How to Choose the Best Electronic Sensor Manufacturer

Electronic sensors are specially designed to detect any changes in the environment from distance to acceleration and to light. Also, electronic sensors help in sensing anything in our world. These sensors send any information it collects and send them to different electronics.  There is an endless range of them available.

Sensors are available in everyday devices. You will find sensors in lamps with touch sensation and touch-sensitive elevator buttons. They help in measuring real-world quantities and then convert them into an electrical signal. On the other hand, actuators, receive an electrical signal and then convert it into a physical form. Speakers and motors are a good example of actuators.

Sensors are now being used in a wide range of application. Sensors now offer more functions beyond traditional fields of temperature, flow measurement, or pressure. In today’s world, analog sensors like potentiometers and force-sensing resistors are commonly integrated.

The applications of sensors include medicine, cars, airplane, manufacturing, machinery robotics, and aerospace among others. Different sensors are available for measuring the chemical and physical characteristics of materials.

How do Sensors Work?

Sensors respond to any changes in physical conditions by changing their electrical properties. Therefore, the majority of artificial sensors solely depend on electronic systems to relay, capture, and analyze data about the environment. Also, the electronic systems mentioned here work based on the same principles as electrical circuits. Therefore, they must be able to regulate electrical energy flow.

A sensor helps in converting stimuli like motion, heat, sound and light into electrical signals. These electrical signals go through an interface in which they are converted into a binary code and then they pass this to a computer for processing.

A wide range of sensors functions as a switch, thereby regulating the flow of electric current that passes through the circuit. Also, switches are a core part of electronics. This electronic parts change the state a circuit. Sensors have several components which include diodes, transistors, and integrated circuits (chips). These components are included in the sensor circuits and as such, they function as switches. For example, a transistor uses small electrical current in a part of the circuit to help switch on a large electrical current in another circuit.

Most times, sensors make use of radiation like infrared radio waves, laser or light, ultrasonic waves to identify the changes and objects available in the environment. Sensors can do this if there is an energy source that helps them discharge radiation in to their target object.

Classification of Sensors


There are different classifications of sensors. However, we will be discussing the two main types of sensors which are analog sensors and digital sensors. The major difference between these two sensors is in how they output measured data.

Analog sensors

Analog sensors represent a quantity by creating analog signals. These sensors have less features. Also, these sensors offer a more continuous signal. Analog sensors are available in many types. The pressure sensor is an example of analog sensors. This sensor is usually integrated in labs and industries to manage gas or liquid pressure.

Digital sensors

Digital sensors generate a discrete signal which is a digital representation of a measurement. These sensors are known to provide binary output in zeros and ones. They are less expensive than analog sensors. In digital sensors, data conversion and transmission take place. Digital sensors are a better option as they have overcome the limitations of analog sensors. Also, these sensors are less vulnerable to electrical interruption and they feature lower design risk.

Digital sensors can measure ammonium concentration, conductivity, and PH levels. Since these sensors don’t have the limitations of analog sensors, they are widely used in applications like water purification and industrial systems.

Humidity sensors

These sensors measure the amount of relative humidity. They work with temperature sensor since it is important to know the temperature before measuring relative humidity. Relative humidity measures the percentage of water the air is holding when compared to the highest amount the air can hold.

The air will hold more water, when the temperature is higher. This indicates that temperature has a direct influence on relative humidity.

Temperature sensors       

The most commonly used type of sensor is temperature sensors. This is because a lot of microchips have built-in temperature sensors that are capable of shutting down a chip down if it overheats. Also, thermocouples, thermistors, and RTD’s are the commonest types of temperature sensors. Based on requirements, different types of sensors are integrated for measuring temperature in various applications.

Chemical sensors

Chemical sensors detect the different kinds of changes in liquid. Also, these sensors detect the variations in the air chemical. These sensors are usually integrated in commercially atmospheric observation. Chemi resistor, fluorescent chloride type, and chemical FET.

Ultrasonic sensors

These are transducers that estimate the characteristics of the target. Ultrasonic sensors are categorized into passive and active ultrasonic sensors. Active ultrasonic sensors produce high-frequency sound waves which the ultrasonic sensor receives for echo evaluation. Passive ultrasonic sensors are usually integrated for detecting ultrasonic noise.
