Introducing our 13.56MHz RFID Key Fob ? a compact marvel designed for seamless and secure access control. This key fob operates on the widely used 13.56MHz frequency, ensuring compatibility with a variety of RFID systems.
The Raindrops Detection sensor module is used for rain detection. It is also for measuring rainfall intensity. Rain sensor can be used for all kinds of weather monitoring and translated into output signals and AO.
Raindrops Detection Sensor Module Rain Weather Module for Arduino, etc. Rain sensor can be used to monitor a variety of weather conditions and turned into several fixed output signal and Analog output.
It includes a printed circuit board (control board) that ?collects? the raindrops. As raindrops are collected on the circuit board, they create paths of parallel resistance that are measured via the op-amp. The lower the resistance (or the more water), the lower the voltage output. Conversely, the less water, the greater the output voltage on the analog pin. A completely dry board, for example, will cause the module to output 5V.
RC522: 13.56MHz RFID Reader/Writer with Cards The kit includes a 13.56MHz RF reader/writer module that uses an RC522 IC along with two S50 RFID cards. The MF RC522 is an extremely integrated transmission module that operates at 13.56 MHz for contactless communication. RC522 is compatible with MIFARE/ISO 14443A mode.
