Current Sensor 20A

Overview
The ACS712 provides economical and precise solutions for AC or DC current sensing in industrial, commercial, and communications systems. The device package allows for easy implementation by the customer. Typical applications include motor control, load detection and management, switchmode power supplies, and overcurrent fault protection. The device is not intended for automotive applications.

Current Sensor 20A:
Features:
  • Low-noise analog signal path
  • Device bandwidth is set via the new FILTER pin
  • 5 μs output rise time in response to step input current
  • 80 kHz bandwidth
  • 1.2 mΩinternal conductor resistance
  • 5.0 V, single supply operation
  • Output voltage proportional to AC or DC currents

Finger Print Sensor (Serial Data)



Overview
Fingerprint processing includes two parts: fingerprint enrollment and fingerprint matching (the matching can be 1:1 or 1:N). When enrolling, user needs to enter the finger two times. The system will process the two time finger images, generate a template of the finger based on processing results and store the template. When matching, user enters the finger through optical sensor and system will generate a template of the finger and compare it with templates of the finger library. For 1:1 matching, system will compare the live finger with specific template designated in the Module; for 1:N matching, or searching, system will search the whole finger library for the matching finger. In both circumstances, system will return the matching result, success or failure.

Ultra Sonic Ranging Sensor

Overview
Ultrasonic sensor provides stable and accurate distance measurements from 2cm to 450cm. It has an focus of less than 15 degrees and an accuracy of about 2mm.

Ultra Sonic Ranging Sensor:
Description:


This sensor uses ultrasonic sound to measure distance just like bats and dolphins do. Ultrasonic sound has such a high pitch that humans cannot hear it. This particular sensor sends out an ultrasonic sound that has a frequency of about 40kHz. The sensor has two main parts: a transducer that creates an ultrasonic sound and another listens to it's echo. To use this sensor to measure distance, the robot's brain must measure the amount of time it takes for the ultrasonic sound to travel.
