IR Infrared Transmitter Sensor Module
This Infrared Obstacle Avoidance Sensor Module is an inexpensive solution to avoidance detection for robotics and other electronics uses. It comes as an assembled module, as shown above, there are only four pins: 5-volts, GND, output, and EN. Output is an active LOW and has an onboard status LED. It’s very easy to interface directly with micro-controllers. It also works with the Raspberry Pi with a voltage range of 3-6 volts. Connect Vcc to 3-volts.
The enable pin “EN” will disable the device when HI (Vcc) and enable when LO (GND). The onboard jumper can be left open to allow external control of enable/disable of the module. There are two potentiometers on the module one controlling operating frequency (centred at 38 kHz) the other controlling intensity. The detector was designed for 38 kHz and the onboard oscillator circuit is based on a 555 timer.

MPR121 Breakout V12 Capacitive Touch Sensor Controller Module I2C keyboard (MPR121)
Model NumberMPR121
ChannelsN/A
Input Voltage2.5 to 3.6 V DC
Response TimeN/A
InterfaceI2C
ColorBLACk
Operating Temperature-20 to 70 deg C
MaterialAlloy Plastic

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.

Features of MPR121 Breakout V12 Capacitive Touch Sensor Controller Module:
  1. Capacitive touch sensor controller driven by an I2C interface.
  2. Can control up to twelve individual electrodes, as well as a simulated thirteenth electrode.

This Hall Sensor Module used Hall Sensor - A3144E. The Hall Sensor measures the Hall Effect, which is a production of a voltage difference across an electrical conductor, transverse to an electric current in the conductor as well as a magnetic field perpendicular to the current. The output of the Hall sensor switches low and turns on when a magnetic field perpendicular to the Hall sensor exceeds the BOP threshold, and it switches high and turns on when the magnetic field disappears. And the comparator circuit that makes the output signal more reliability.
