Line voltage occupancy sensor is a cutting-edge technology that has gained significant attention in the smart home and building automation sectors. This sensor is designed to detect the presence or absence of a person in a room or space by measuring the line voltage. With the rapid development of the smart home industry, line voltage occupancy sensors have become an essential component for energy efficiency and convenience. In this article, we will explore the working principle, applications, advantages, and future trends of line voltage occupancy sensors.

Introduction to Line Voltage Occupancy Sensor

Line voltage occupancy sensor, also known as line voltage sensor or voltage sensor, is a device that utilizes the line voltage to detect the presence of a person in a certain area. The sensor is typically installed in rooms, corridors, or other spaces where energy-saving and automated control are required. By measuring the line voltage, the sensor can detect changes in the electrical current caused by the presence of a person and trigger corresponding actions, such as turning on or off lights, heating, or air conditioning systems.

Working Principle of Line Voltage Occupancy Sensor

The working principle of line voltage occupancy sensor is based on the detection of the change in line voltage caused by the presence of a person. When a person enters a space, the resistance in the human body will affect the line voltage, resulting in a change in the electrical current. The line voltage occupancy sensor can detect this change and trigger the corresponding control circuit to perform actions such as turning on or off lights. The typical working process of line voltage occupancy sensor is as follows: 1. The sensor detects the line voltage and converts it into an analog signal. 2. The analog signal is then processed by the sensor's internal circuitry to determine whether the line voltage has changed. 3. If the line voltage has changed, the sensor triggers the control circuit to perform the desired action, such as turning on or off lights. 4. The control circuit then sends a signal to the electrical appliance to turn it on or off.

Applications of Line Voltage Occupancy Sensor
