PIR sensors, often referred to as, "Passive Infrared" or "IR motion"  sensors, enable you to sense motion. Everything emits a small amount of  infrared radiation (IR), and the hotter something is, the more radiation  it emits. PIR sensors are able to detect a change in average IR levels  of their detection zone (e.g. when a human enters a room, that room will  increase in temperature slightly) and hence sense motion. 

This  one's great, as it can be powered  via the Raspberry Pi's 5V output, and  be read directly from the Raspberry Pi's GPIO input (as the sensor has a  digital 3.3V output!)

This PIR includes an adjustable delay  before firing (approx 0.5 - 200 seconds), has adjustable sensitivity and  two M2 mounting holes! It runs on 4.5V-20V power (or 3V by bypassing  the regulator with a bit of soldering) and has a digital signal output   (3.3V) high, 0V low. Its sensing range is up to 7 meters in a 100  degree cone.

Setup with Raspberry Pi

DHT11 is the most common sensor that is usually used by students and makers out there. The main function of this sensor is to measure the temperature and humidity of the surroundings. The sensor is also factory calibrated and hence easy to interface with any microcontrollers like Arduino. The sensor can measure temperature from 0°C to 50°C and humidity from 20% to 90% with an accuracy of ±1°C and ±1%. So if you are looking to measure in this range then this sensor might be the right choice for you!

The DHT11 sensor can either be purchased as a sensor or as a module. Either way, the performance of the sensor is the same. The sensor will come as a 4-pin package out of which only three pins will be used whereas the module will come with three pins as shown below. The only difference between the sensor and module is that the module will have a filtering capacitor and pull-up resistor inbuilt so that you can just simply connect wires and start your project!



Pinout Configuration
 

• Vcc: Power supply 3.5V to 5.5V
• Signal: Outputs both Temperature and Humidity through serial Data
• Ground: Connected to the ground of the circuit

Features

• With calibrated digital signal output
• Adopt special digital module acquisition technology and temperature and humidity sensing technology to ensure high reliability and excellent long-term stability.
• The sensor is composed of a resistance liquid contact element and an NTC temperature measuring element and is connected to a high-performance 8-bit microcontroller. Therefore, the product has the advantages of high quality, ultra-fast response, strong anti-interference ability, and high-cost performance.
• The single-wire serial interface makes system integration simple and fast. Ultra-small size, low power consumption, and a signal transmission distance of more than 20 meters make it the best choice for any application, even the most demanding ones. The product is easy to connect and can be plugged directly into the sensor expansion board.

Application

• Measure temperature and humidity
• Widely used for IoT projects
• Local Weather station
• Automatic climate control
• Environment monitoring

Specifications 

• • Operating Voltage: 3.0V to 5.5V

This infrared obstacle/object detection sensor is super easy to use. It comes with a potentiometer to adjust the sensitivity. The output is a digital signal so it is easy to interface with any microcontroller such as Maker UNO, Mega, Leornado, Zero, 101, or even the Raspberry Pi or Raspberry Pi Zero. This infrared sensor offers simple, user-friendly, and fast obstacle detection via infrared reflection, it is non-contact detection. As it is based on light reflection, the detection varies with different surfaces. And any infrared source might also interfere with the detection.

It comes in a pair of Infrared emitter and receiver at the front of the module, whenever an object blocks the infrared source, it reflects the infrared and the receiver gets it and the signal goes through a comparator circuit on board. Depending on the threshold that is being adjusted, it will output logic LOW at the output pin and the green LED will light up to indicate the detection. Turning the onboard potentiometer clockwise will increase the sensitivity and further increase the detection range. Compatible with 5V or 3.3V power input.

Note: Please make sure that there is a gap between the emitter and the receiver so that the sensor can work properly.
