A thermopile converts infrared radiation into electrical energy using multiple thermocouples, ideal for temperature sensing, HVAC, and energy harvesting. Key factors include sensitivity, response time, and temperature range.

Hall Effect sensors detect magnetic fields and convert them to electrical signals. They’re used in automotive, industrial, and consumer electronics, with key features like sensitivity, accuracy, and temperature range.

An HDMI modulator converts HDMI signals into RF for distribution via coaxial cables, connecting modern devices to older TVs. It’s used in multi-room setups, with types like HD, 4K, and single/multi-channel options. Key factors include resolution, power, and installation.

Solenoids convert electrical energy into mechanical motion using a magnetic field. Types include linear, rotary, and proportional solenoids, used in applications like valves, locks, and automation. Key factors include design, power, and maintenance.

Avalanche Photodiodes (APDs) are sensitive light detectors used in LiDAR and fiber-optics. They amplify weak signals and are chosen based on wavelength, gain, and noise.

Introduction A hygrometer is a type of instrument used for measuring the amount of moisture or water vapor in the air. It is commonly expressed as a percentage of relative humidity.  Monitoring humidity is important for maintaining comfort, health, and preserving materials and equipment in many environments. Here are more reasons to monitor humidity.  Hygrometers […]

An Inrush Current Limiter (ICL) suppresses the surge of current when devices are powered on, preventing damage. It works by initially providing high resistance and then transitioning to low resistance. Common types include NTC thermistors (passive) and soft starters (active).

Resistance wire, made from alloys like Nichrome and Kanthal, converts electricity to heat. Used in heating elements, resistors, and industrial, household, and medical devices due to high resistivity, stability, and durability.
