### HCSR501
A boolean value of the PIR sensors state is sent when a state change occurs. The length of time that the PIR stays in a triggered state depends on the PIR hardware and is not changed by OpenMQTTGateway.
`home/OpenMQTTGateway/HCSR501toMQTT {"hcsr501":"false"}`
You can have another PIN mirror the value of the PIR sensor output by adding the following to config_HCSR501.h
This can be useful if you would like to connect an LED to turn on when motion is detected.
`#define HCSR501_LED_NOTIFY_GPIO 4`
