Water Coffee Flow Sensor Switch Meter Flowmeter sensor Counter flow indicator caudalimetro 0.3-6L/min YF-S401 white G1/4
Water flow sensor consists of a plastic valve body, a water rotor, and a hall-effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall-effect sensor outputs the corresponding pulse signal. This one is suitable to detect flow in water dispenser or coffee machine.
- Compact, Easy to Install
- High Sealing Performance
- High Quality Hall Effect Sensor
- RoHS Compliant
Wearable solder Time II Spikenzielabs
The Solder : Time II is the latest version of our Solder : Time watch kit. This new version is even more hackable than ever. The on board microcontroller in this model is the very popular ATmega328P used in many of the current versions of Arduino. In fact, you can reprogram your watch using the same Arduino IDE software that you use for a regular Arduino.
The Solder : Time II has a much more impressive display. Four 5x7 LED matrix modules gives you control of a 7x20 matrix for a total of 140 LEDs!
The new LED matrix allows for an amazing amount of information to be displayed; time, date, month, words, scrolling messages, graphics, special characters ... the possibilities are endless. The ST2 also has a piezo buzzer for the alarm. You can also use it to add sounds to you custom programming or even games!
WiFi Module - ESP8266 (Genuine)
The ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each ESP8266 module comes pre-programmed with an AT command set firmware, meaning, you can simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers (and that's just out of the box)! The ESP8266 module is an extremely cost effective board with a huge, and ever growing, community.
This module has a powerful enough on-board processing and storage capability that allows it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, including the front-end module, is designed to occupy minimal PCB area. The ESP8266 supports APSD for VoIP applications and Bluetooth co-existance interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions, and requires no external RF parts.
XBee 1mW Trace Antenna - Series 1 (802.15.4) (Genuine)
This is the very popular 2.4GHz XBee module from Digi. These modules take the 802.15.4 stack (the basis for Zigbee) and wrap it into a simple to use serial command set. These modules allow very reliable and simple communication between microcontrollers, computers, systems, really anything with a serial port! Point to point and multi-point networks are supported.
XBee 2mW Wire Antenna - Series 2
This is the XBee XB24-Z7WIT-004 module from Digi. Series 2 improves on the power output and data protocol. Series 2 modules allow you to create complex mesh networks based on the XBee ZB ZigBee mesh firmware. These modules allow a very reliable and simple communication between microcontrollers, computers, systems, really anything with a serial port! Point to point and multi-point networks are supported.
These are essentially the same hardware as the older Series 2.5, but have updated firmware. They will work with Series 2.5 modules if you update the firmware through X-CTU.
XBee 3 Module - PCB Antenna (Genuine)
After years of popularity with the XBee Series 1 and XBee Series 2, we now have the XBee Series 3 which brings the best of both worlds. XBee 3 not only handles 802.15.4, and ZigBee, but also BLE protocols and you can now talk to the modules over UART or SPI as well. With a 200ft indoor range, or 4000ft outdoor/line-of-sight range, you can set up a mesh network to talk to or communicate with various devices around your house, work, or other area.
This module has the familiar XBee package while sporting a PCB Antenna. You also get a built in microcontroller so you can also configure and program the modules using MicroPython as well as Digi's XCTU software. With a HCS08 CPU running at up to 50.33MHz, 15x digital I/O pins, and 4x 10-bit ADC pins these modules can even hold their own as a microcontroller.
XL6009 dc dc Auto Boost Buck Adjustable Step Up Step Down Converter Module Solar 1.25-36V Voltage Board MOSFET Switch DSN6000AUD
Auto start voltage will be pulled down to 7V less or smaller engine at high speed when the voltage up to 15V or higher. For 12V electrical work hard at work, this automatic buck module solves this problem , regardless of the input voltage is 5V or 12V or 32V, the output can be stabilized at 12V.
ZX Distance and Gesture Sensor (Genuine)
The ZX Distance and Gesture Sensor is a touchless sensor that is capable of looking for simple gestures. Developed in conjunction with XYZ Interactive, the sensor uses their GestureSense®technology to recognize the distance of an object away from the sensor up to about 12 inches (30cm, referred to as the “Z” axis) and the location of the object from side to side across the sensor in about a 6-inch (15cm) span, referred to as the “X” axis. You will be able to use I2C or UART to communicate with the ZX Sensor via a microcontroller or computer.
The ZX Sensor works by bouncing infrared (IR) beams of light from the two LEDs on either side off of an object above the sensor. The bounced light returns to the receiver in the center of the sensor, and a microcontroller on the back of the sensor interprets the data. With these IR pieces you will easily be able to ascertain both the Z axis and the X axis of an object (hence the name). In addition to providing Z and X axis data about an object, the ZX Sensor is capable of detecting simple gestures. We have also clearly labeled all the pin outs on the board, as well as signifying if they are needed in I2C or UART communication.
