Sensors

Assigned symbol

For each distinct quantity, there is an?

optically (photoelectric) or by physical process (ionization)

Smoke can be detected either?

Binary number system

The simplest number system.

hypochlorous acid and chlorite is formed

When chlorine is dissolved into water it can appear as a number of different forms when?

Binary number system

a base-2 system because it contains two digits 0 and 1.

Pressure sensor

a device for pressure measurement of gases or liquids.

smoke detector/smoke sensor

a device that senses smoke, typically as an indicator of fire.

Photoelectric sensor

a device used to determine the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver.

Temperature Sensor

a piece of electronic equipment that detects the temperature of its surroundings and transforms the incoming data into electronic output data to control record or signal temperature variations.

Proximity sensor

a sensor able to detect the presence of nearby objects without any physical contact.

Temperature Sensor

allowing us to "sense" or detect any physical change in that temperature, generating an analog or digital output.

Passive Infrared Sensor (PIR sensor)

an electronic sensor that measures infrared (IR) light radiating from objects in its field of view.

Bits

binary digits are also called?

Decimal system

called a base 10- system because it contains ten digits, 0 through 9.

smoke detector/smoke sensor

can be detected either optically (photoelectric) or by physical process (ionization).

Chlorine residual sensor

designed to measure the amount of chlorine in a solution.

Photoelectric sensor

emits a light beam (visible or infrared) from its light-emitting element.

The binary system

it contains only two digits, 0 and 1.

Temperature Sensor

it generates an analog or digital output.

Decimal Numbers

known as Base 10.

Hexadecimal Numbers

known as Base 16.

Binary Numbers

known as Base 2.

Octal Numbers

known as Base 8.

Turbidity sensor

measures the amount of dissolved or suspended particles in a given solution.

Number system

nothing more than a code.

Ultrasonic sensor HC-SR04 (Ultrasonic sensor)

offers excellent non-contact range detection with high accuracy and stable readings in an easy-touse package from 2cm to 400 cm or 1" to 13 feet.

Proximity sensor

often emits an electromagnetic field or a beam of electromagnetic radiation, and looks for changes in the field or return signal.

pH sensor

one of the most important tools for measuring pH and is commonly used in water quality monitoring.

Veitch diagram

provides a fast and easy method for reducing a complicated expression to its simplest form.

Temperature Sensors

quantify the quantity of heat energy or even coldness produced by an item or system.

Binary data

represented by binary digits, called bits.

Turbidity

the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air.

Free Chlorine

this referred to as _______________ which when measured as part of chlorine demand forms our Residual Chlorine.

pH sensor

this type of sensor is capable of measuring alkalinity and acidity in water and other solutions.

The binary system

used in digital and microprocessor circuits because of its simplicity.

Ultrasonic sensor HC-SR04 (Ultrasonic sensor)

uses sonar to determine distance to an object.

Pressure sensor

usually acts as a transducer; it generates a signal as a function of the pressure imposed.

chlorine

when it is dissolved into water it can appear as a number of different forms when hypochlorous acid and chlorite is formed.
