CQRobot Ocean Microwave Motion Sensor The CQRobot Ocean Microwave Motion Sensor is a versatile and reliable sensor that is compatible with Raspberry Pi and Arduino boards. It is primarily designed for use in industrial, measurement, and automatic applications. One of the main advantages of this sensor is its ability to amplify a tiny signal received by the microwave sensor and convert it into a square signal with a digital output of either 0 or 1. This makes it easy to integrate with microcontrollers such as Arduino, allowing for easy data processing and handling. The sensor also features a potentiometer on the back that allows users to adjust the sensitivity. This can be useful in situations where the detection light remains on continuously. By turning the potentiometer clockwise, users can decrease the sensitivity and potentially resolve this issue. However, it is important to note that the CQRobot Ocean Microwave Motion Sensor has some limitations. Firstly, it operates on a maximum voltage of 5V, which means it cannot be used with a 24V power supply. Additionally, the output of the sensor is not suitable for directly powering an LED light bar, requiring the use of a relay. Another drawback is that the sensor cannot disable visible light. For users looking for a sensor that does not emit visible light, this may limit its applicability. Finally, it is worth noting that the CQRobot Ocean Microwave Motion Sensor is specifically designed for detecting relatively moving objects. It may not be suitable for detecting the presence of still objects within its range. Overall, the CQRobot Ocean Microwave Motion Sensor offers a reliable and versatile solution for motion detection in various applications. Its compatibility with Raspberry Pi and Arduino boards makes it easy to integrate into existing projects. However, potential buyers should be aware of the sensor's limitations, such as its voltage requirements and inability to disable visible light.
