5.12V Battery
Materials used to make the Temperature Sensor circuit:
01. Thermistor
A thermistor is a type of resistor Systems whose resistance depends on temperature. A thermistor is a combination of thermistor and resistor. It is commonly used as a temperature sensor. It is made of temperature-sensitive material.Thermistors typically operate in a temperature range of -55°C to +200°C. A thermistor is made of semiconducting material ie its resistance is between conductor and insulator. It is made of various metal oxides such as manganese, cobalt, copper, iron and uranium in various forms (beds, rods, discs).
02. Resistor
The main function of a resistor is to block current flow or drop voltage in an electronic circuit. In short, the function of a resistor is to prevent the flow of electricity. When we know about electronics, the first name that comes up is a resistor. It is basically a common Material of electronics.This element is used in every electronic circuit. A resistor is a very familiar element to those who work with electronics. It has a special function. Resistance is denoted by R. Its unit is ohm (Ω). The figure below shows some of the resistor symbols used on various circuit boards and circuit diagrams.
03. Transistor
A transistor is a semiconductor device, commonly used as an amplifier and electrically controlled switch. Transistors are used as the basic building blocks in computers, cellular phones and all other modern electronics. In terms of the structure of the electronic transistor, the transistor is made by combining two diodes.For example, if you know that a diode has a p-n junction, adding another p to it will create a p-n-p transistor. This is nothing more than an initial idea. Currently, transistors are not made this way. Transistors are made in more advanced ways.
04. 12v DC Fan
12V DC Cooling Fan 2 Inch 50mm, Direct Current Fan, and DC Fan are driven with constant quality potential like battery voltage. It features maintenance-free double ball long service life, bearings and adequate heat dissipation air volume and air pressure. Generally the electricity we use at home is AC and the output of the IPS is AC though it accepts battery (DC) supply during load shedding.If you can't do it yourself, make a bridge rectifier and connect it to the motor (fan) using a 16-volt 100mf electrolytic capacitor.Low fan speed can be caused by excessive IPS power you are using or a weak capacitor in your fan.
05. 12v Battery
A 12-volt battery is an irregular battery used in certain electronic applications. Among all types of batteries, the 12-volt battery is one that looks very different depending on its use. It can be big or small, heavy or light. 12-volt batteries are commonly used in RVs, boats, and other automobile systems.From a technical perspective, a battery uses one or more cells to allow a chemical reaction that creates a flow of electrons in a circuit.
