RE200B is a highly efficient, low power, passive infrared (PIR) sensor module that is widely used in various applications including security systems, energy-saving devices, and home automation. This module is designed to detect human presence by sensing infrared radiation emitted by the human body.

The RE200B PIR sensor module operates on the principle of thermal detection. When a human enters the detection range, the sensor detects the changes in infrared radiation levels and triggers an output signal. This output signal can be used to activate alarms, turn on lights or appliances, and initiate other actions in response to human presence.

One of the key features of the RE200B module is its low power consumption. This makes it ideal for battery-operated devices such as wireless security systems and motion-activated lights. The low power consumption also contributes to its efficiency, ensuring that it can operate for extended periods without draining the power source.

Another notable feature of the RE200B sensor module is its compact size and ease of integration. The module measures just a few centimeters in length and width, making it suitable for installation in various devices without taking up much space. Additionally, it has a simple interface that allows for easy connection to microcontrollers or other control devices.

In terms of detection capabilities, the RE200B offers a wide field of view and a long detection range. With a field of view of up to 110 degrees, it can cover a significant area, making it suitable for large spaces like living rooms or hallways. The detection range can be adjusted, typically from 3 to 7 meters, allowing for customization based on specific requirements.

The RE200B PIR sensor module is also designed to be highly sensitive and reliable. It can detect the smallest changes in infrared radiation, ensuring accurate and prompt detection of human presence. The module is equipped with advanced signal processing algorithms and filtering mechanisms to eliminate false triggers caused by non-human sources such as pets or moving objects.

Furthermore, the RE200B module can be easily customized to meet specific use cases. It allows for adjustments such as sensitivity and time delay, enabling users to fine-tune the sensor's behavior according to their needs. This flexibility makes it suitable for a wide range of applications, from simple motion-activated lighting to complex security systems.

In conclusion, the RE200B PIR sensor module is a versatile and reliable device that plays a crucial role in various applications requiring human presence detection. Its low power consumption, compact size, wide field of view, and customizable features make it a popular choice among designers and developers. With its ability to accurately detect human presence, the RE200B contributes to the efficiency, convenience, and security of numerous devices and systems.
