Overview
This product is a relay module with reserved interfaces for a human detection sensor/MCU. It is mainly designed to help users combine the Human Sensor Module LD2410 with the relay, but it can also be used with other sensors or MCUs. The onboard AC-DC power module can directly connect to a 100-240V AC voltage and convert it to 5V DC, providing power to sensors or other MCU modules. When users are not using AC power, they can also supply the module with DC 5V. This product can be applied to smart environments such as household appliances and industrial equipment control.
