PIR sensor switch
This usermod-v2 modification allows the connection of a PIR sensor to switch on the LED strip when motion is detected. The switch-off occurs ten minutes after no more motion is detected.
Story:
I use the PIR Sensor to automatically turn on the WLED analog clock in my home office room when I am there. The LED strip is switched using a relay to keep the power consumption low when it is switched off.
Webinterface
The info page in the web interface shows the items below
- the remaining time of the off timer. I recommend to deactivate the sensor before an OTA update and activate it again afterwards.
Sensor connection
My setup uses an HC-SR501 sensor, a HC-SR505 should also work.
The usermod uses GPIO13 (D1 mini pin D7) by default for the sensor signal but can be changed in the Usermod settings page. This example page describes how to connect the sensor.
Use the potentiometers on the sensor to set the time-delay to the minimum and the sensitivity to about half, or slightly above.
Usermod installation
- Copy the file
usermod_PIR_sensor_switch.h
to thewled00
directory. - Register the usermod by adding
#include "usermod_PIR_sensor_switch.h"
in the top andregisterUsermod(new PIRsensorSwitch());
in the bottom ofusermods_list.cpp
.
Example usermods_list.cpp:
#include "wled.h"
/*
* Register your v2 usermods here!
* (for v1 usermods using just usermod.cpp, you can ignore this file)
*/
/*
* Add/uncomment your usermod filename here (and once more below)
* || || ||
* \/ \/ \/
*/
//#include "usermod_v2_example.h"
//#include "usermod_temperature.h"
//#include "usermod_v2_empty.h"
#include "usermod_PIR_sensor_switch.h"
void registerUsermods()
{
/*
* Add your usermod class name here
* || || ||
* \/ \/ \/
*/
//usermods.add(new MyExampleUsermod());
//usermods.add(new UsermodTemperature());
//usermods.add(new UsermodRenameMe());
usermods.add(new PIRsensorSwitch());
}
API to enable/disable the PIR sensor from outside. For example from another usermod.
To query or change the PIR sensor state the methods bool PIRsensorEnabled()
and void EnablePIRsensor(bool enable)
are available.
There are two options to get access to the usermod instance:
- Include
usermod_PIR_sensor_switch.h
before you include the other usermod in `usermods_list.cpp'
or
- Use
#include "usermod_PIR_sensor_switch.h"
at the top of theusermod.h
where you need it.
Example usermod.h :
#include "wled.h"
#include "usermod_PIR_sensor_switch.h"
class MyUsermod : public Usermod {
//...
void togglePIRSensor() {
#ifdef USERMOD_PIR_SENSOR_SWITCH
PIRsensorSwitch *PIRsensor = (PIRsensorSwitch::*) usermods.lookup(USERMOD_ID_PIRSWITCH);
if (PIRsensor != nullptr) {
PIRsensor->EnablePIRsensor(!PIRsensor->PIRsensorEnabled());
}
#endif
}
//...
};
