This is TCRT 5000 Dual Channel Line Tracking sensor module.

This IR reflective sensor Module used TCRT5000 IR Sensor to detect color and distance. This sensor module consists of an IR transmitter & an IR receiver. IR Transmitter continuously emits IR signal which is then reflected by an obstacle and is then detected by the IR receiver.

TCRT5000 Infrared Reflective Sensor Module is often used in line following robots, object sorting Robots because this module can sense if a surface is white or black. The measuring distance range from 1mm to 8mm and the central point is about 2.5mm.

There is also an onboard potentiometer to adjust the sensitivity. The infrared diode will be emitting the infrared continually when the module is powered ON, when the emitted infrared light has not been reflected or the strength is not big enough, the receiver diode will in the off state and output pin i.e. DO will be LOW.

Package Includes :

1 x RTC DS1307 24C32 Real-Time Clock Module

Pin Description of DS1307:

Pin 1, 2: Connections for standard 32.768 kHz quartz crystal. The internal oscillator circuitry is intended for operation with a crystal having a specified load capacitance of 12.5pF. X1 is the input to the oscillator and can alternatively be connected to an external 32.768 kHz oscillator. The output of the internal oscillator, X2 is drifted if an external oscillator is connected to X1.

Pin 3: Battery input for any standard 3V lithium cell or another energy source. Battery voltage should be between 2V and 3.5V for suitable operation. The nominal write-protect trip point voltage at which access to the RTC and user RAM is denied is set by the internal circuitry as 1.25 x VBAT nominal. A lithium battery with 48mAhr or greater will backup the DS1307 for more than 10 years in the absence of power at 25ºC. UL recognized to ensure against reverse charging current when utilized as a part of conjunction with a lithium battery.

Pin 4: Ground.

Pin 5: Serial data input/output. The input/output for the I2C serial interface is the SDA, which is the open drain and requires a pull-up resistor, allowing a pull-up voltage to 5.5V. Regardless of the voltage on VCC.

Pin 6: Serial clock input. It is the I2C interface clock input and is used in data synchronization.

Pin 7: Square wave/output driver. When enabled, the SQWE bit set to 1, the SQW/OUT pin outputs one of four square-wave frequencies (1Hz, 4 kHz, 8 kHz, and 32 kHz). This is also an open drain and requires an external pull-up resistor. It requires the application of either Vcc or Vb at to operate SQW/OUT, with an allowable pull-up voltage of 5.5V and can be left floating, if not used.

Pin 8: Primary power supply. When the voltage is applied within normal limits, the device is fully accessible and data can be written and read. When a backup supply is connected to the device and VCC is below VTP, read and writes are inhibited. However, at low voltages, the timekeeping function still functions.

Product Details:

1. You can also use the IICLCD1602 LCD to display voltage.
2. By 3P connector, connect this module with the expansion of board Arduino
3. Voltage input range: DC 0-25 V
4. Voltage detection range: DC 0.02445 V  to 25 V
5. Voltage analog resolution : 0.00489 V

This is a simple but very useful module which uses a potential divider to reduce an input voltage by a factor of 5. The Voltage Detection Sensor Module 25V allows you to use the analog input of a microcontroller to monitor voltages much higher than it capable of sensing.

For example with a 0-5V analog input range, you are able to measure a voltage up to 25V. The module also includes convenient screw terminals for easy and secure connection of a wire.

This module is based on the principle of resistive voltage divider design, can make the red terminal connector input voltage to 5 times smaller. Arduino analog input voltages up to 5 v, the voltage detection module input voltage not greater than 5Vx5=25V (if using 3.3V systems, input voltage not greater than 3.3Vx5=16.5V).

Arduino AVR chips have 10-bit AD, so this module simulates a resolution of 0.00489V (5V/1023), so the minimum voltage of input voltage detection module is 0.00489Vx5=0.02445V.

Note:

Keep in mind, you are restricted to voltages that are less than 25 volts.   More than that and you will exceed the voltage limit of your Arduino input.

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 do not 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 not operate the MPR121 in low-supply voltage mode (1.71-2.75VDC).

Product Details:

You can use this A88 Metal detector non-contact metal induction detection module as a metal detector. When it approaches any metal, it makes a sound.

This is a module specifically designed to detect metal. The module operates by inducing currents in metal objects and responding when it occurs. A nice onboard buzzer signals when it detects something and an onboard potentiometer allow adjustment of sensitivity.

The power cables of the Metal detector non-contact metal induction detection module will need soldering on for the module to function, positive to the outside of the module and negative between the potentiometer and an electrolytic capacitor.

Features :

1. V+ Connect to power positive
2. V- connect to power negative
