# 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](https://github.com/Aircoookie/WLED/wiki/Control-a-relay-with-WLED) 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](http://www.esp8266learning.com/wemos-mini-pir-sensor-example.php) 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
|
|
|
|
1. Copy the file `usermod_PIR_sensor_switch.h` to the `wled00` directory.
|
|
2. Register the usermod by adding `#include "usermod_PIR_sensor_switch.h"` in the top and `registerUsermod(new PIRsensorSwitch());` in the bottom of `usermods_list.cpp`.
|
|
|
|
Example **usermods_list.cpp**:
|
|
|
|
```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:
|
|
|
|
1. Include `usermod_PIR_sensor_switch.h` **before** you include the other usermod in `usermods_list.cpp'
|
|
|
|
or
|
|
|
|
2. Use `#include "usermod_PIR_sensor_switch.h"` at the top of the `usermod.h` where you need it.
|
|
|
|
**Example usermod.h :**
|
|
```cpp
|
|
#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
|
|
}
|
|
//...
|
|
};
|
|
```
