Introduction :
The seeed studio 24GHz mmWave Sensor is used in this project. It can use UART to send sensor data. But also as per the documentation.
- The human presence status output interface. You can use the level of these two pins to determine the current human movement in the environment. S1 output: high level - occupied, low level - unoccupied. S2 output: high level - active, low level - stationary.
So I am using GPIO read to read the status of the pins and publish on the webserver. I am using webserver example and inserting GPIO read and write functionality.
