HC SR-04 - Product features:

Ultrasonic ranging module HC - SR04 provides 2cm - 40cm the ranging accuracy can reach to 3mm.
The modules includes ultrasonic transmitter, receiver and control circuit. The basic principle of work:

(1) Using IO trigger for at least 10us high level signal,
(2) The Module automatically sends eight 40 kHz and detect whether there is a pulse signal back.
(3) IF the signal back, through high level , time of high output IO duration is the time from
sending ultrasonic to returning.Test distance = (high level time×velocity of sound (340M/S) / 2.

RedBot Sensor - Line Follower

Description: The Line Follower sensor is an add-on for your RedBot that gives your robot the
ability to detect lines or nearby objects. The sensor works by detecting reflected light coming
from its own infrared LED. By measuring the amount of reflected infrared light, it can detect
transitions from light to dark (lines) or even objects directly in front of it.
The sensor has a 3-pin header which connects directly to the RedBot Mainboard via female to
female jumper wires. Use the included RedBot library to detect lines or objects. A mounting hole
lets you easily connect one or more of these to the front or back of your robot chassis.

Dimensions: 0.32 x 1.18 " (8.22 x 30.14 mm)
Features:

• 5VDC operating voltage
• Mounting hole
• 25mA supply current
• Optimal sensing distance: 0.125" (3mm)

Description: The ML8511 breakout is an easy to use ultraviolet light sensor. The MP8511 UV (ultraviolet) Sensor works by outputing an analog signal in relation to the amount of UV light that’s detected. This breakout can be very handy in creating devices that warn the user of sunburn or detect the UV index as it relates to weather conditions.

This sensor detects 280-390nm light most effectively. This is categorized as part of the UVB (burning rays) spectrum and most of the UVA (tanning rays) spectrum. It outputs a analog voltage that is linearly related to the measured UV intensity (mW/cm2). If your microcontroller can do an analog to voltage conversion then you can detect the level of UV!

Description: This is a breakout board for Freescale’s MPR121QR2. The 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 a four jumpers on the bottom of the board, all of which are set (closed) by default. An address jumper ties the ADD pin to 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 don’t require the pull-up resistors you can open the jumpers by cutting the trace connecting them.

There is no regulation on the board, so the voltage supplied should be between 2.5 and 3.6VDC. The VREG pin is connected through a 0.1uF capacitor to ground, which means, unless you modify the board, you can’t operate the MPR121 in low-supply voltage mode (1.71-2.75VDC).

Description: This non-invasive current sensor (also known as a “split core current transformer”) can be clamped around the supply line of an electrical load to tell you how much current is passing through it. It does this by acting as an inductor and responding to the magnetic field around a current-carrying conductor. By reading the amount of current being produced by the coil, you can calculate how much current is passing through the conductor.

This particular current sensor will measure a load up to 30 Amps which makes it great for building your own energy monitor to keep your power usage down, or even building an over-current protection device for an AC load. This sensor does not have a load resistor built in, so in most cases it will be necessary to place a resistor across the output to convert the coil’s induced current to a very small measurable voltage.
