I. TI Humidity Sensors

TI humidity sensors utilise capacitive sensing technology at their core, specialising in high-precision, low-drift and contamination-resistant environmental humidity detection. Furthermore, most products integrate temperature sensing capabilities, enabling integrated temperature and humidity monitoring. They are perfectly suited to demanding industrial and automotive applications, addressing the pain points of traditional humidity sensors, such as drift, susceptibility to VOC interference and high power consumption.

1. Operating Principle

Utilising a polymer capacitive sensing structure, changes in ambient air humidity alter the dielectric constant of the polymer dielectric, thereby causing a linear change in the sensor’s capacitance. Through an internal high-precision signal conditioning circuit, these capacitance changes are converted into standard digital or analogue electrical signals. Additionally, a built-in temperature compensation algorithm eliminates the impact of temperature on humidity measurement accuracy.

2. Core Products and Technical Advantages

TI’s mainstream humidity sensor range encompasses a full series of consumer-grade, industrial-grade and automotive-grade products, with representative models including the HDC2010 and HDC3120-Q1.

II. TI Optical Sensors

TI optical sensors focus on optical signal detection and ambient light sensing, covering categories such as ambient light sensing, proximity sensing and spectral detection. They are characterised by low noise, high linearity and precise light intensity recognition, enabling the accurate capture of faint light signals and making them suitable for photoelectric sensing applications in various smart devices.

1. Operating Principle

Based on the photoelectric conversion effect, these sensors utilise photodiodes to convert light signals—such as ambient light and reflected light—into faint electrical current signals. Through internal gain amplification, noise reduction and analogue-to-digital conversion circuits, they output standardised light intensity values. Certain products incorporating integrated infrared emitter modules can achieve reflective proximity detection.

III. TI Magnetic Sensors

TI’s magnetic sensors, based on the Hall effect and magnetoresistive sensing technologies, comprise a comprehensive product portfolio including Hall switches, latches, single- and multi-axis linear magnetic sensors, and angle sensors. Specialising in position detection, rotational speed monitoring, current sensing and angle measurement, they serve as core sensor components for motion control in industrial and automotive applications.

1. Operating Principles

These are divided into two main technical approaches: Hall sensing and magnetoresistive sensing. Hall sensors utilise the Hall effect, whereby changes in the magnetic field generate a transverse induced voltage to detect magnetic field strength; linear magnetoresistive sensors utilise changes in the resistance of a magnetoresistive element caused by the magnetic field to precisely output an electrical signal proportional to the magnetic field strength. Multi-axis products enable three-dimensional magnetic field detection and angle calculation.

Utilising high-frequency millimetre-wave technology at 77 GHz and 60 GHz, they enable non-contact distance and speed measurement, detection of subtle human movements, and trajectory tracking. Compared to infrared and ultrasonic sensors, they offer the advantages of all-weather operation, resistance to environmental interference and higher accuracy, making them essential hardware for autonomous driving, smart security and smart home applications.

1. Operating Principle

By emitting high-frequency millimetre-wave electromagnetic waves, the sensor detects the waves reflected from target objects. Utilising Frequency-Modulated Continuous Wave (FMCW) technology, it precisely calculates the target’s distance, velocity, angle and movement trajectory based on the frequency and phase differences between the transmitted and received signals. This enables the detection of subtle movements, such as slight body movements and object displacement.
