The DS18B20 is a 1-wire programmable Temperature sensor from maxim integrated.
It is widely used to measure temperature in hard environments like in chemical solutions, mines or soil etc.
The constriction of the sensor is rugged and also can be purchased with a waterproof option making the mounting process easy.
It can measure a wide range of temperature from -55°C to +125° with a decent accuracy of ±5°C.
Each sensor has a unique address and requires only one pin of the MCU to transfer data so it a very good choice for measuring temperature at multiple points without compromising much of your digital pins on the micro controller.

650nm Laser sensor Module 6mm 5V 5mW Red Laser Dot Diode Copper Head KY-008
This 5V laser head is very easy to use, you can use Arduino control, make controllable laser pointer, theft detection, etc. interesting application devices.
As long as the laser can not point to itself or other eyes, even if the box is closed, the laser will have to open the possibility of error.
The laser is not a toy, does not give children, mental shortage, for people who do not know the use of laser characteristics, in this case, it can easily lead to injury.
The use of lasers must wear special glasses, for the invisible laser, this point is especially important.
The laser cannot shine on vehicles, airplanes and other transportation vehicles.

The Infrared Barrier Module is able to adapt to the environment light very well. Having a pair of infrared transmitter and receiver tube, the transmitter consistently emits a certain frequency. When an obstacle with reflective surface is encountered, the infrared reflected back is received by the receiver & sent to the comparator circuit for processing. The green light will lit and output digital signal (low). The detection range can be adjusted via the potentiometer knob.
