What is a sensor?

A sensor is a device that can sense, detect or measure external information such as physical quantities, chemical quantities or biological quantities, and convert it into recognizable and processable electrical signals or other forms of signals.

As a core component in modern science and technology, and industry, sensors are like an extension of human "five senses", giving machines and systems the ability to perceive the environment, and are the key foundation for achieving automated and intelligent control.

What Types of Sensors are Available?

Photoelectric Sensors

Our industrial photoelectric sensors are a prime example of advanced sensing technology. Photoelectric sensors are sensors that use light signals as a detection medium based on the principle of the photoelectric effect to convert physical quantities such as the existence, position, distance, shape or surface characteristics of a target object into electrical signal outputs.

As a core detection element in the fields of industrial automation, intelligent manufacturing and the Internet of Things, it achieves high-precision, high-speed and high-reliability environmental perception through non-contact measurement.

Photoelectric sensors

Inductive Proximity Sensors

Inductive proximity sensors are non-contact detection devices based on the principle of electromagnetic induction.

They can output switch or analog signals by sensing the presence, position or motion of metal target objects. Their core advantage is that they can stably detect metal without physical contact.

Inductive proximity sensors

Capacitive Proximity Sensors

Capacitive Proximity Sensors are non-contact detection devices based on the principle of capacitance change. They can accurately determine the existence, position, material or distance of an object by sensing the capacitance disturbance between the target object and the sensor electrode. Its core advantage is that it can penetrate non-metallic media (such as plastic, glass, liquid) to detect targets without physical contact.

It is widely used in industrial automation, consumer electronics, automobile manufacturing and smart home. A common question is what is the difference between inductive and capacitive proximity sensors —the key difference lies in their ability to detect non-metallic materials, which capacitive sensors can do.

Pressure Sensors

As a core industrial sensor supplier , we offer a wide range of pressure sensors . What is pressure sensors ? They are devices that can convert pressure (gas or liquid pressure) into measurable electrical signals (voltage, current, resistance, frequency, etc.). Their essence is to sense changes in environmental pressure and output quantitative signals to achieve real-time monitoring and control of pressure parameters.

As core sensor devices in the fields of industrial automation, aerospace, automotive electronics, medical equipment, etc., pressure sensors have become a key bridge connecting the physical world and digital systems through the precise conversion of physical quantities to electrical signals.

Limited Swtiches

Our limit switch products are also known as travel switches or position switches. They are mechatronic devices that implement signal switching based on mechanical contact action. Their core function is to detect the limit position or preset travel of mechanical moving parts and output switch signals to control the circuit on and off or trigger system response.

As a key control element in the fields of industrial automation, mechanical equipment and safety protection, limit switches have become the core components for ensuring the safe operation of equipment and realizing programmed control by converting physical displacement into electrical signals.

How to select industrial pressure sensors?

How to select industrial pressure sensors?

Select the sensor type according to your needs (such as temperature sensor DS18B20, ultrasonic sensor HC-SR04, etc.). Confirm the parameters of the sensor (range, accuracy, output type: analog/digital, power supply voltage, etc.).

Connect the power supply according to the sensor specifications (commonly used 5V or 3.3V). To output analog signals, connect to the analog input pins of the development board (such as A0-A5 of Arduino). To output digital signals (such as I2C, SPI, single bus), connect to digital pins or dedicated communication interfaces. Make sure the sensor and the controller share the same ground (GND).

What is the difference between the "sensitivity" and "resolution" of a sensor?

  • Sensitivity: The ratio of the sensor output change to the input change (e.g. 10mV voltage output for every 1°C temperature change). The higher the sensitivity, the stronger the response to small signals.
  • Resolution: The minimum input change that the sensor can detect (e.g. temperature resolution is 0.1°C). The higher the resolution, the finer the measurement.
  • Impact: High sensitivity may introduce noise, and high resolution requires a high-precision ADC (analog-to-digital converter).

How to design a sensor signal conditioning circuit?

How to design a sensor signal conditioning circuit?

Signal conditioning circuits are used to optimize sensor output signals, usually including:

  • Amplification: Use operational amplifiers (such as instrumentation amplifiers) to amplify weak signals (such as mV-level thermocouple output);
  • Filtering: Use RC low-pass filtering to remove high-frequency noise (such as 50Hz power frequency interference);
  • Analog-to-digital conversion (ADC): Convert analog signals into digital signals for microprocessor processing.
What are the calibration methods for sensors?

What are the calibration methods for sensors?

  • Factory calibration: Calibration with high-precision equipment before leaving the factory, high accuracy but high cost (such as industrial pressure sensors);
  • Field calibration: Users calibrate regularly through standard sources, high flexibility but manual dependence (such as pH sensors);
  • Self-calibration: Built-in reference signal or algorithm automatic correction (such as MEMS gyroscope), suitable for long-term unattended scenarios.
How does a fiber optic sensor work?

How does a fiber optic sensor work?

  • Fiber Bragg Grating (FBG): The grating reflects a specific wavelength, and the strain or temperature change will change the reflected wavelength, achieving high-precision measurement.
  • Raman scattering: Using the relationship between scattered light intensity and temperature to achieve long-distance distributed temperature monitoring.
  • Advantages: Anti-electromagnetic interference, high pressure/high temperature resistance (such as oil well monitoring), and simultaneous measurement of multiple parameters."
What are the common types of sensors?

What are the common types of sensors?

  • Temperature sensors (such as thermistors): detect ambient temperature;
  • Pressure sensors (such as piezoelectric): measure gas or liquid pressure;
  • Photoelectric sensors (such as photoresistors): sense light intensity;
  • Acceleration sensors (such as MEMS accelerometers): detect the motion state of objects;
  • Gas sensors (such as MQ series): identify specific gas concentrations (such as CO₂).
How do capacitive sensors detect non-metallic materials?

How do capacitive sensors detect non-metallic materials?

  • By detecting changes in capacitance between electrodes.
  • When non-metallic materials (such as plastics, liquids) enter the electric field, the change in dielectric constant causes a change in capacitance, which in turn triggers a signal (such as touch screens, liquid level sensors).

Connection cable

Connection cable

Function: Used to connect the sensor to the data acquisition device, controller or power supply to achieve signal and power transmission.

Power adapter/converter

Power adapter/converter

Function: Provide the appropriate operating voltage and current for the sensor.

Since different sensors have different operating voltage requirements, such as the common 3.3V, 5V, 12V, etc., and the actual power supply may not be able to directly meet these requirements, a power adapter or converter is required for voltage conversion and voltage regulation.
