Window detector circuit diagram

It employs two comparators to detect over-voltage or under-voltage condition. This circuit utilizes two comparators in parallel to determine if a signal is between two reference voltages. If the signal is within the window, the output is low thus RELAY is in off condition and also LED is off.

What is a window comparator circuit?

A Window-Comparator is a circuit configuration, usually consisting of a pair of voltage comparators (inverting and non-inverting), in which the output indicates whether an input signal is within the voltage range bounded by two different thresholds.

How does comparator circuit work?

A comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side) or a 0 (the voltage at the negative side) to indicate which is larger. Comparators are often used, for example, to check whether an input has reached some predetermined value.

What is the difference between op-amp and comparator?

Unlike operational amplifiers that usually operate with the input voltages at the same level, comparators typically see large differential voltage swings at their inputs. But some comparators without rail-to-rail inputs are specified to have a limited common mode input voltage range.

What are the type of window detectors?

In general, there are three main types of window sensors—contact sensors, glass break sensors, and motion sensors—although there are variations within those three categories.

What is the function of a detector circuit?

In radio, a detector is a device or circuit that extracts information from a modulated radio frequency current or voltage.

What is the purpose of the comparator?

A comparator is used to compare a measurable quantity with a reference or standard such as two voltages or currents. It outputs a digital signal showing the results.

Where are comparator circuits used?

Generally, comparators are used in the devices such as relaxation oscillators, analog to digital converters (ADCs), and also in the devices that are used to measure analog signals. The comparators consist of high-gain differential amplifiers and we can use an op-amp as a comparator circuit.

What is UTP and LTP in window comparator?

One called the Lower Upper Trip Point (UTP) and the other being called the Lower Trip Point (LTP). The difference between these two trip points is called Hysteresis. The amount of hysteresis is determined by the feedback fraction, β of the output voltage fed back to the non-inverting input.

What are the two types of op-amp?

There are two types of op-amps: single power supply type and dual power supply type. In the case of a single-supply op-amp, VCC is positive with respect to GND. In the case of a dual-supply op-amp, VCC is positive and VEE is negative with respect to GND.

Why is it called op-amp?

An operational amplifier (op-amp) is an integrated circuit (IC) that amplifies the difference in voltage between two inputs. It is so named because it can be configured to perform arithmetic operations.

How many op amps do you need for a window comparator?

Op-amp window comparators are a type of voltage comparator circuit which uses two op-amp comparators to produce a two-state output that indicates whether or not the input voltage is within a particular range or window of values by using two reference voltages.

How many window types are there?

There are 7 main types of windows for your home: Single-Hung Windows. Double-Hung Windows. Awning Windows. Horizontal Sliding Windows.

Do I need a sensor on every window?

No, you don't need a window sensor on every window. You'll want to put them on ground-floor windows and those that you believe an intruder could access. You should also put them on any windows you want to monitor in case someone inside the house (like an adventurous teen) tries to slip out.

What is a window safety device?

Simply put, a window safety device can be permanent or removable, and it attaches to the window itself to prevent the window opening past a certain distance. In Sydney, it's now mandatory that all strata buildings get fitted with window safety devices that restrict the window's ability to open past 12.5cm.

What is the principle of detector?

When radiation passes inside a detector, it causes ionization of gas atoms, separating atoms into positive ions and electrons. Separated electrons and positive ions are attracted to the electrodes, causing a current to flow. This is converted into electric signals, which are then measured as the amount of radiation.

Why do we need a detector?

Obviously the aim of a detector is to capture diffracted photons in an experiment and to rapidly transmit that information as a suitable signal to the observer/computer with as little time/space distortion as possible.

What is a detector switch?

Detector Switches are used to “detect” internal mechanical movements and convert human manual operations, such as the opening of a door , to electronic signals. Panasonic Detector Switches use a mechanical sliding spring design to ensure consistent signal output.

What are the types of comparator?

Types of Comparators: Mechanical comparators 2. Optical comparators 3. Electrical & Electronic comparators 4. Pneumatic comparators 5.

What are the advantages of comparator?

Advantages of Electrical Comparator: Vibrations are reduced due to least weight of mechanical. It consists of less moving parts. By AC supply the friction errors are reduced. For measuring units the indicating instrument can be held at remote locations.
