(Previously, the height of the two Wi-Fi blocks was smaller than the height of the Bluetooth blocks.) Fixed formatting of the "elaboration information" in the Xtensa LX6 microprocessor block. Added descriptive text to diagram's title for conveying what the ESP32 is (it's a Wi-Fi & Bluetooth microcontroller) for clarity.
ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth.The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, an Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise ...
Hydrostatic pressure level sensors are submersible or externally mounted pressure sensors suitable for measuring the level of corrosive liquids in deep tanks or water in reservoirs. Typically, fluid level is determined by the pressure at the bottom of the fluid containment (tank or reservoir); the pressure at the bottom, adjusted for the ...
A water detector is an electronic device that is designed to detect the presence of water for purposes such as to provide an alert in time to allow the prevention of water leakage. A common design is a small cable or device that lies flat on a floor and relies on the electrical conductivity of water to decrease the resistance across two contacts.
Capacitive sensors can also replace mechanical buttons. A capacitive touchscreen typically consists of a capacitive touch sensor along with at least two complementary metal–oxide–semiconductor integrated circuit (IC) chips, an application-specific integrated circuit (ASIC) controller and a digital signal processor (DSP).
An optical sensor can measure the changes from one or several light beams. When a change occurs, the light sensor operates as a photoelectric trigger and therefore either increases or decreases the electrical output. An optical switch enables signals in optical fibers or integrated optical circuits to be switched selectively between circuits ...
Hall sensors are used for proximity sensing, positioning, speed detection, and current sensing applications [1] and are common in industrial and consumer applications. Hundreds of millions of Hall sensor integrated circuits (ICs) are sold each year [2] by about 50 manufacturers, with the global market around a billion dollars. [3]
Where level must be sensed inside a pressurized vessel, often a magnet is used to couple the motion of the float to a switch located outside the pressurized volume. In some cases, a rod through a stuffing box can be used to operate a switch, but this creates high drag and has a potential for leakage. Successful float switch installations ...
