RFID Wristband (or Bracelet) have various design, it is light, colorful, smooth shape, easy to carry unconsciously, Waterproof RFID wristband is suitable for people underwater Comfortable.

How Much Data Can an RFID Tag Store?

An important element in how RFID wristbands work is storage capacity. The largest passive RFID tags can store up to 3720 bytes, or 3.72 kilobytes of information. That may seem like a small amount, but that is enough to store your name, address, credit card numbers, date of birth, and whatever identifying information the local administrator wants to track.

Ultra-high frequency tags can store up to 8 kilobytes of information, but such tags are typically reserved for use in the aerospace industry. For wristbands and access control systems, RFID tags typically are 3 kilobytes or smaller and do not contain sensitive information such as your social security number.

Data you sometimes find stored on RFID tags can include identification credentials, purchasing credits, vouchers, and even social media integration. So when you walk through a checkpoint, you can choose to have your activity posted to social media automatically. For hotels, an RFID system can even replace keycards for access control.

This looks like a potentiometer, but it’s an encoder switch.

It is a cascadable 360 ° rotary encoder switch with 20 pulses per revolution, and each pulse corresponds to a detent. There are LED lights set for each detent to allow users visually check the real-time status of the encoder.

For ease of use, the module is designed with I2C data output and configurable accuracy within 1~51 for every detent (set in the program). For instance, when it is set to 1, turn on one LED light by rotating 2.5 revolutions; when set to 51, then one LED light can be switched on by rotating one detent.

In order to apply to more scenarios, the encoder is equipped with a cascade function that enables to control of multiple output devices by occupying only one I2C interface, such as, simultaneously controlling light brightness, color, volume, speed, etc.

If you want to build a project where the machine can Sense the speed of the conveyer belt as well as the direction of movement, a rotary encoder is a must-have component. Keeping this in mind, A rotary encoder is a type of position sensor which is used for determining the angular position of a rotating shaft. It generates an electrical signal, either analog or digital, according to the rotational movement.

Orange 2500 PPR Incremental Optical Rotary Encoder is a hi-resolution optical encoder with quadrature outputs for increment counting. It will give 10000 transitions per rotation between outputs A and B. whereas the Z phase will produce one transition per rotation. A quadrature decoder is required to convert the pulses to an up count. The Encoder is built to Industrial grade.

Most Waterproof Ultrasonic Sensor Module aren’t waterproof which can be a problem if you need your project to withstand the elements outdoors. No need to worry anymore! We have developed waterproof & ultrasonic distance sensors with a waterproof sealed emitter. This sensor is suitable for outdoor applications such as car reversing sensors, security alarms, industrial inspection, etc.

This module is easy to use. A control port sends a high level above 10US, so you can wait for the high-level output at the receiving port. You can turn on the timer when there is an output. When this port goes low, you can read it. The value of the timer, at this time, is the time of the distance measurement, in order to calculate the distance. Such continuous cycle measurement, that is, you can reach the value of your mobile measurement.

This is an Arduino compatible piezo film vibration sensor. It is made up of flexible piezo film and converter board. The sensor is able to detect vibration, flexibility, impact and touch. The film is a flexible component comprising a 28 µm thick piezoelectric PVDF polymer film with screen-printed Ag-ink electrodes, laminated to a 0.125 mm polyester substrate, and fitted with two crimped contacts. As the piezo film is displaced from the mechanical neutral axis and bending creates very high strain within the piezo polymer, high voltages (about ±90V) are generated. When the assembly is deflected by direct contact, the device acts as a flexible “switch”, and the generated output is sufficient to trigger MOSFET or CMOS stages directly.

The module uses universal Gravity 3Pin interface that is easy to plug and play. It comes with Digital and Analog two output signals, which is  suitable for all kinds of different applications. The piezo vibration sensor is not only able to detect strong shocks, but also to detect slight vibrations. There is an on-board sensitivity adjustment potentiometer, you can adjust it to increase/decrease the output threshold value.

Meanwhile, the piezo film sensor has a wide dynamic range (0.001Hz~1000MHz) also guarantees an excellent measuring.
