PPD42NS is a photoelectric sensor that detects the concentration of dust in the air and thus shows the quality of the air, using light reflection. The PM (eng. Particulate Matter) level in the air shows the amount of physical particles, and the label PM2.5 indicates particles smaller than 2.5um. This sensor provides data collectively, so it will be extremely useful in projects measuring the quality and purity of the air.

This sensor has one fototransistor and one fotodiode in its package. Fotodiode has 2 pins (anode and cathode) which are used to generate an infrared signal. Fototransistor also has 2 pins (collector and emitter) that are used to read the infrared signal that the fotodiode generates. Sensor is most commonly used to read distances that reflects in front of the sensor.

The MH-Z19 is a sensor that uses the non-dispersed infrared principle to detect CO2 in the air. It has built-in temperature compensation and high sensitivity to gas detection, and therefore has extremely accurate readings, and its outputs are on UART and PWM. It consumes little electricity and has a long service life.

NTC (Negative Temperature Coefficient) is a  resistor with variable resistance that changes depending on the temperature. The advantage of NTC is that it can measure a large temperature range, and measuring it with a voltage divider is very easy.

PMS7003 is a kind of digital and universal particle concentration sensor, which can be used to obtain the number of suspended particles in the air, i.e. the concentration of particles, and output them in the form of digital interface. This sensor can be used with different gadgets related to the concentration of particles in the air.

Load cell is a small device that is able to weigh the load on it. Due to the load, it provides very small output voltages that need to be amplified (eg using op-amp or ADC with a built-in op-amp) to find the use for the module. It incorporates two invariable two variable resistors connected to the Wheatstone Bridge. This sensor is made from high-quality materials, so it does not get affected by high temperature or continous load. You need to connect it with the HX711 to read information with Croduino.

The dust sensor inside has an infrared LED and an IR receptor. This allows it to detect even the smallest interruption of the light flux from the diodes to the detector and to register this as a dust particle. It is also effective in detecting other finer particles, such as those found in cigarette smoke. It gives an analog value as output, which you can connect to the analog input of a microcontroller and accurately measure air quality.

This motion sensor uses microwaves, based on the radar doppler effect, to detect warm bodies in motion. Therefore, it can be used as an alternative to the PIR sensor, the advantage being that it does not require optical visibility as a PIR sensor, and the disadvantage is that it detects objects at a smaller distance from the PIR.

The water level sensor allows you to detect the height of water or some other liquid in the tank. This float sensor works on the principle of magnets and magnetic (reed) switches. Usually, it is mounted on the bottom or top of the tank, and when in water, the floating part with a magnet, triggers the magnetic switch. This alteration can be detected and trigger a certain action; eg filling the tank or launch alert.

The Shunt Resistor is a special type of resistor with small resistance which allows large currents to pass through it. This is useful for measuring the current in a circuit: due to the Ohm’s law and voltage drop on the shunt resistor, we can know exactly which current passes through it. For example, for this resistor whose maximum current is 50A, the voltage drop at that current will be exactly 75mV (0.075V). Using a precise ADC, we can accurately measure the current of our consumer or power source.
