This SHARP distance sensor bounces IR off objects to determine how far away they are. It returns an analog voltage that can be used to determine how close the nearest object is. These sensors are good for short-range detection. • Infrared range finder 10cm (~4") to 80cm (~30") • Analog interface • Lead free, ROHS compliant • Replaces the discontinued GP2D12

The GP2Y0A710K infrared sensor is a new version of GP2Y0A700K which takes a continuous distance reading and reports the distance as an analog voltage with a distance range of 1m (39.3") to 5.5m (216.5"). The interface is 5-wire JST connector (included with pins) with dual Vcc, dual Gnd, and a single output voltage. Power, ground and signal wiring is enough to read a continuous analog voltage representing distance. A software lookup table can be implemented to translate the voltages to distances.

he smallest and easiest to use serial conversion circuit on the market! This board has one purpose in life - to convert RS232 to TTL and vice versa (TX and RX). This will allow a microcontroller to communicate with a computer. Shifter SMD is powered from the target application and can run at any voltage! That’s right - power the board at 5V and the unit will convert RS232 to 5V TTL. Power the board at 2.8V and the Shifter board will convert RS232 to 2.8V CMOS TTL. Includes two indicator LEDs for TX and RX. Runs from 300bps up to 115200bps.

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
