Product type
Motion sensors are electronic devices that detect and respond to movement in a given environment. They typically work by using various technologies such as infrared, ultrasonic, or microwave to sense motion. These sensors are often made from materials like plastic and metal, housing the electronic components necessary for their operation. Motion sensors are widely used in security systems, automation, and energy management applications.
| Detection range | Up to 30 meters |
| Power supply | Battery-operated or hardwired |
| Output type | Digital or analog signals |
| Operating temperature | -20°C to 50°C |
| Response time | Less than 1 second |
When selecting a motion sensor, consider the detection range and the type of output signal required for your application. It is also important to specify the operating environment, as some sensors are better suited for indoor use while others can withstand outdoor conditions. Additionally, inquire about power supply options, such as battery or hardwired solutions, and ensure the sensor meets any necessary certifications for safety and performance.
