis of the difference between two signals, so it eliminates the interference.
