DC 5V Waterproof Ultrasonic Module Distance Measuring Transducer Sensor (waterproof ultrasonic)
This waterproof ultrasonic distance sensor is for those applications that are a bit more rugged! 25cm - 200cm sensing range.
We have used the HC-SR04 Ultrasonic Distance Sensor many times and for many good reasons. It is pretty easy to use, it performs well, and it is very inexpensive. For collision avoidance robots or intruder detection, this sensor is usually all you’ll need.
However, using the HC-SR04 outside is a different story. It is a pretty fragile device and can easily be damaged by dirt, or even high winds. And, above all, it is not waterproof.
For these circumstances you can use this sensor, in more weathered states, even outdoors.

Sensor Usage
Basic working principle
(1) using IO port TRIG trigger location, to the high level signal of at least 10us;
(2) module automatically sends 8 40KHz pulse, automatic detecting whether a signal returns;
(3) on signal return, a high level is output through the IO port ECHO, the time duration of the high level is ultrasonic from launch to return. The test distance = (high level time * speed of sound (340M/S)) /2;

FAQ
Why is the test data wrong? Voltage * Current = Power, But power is less than the actual test voltage * Current, Why is that?
Answer: There are three types of power:
Active Power (P represents / unit W)
Reactive power (Q represents / unit Var)
Apparent power (S represents / unit VA)
Here we only talk about Active Power, for others, please google it:
P = U * I * cosφ, cosφ it represents the power factor, purely resistive load (Such as incandescent, heater, etc.) the power factor is generally close to 1,Between the inductive and capacitive load load power factor 0-1. So purely resistive load test time, P is substantially equal to or close to U * I. When Inductive or capacitive load test (Such as refrigerators, washing machines, televisions, computers, etc.) P<U*I, As for how much to keep the power factor related to the specific, Different for each appliance power factor.

125KHz Serial UART RFID Card Reader (125KHz Serial card reader)
This is a radio frequency ID card reader module that can read the ID card's serial numbers. It can help to design intelligent access control systems. When the module sensed ID card, it will convert the card number into a 9-digit hexadecimal number, each digit of which will be converted into ASCII code. Then it adds a starting byte and 5 other bytes, so a total of 15 bytes output to the serial port. You can convert it into a decimal number that is the serial number engraved on the ID card.

2 Pcs LilyPad Button Connect Sensor Board Module for Arduino Power DIY KIT Momentary Push Button Electronic PCB Board Module (wearable buttons(2))
Description:
We designed this board to give the user a very discrete button without any edges. Button closes when you push it and opens when you release (momentary push button).
Each LilyPad was creatively designed to have large connecting pads to allow them to be sewn into clothing. Various input, output, power, and sensor boards are available. They're even washable!

INA219 I2C interface High Side DC Current Sensor Breakout power (INA219 I2C interface)
CJMCU-219 is a module with the I2C interface of zero drift and bi-directional current/power monitoring and control integrated circuit (IC), further expand the TI energy-saving electronic products.INA219 has the industry's highest precision and the small size, not only can monitor the pressure drop on the shunt resistor, sensing shunt power supply voltage, at the same time also can calculate the power.The device adopts the SOT23 packaging, but for the server, notebook computer, power supply, battery management and digital electric vehicle and telecommunication equipment measuring flu provide small, low cost solution.
INA219-40 c to 85 c temperature range and can realize the maximum error of 1% accuracy, maximum offset of 100 uV.The advantage of the high precision of the product in combination with 12 resolution, can help clients as much as possible, reduce the pressure drop on the shunt resistor, which can minimize the power loss and power consumption, and saving board space.The device epic of 26 bus voltage range of 0 V to V.
