E18-D80NK Infrared Obstacle Avoidance Photoelectric Sensor
The E18-D80NK sensor is used to detect obstacles and objects. This sensor works based on transmitting infrared rays. First, the transmitter sends the rays in a direct path. This ray hits the obstacle and returns to the receiver. There is a potentiometer on this module that can be adjusted to change this detection distance from 3 to 80cm. In fact, with this sensor, the obstacle can be detected, but the distance cannot be calculated directly. There is also an LED on this sensor that turns off by detecting an obstacle. When there is an obstacle, the sensor output is HIGH, otherwise it is LOW. This sensor is used in robotics, parking sensor, RPM counting, etc. Note: If you turn the potentiometer clockwise, the detection distance will increase and vice versa. As this is an infra-red sensor it can be affected external sources of infra-red light such as sunlight.Maximum range will be affected by environmental conditions and reflectiveness of sensed object Electrical Characteristics:Supply Voltage: 5VDCSupply Current: The 100mARange: 3-80CM Output:High = triggered LED:On when not triggered Applications:1.

Raindrops Detection Sensor Module
The raindrop sensor module is used for rain detection. It is also for measuring rainfall intensity. The module includes a rain board and a control board that are separate for more convenience. It has a power indicator LED and an adjustable sensitivity though a potentiometer. The module is based on the LM393 op amp. It includes a printed circuit board(control board) that & ldquo;collects & rdquo; the rain drops. As rain drops are collected on the circuit board, they create paths of parallel resistance that are measured via the op amp. The lower the resistance (or the more water), the lower the voltage output.Conversely, the less water, the greater the output voltage on the analog pin. A completely dry board for example will cause the module to output five volts.

HC-06 Bluetooth Module
The HC-06 bluetooth module is a slave bluetooth module designed for wireless serial communication. It is a slave module meaning that it can receive serial data when serial data is sent out from a master bluetooth device(device able to send serial data through the air: smart phones, PC).When the module receives wireless data, it is sent out through the serial interface exactly at it is received. No source code specific to the Bluetooth module is needed at all in the arduino chip. An app on the phone is used to send out inputs to the module which receives and then transfers this to the arduino. The arduino and actuators in turn responds accordingly, as specified in the source code. When the module is not in a paired state, the LED on the module blinks rapidly whereas when paired with the app on the phone, the LED on the module is a steady red. The HC-06 module has four pins which are all required in order to make a connection with the arduino UNO. The VCC pin is where the module receives its input voltage and is thus connected to the 5V pin on the arduino. The GND on the module is the ground pin which connects to the ground pin on the arduino. In other words, it is the reference point from where all the other voltages are measured. The RXD and TXD are the recieve and the transfer pins respectively on the module. The module receives the serial data from the master device (smartphone) through the RXD pin and then transfers that data to the arduino using the TXD pin. The TXD pin on the module is connected directly to the RX pin on the arduino whereas the RXD pin of the module is connected to the TX pin on the arduino using a voltage divider circuit as the RXD on the module can only support voltage upto 3.3V.
