Embedded Modbus infrared human body sensor: high stability, easy installation, wide applicability

EmbeddedModbus Infrared Human BodySensor, featuring high stability, easy installation, and wide applicability. It is manufactured using SMT technology, with stable performance and high cost-effectiveness.Product Features

• High Stability: Using PIR intelligent sensors, it has good stability and anti-interference ability.
• Easy to install: The installation diameter is only 42mm, which is more beautiful, compact and practical.
• has a wide range of applications: widely used in smart homes, hotels, and indoor public places.

Main function

• Human body sensing: detects whether there is a moving object and outputs a 485 signal.
• ID setting: ID setting data can be sent through the 485 serial port for easy differentiation of multiple sensors.
• LED indicator light: optional on or off, convenient for on-site installation and debugging.
