20A Range Current Sensor Module ACS712 (20A Range Current Sensor Module ACS712)
Product Description :
The 20A Range Current Sensor Module ACS712 consists of a precise, low-offset, linear Hall circuit with a copper conduction path located near the surface of the die. Applied current flowing through this copper conduction path generates a magnetic field in which the Hall IC converts into a proportional voltage.
Sensing and controlling current flow is a fundamental requirement in a wide variety of applications including, over-current protection circuits, battery chargers, switching mode power supplies, digital watt meters, programmable current sources, etc.
This ACS721 current module is based on the ACS712 sensor, which can accurately detect AC or DC current.
The maximum AC or DC that can be detected can reach 20A, and the present current signal can be read via analog I / O port of Arduino.
Note: The color of the product may vary. while shipping you may get any one of them.

MPR121 Breakout V12 Capacitive Touch Sensor Controller Module I2C keyboard (MPR121)
Description : This MPR121 is a capacitive touch sensor controller driven by an I2C interface. The chip can control up to twelve individual electrodes, as well as a simulated thirteenth electrode The MPR121 also features eight LED driving pins, when these pins are not configured as electrodes, they may be used to drive LEDs. There are four jumpers on the bottom of the board, all of which are set (closed) by default. An address jumper ties the ADD pin to the ground, meaning the default I2C address of the chip will be 0x5A. If you need to change the address of the chip (by shorting ADD to a different pin), make sure you open the jumper first. Jumpers also connect SDA, SCL, and the interrupt pin to 10k pull-up resistors. If you do not require the pull-up resistors you can open the jumpers by cutting the trace connecting them.
