The TSL2561 is an inexpensive, yet sophisticated, light sensor. Unlike simpler sensors, like photoresistors and photodiodes, the TSL2561 incorporates both infrared and visible light sensors to better approximate the response of the human eye. Because the TSL2561 is an integrating sensor (it soaks up light for a predetermined amount of time), it is capable of measuring both very small and very large amounts of light.

The Sound Recorder Module uses the ISD1760 Chip to record and store voice signals. ISD1700 series recording chip is a kind of high integration, high performance chip. This module can be multiple recording, the sampling rate can be set to 6k or 8k by the on-board resistor. There are also some inside sounds to remind the user working state of the module, such as record beginning, record stopping, record erasing , etc. The recording data is stored in the FLASH, without any compression to ensure a good quality. You can easily control this module manually or by Arduino. There are some keys on the module including “REC”,”PLAY”,”EARSE”, you can control the module with these keys.

This module directly connects to any microcontroller UART or through a RS232 converter to PC.It gives UART/Wiegand26 output. This RFID Reader Module works with any 125 KHz RFID tags 1.Specifications 5VDC through USB (External 5V supply will boost range of the module) Current: <50mA Operating Frequency: 125Khz Read Distance: 10cm Size of RFID reader module: 32mm(length) * 32mm(width) * 8mm(height) 2. RS232 interface format: 10 ASCII DATA (card no.) 2 ASCII DATA (XOR result) E.g. Card number is 4500C5D1E9B8 read from reader then the card number on card will be as below. 45 - Preamble 00C5D1E9 value in Hex = 12964329. / B8 is XOR value for (45 XOR 00 XOR C5 XOR D1 XOR E9) Hence number on the card is 0012964329. 1. Data baud rate: 9600 bps 2. Data bit 8 bits 3. Parity check: None 4. Stop bit
