Get RFID Reader Writer NFC Module MFRC522 Board RobotDyn for Arduino - products that work with official Arduino boards Feature:   This RFID module base on MFRC522 IC and that can read and write Mifare's tags. The microcontroller and card reader uses SPI for communication. The card reader and the tags communicate using a 13.56MHz electromagnetic field. The RFID MFRC522 module supports MF1xxS20, MF1xxS70 and MF1xxS50 tags. The RFID MFRC522 module supports contactless communication and uses MIFARE higher transfer speeds up to 848 kBd in both directions. RFID MFRC522 has a compact design and small size 36x36mm. Power can supply 3.3V or 5V. This easy for connection to board with 5V, not need power regulator for 3.3V.The antenna is built into the board. And it has good sensitivity to a height of 25mm*tags not in the set. Documents:   Dimensional drawing: Click here to open Pinout: Click here to open   Package includes:   1 x RFID modules

Get Water Level Detection Sensor Liquid Level Controller Module for Automatic Drainage Device Level Controller Board Features:   1. Three color LED indicate low (red), medium (yellow),high (green) water, low water pumping or high-water pumping 2. Can be switched on and off when you press the function switch jump (not pressed) when low water relay (external pumps work),start adding water, the water level rises to a high level relay off (pump stopped working),until the water level drops below the low water level again relay again, the above process cycle. This feature is used in automatic water equipment,allowing the water level is maintained at a low level and high level between. 3. When the function switch when pressed, when the high-water relay (external solenoid valve),begins to drain, the water level drops below the low water relay off (solenoid valves stop working)until the water level rises again to the high.water relay pull again, the
