MMM-NearCompliments

This is an extension for the MagicMirror. It uses the USER_PRESENCE notification of MMM-PIR-Sensor to activate distance measurement of a HC-SR04 sensor to display the compliments module for a specified time when a measured distance is fallen below a specified distance. Inspired by https://github.com/thobach/MMM-Gestures and https://github.com/mochman/MMM-Swipe.

Installation

1. Navigate into your MagicMirror's modules folder and execute git clone https://github.com/semox/MMM-NearCompliments.git. A new folder will appear navigate into it.
2. Execute npm install to install the node dependencies.
3. Configure config/config.js with documentation below.
4. Reboot your Pi.

Using the module

To use this module, add it to the modules array in the config/config.js file:

modules: [
	{
		module: 'MMM-NearCompliments',
		// position: 'bottom_left',
		config: {
			// See 'Configuration options' for more information.
		}
	}
]

Configuration Options

The following properties can be configured:

Option	Description
echoPin	The echo pin your HC-SR04 is connected to.
triggerPin	The trigger pin your HC-SR04 is connected to.
distance	Specified distance in cm which measured distance has to be smaller to display compliments module. Possible values: int Default value: 70
sensorTimeout	Sensor timeout to ignore bad measurements. Possible values: int Default value: 5000
animationSpeed	Animation speed in ms to display compliments module. Possible values: int Default value: 200
measuringInterval	Measuring interval of two measured distances. Defined in ms. Possible values: int Default value: 500
delay	Delay defined in seconds to show compliments module. Possible values: int Default value: 30
autoStart	Auto start the distance measurment. Use only if MMM-PIR-Sensor is _not_ available. Possible values: boolean Default value: true
usePIR	Should we use PIR sensor to activate only distance measurment when USER_PRESENCE notification is sent by MMM-PIR-Sensor? Possible values: boolean Default value: false
powerSavingDelay	Power saving delay in seconds defined in MMM-PIR-Sensor. It gets overwritten by MMM-PIR-Sensore module and is only defined for backup purpose. Possible values: int Default value: 30
verbose	Verbose mode to give more information in log. Possible values: boolean Default value: false
calibrate	Calibration mode to display measured distance on magic mirror. Note: You have to define position: 'bottom_left' in config.js. Possible values: boolean Default value: false
