Pyroelectric sensor.

The controller can work with pyroelectric sensors or ultrasonic rangefinders in any combination. Pyroelectric sensors are easy to install and connect, do not require additional settings. They determine the movement of objects, the temperature of which is 10 degrees or more higher than the temperature of the surrounding objects. They can detect movement up to 5 meters away. The angle of view of the sensors is approximately 45-50 degrees (for more details, see the diagram in the user manual). The sensors are not demanding on the choice of installation location and can be installed near the floor or steps. This type of sensor is preferred if your staircase allows it.

Ultrasonic sensor.

An ultrasonic sensor is a rangefinder that measures the distance to an obstacle. Its principle of operation is based on the emission of an ultrasonic signal, which, after being reflected from an obstacle, returns to the sensor. The controller calculates the distance to the obstacle based on the speed of sound and the signal return time. Compares it with the value that you have written into memory and if the measured distance is less - turns on the light. The maximum distance for detecting obstacles is 1.2m (47 "). The principle of operation of ultrasonic sensors has some technological disadvantages:

• - the sound is not reflected from the sound-absorbing surfaces. The sensor will not see soft sound-absorbing objects
• - the speed of sound depends on temperature and atmospheric pressure, therefore, when this parameter is changed, the distance value may slightly change.
• - The angle of propagation of the sound wave is approximately 45-60 degrees (see the diagram in the user manual for more details). Therefore, it is important to choose the right location for the sensor. It should not be located close to the floor or a step, as if it is close to the side surface, the sensor will measure the distance to this surface, and not to an obstacle on the stairs. Therefore, it is recommended to install the sensor at least 50 cm from the floor or step.
• - Ultrasonic rangefinders are high-frequency devices operating at a frequency of more than 400 kHz. Therefore, use shielded wires no longer than 10m (32 feet) to connect them.

 

Shielded wires must be used for all types of sensors. In this case, the shield of the wire should be connected to "GND" of the power supply. This will protect the system from electromagnetic interference and inductive pickup. Since any wire is an antenna, it collects inductive interference from other electrical devices in your home. Failure to comply with this rule can lead to erroneous switching on of the system due to inductive currents in the wires.

The controller is in standby mode. At this time, a standby effect may appear on the stairs. It can be:

• - completely off LEDs.
• - Only the first and last rungs are enabled in low brightness or animated modes.
• - The outermost LEDs on each step on the left and right side are on.
• - Running light on the left and right on the extreme LEDs with a certain interval of time. To indicate the location of the stairs in the dark.

If a turn-on signal is received from one of the two sensors, the controller will start sequentially turning on the LEDs of the steps from the triggered sensor to the opposite side. You can also select any static color and many turn-on effects in runtime. You can also choose dynamic turn-on effects: rainbow effect, flame effect.

After all steps have been turned on, the system will go into standby mode before shutting down. You can set the waiting time yourself. If during this time one of the sensors is triggered, the wait timer will restart. The light will be turned off when the waiting time has elapsed since the last triggering of the sensor. Then the light will turn off in the same direction.

You can activate the use of the light sensor and set the threshold and sensitivity for turning off the system when a certain level of illumination is exceeded. If the room becomes lighter than you indicated, the light will be turned off. However, you can still forcibly turn on the light using the touch buttons on the controller or switches if you are using them. But the sensors will not turn on the light. If the illumination level becomes lower, the controller will turn on standby mode again and start polling the sensors.

Also, when the light sensor is activated, you can adjust the sensitivity of the sensor in order to exclude its reaction to short-term changes in lighting caused, for example, by the headlights of cars passing on the street, and the like.

You can also activate the adaptive brightness mode. In this mode, you set the percentage to decrease the brightness from the one you set in complete darkness. This way the controller will calculate and dim the LEDs as the overall lighting level changes. For example, you set the threshold for turning off the light to 150lm, the brightness for the standby mode is 30, and the brightness for the on mode is 100 points. And they asked to reduce the brightness in the dark by 70%.

Then, in complete darkness, the brightness of the steps will be 9 points in the standby mode, and 30 points in the operating mode. This will keep your eyes in the dark and prevent the light from blinding you. Moreover, as the illumination decreases, the brightness will proportionally change as the illumination in the room decreases. This ensures comfortable observation of the lighting.

The system is configured using the built-in WEB-server through the WEB interface. You can connect to the controller's Wi-Fi hotspot from your mobile device, or configure the system to work on your home network using a router. Then you can connect to the controller from any device on your home network. Having connected to the controller's WEB interface, you can set:

• - Type of LED strip used
• - The number of steps and the number of address pixels for each step.
• - Select the type of sensors used and set the switching distance for ultrasonic sensors.
• - Configure Wi-Fi connection and home network settings
• - Select an effect in standby mode (or disable it)
• - Select the switch-on effect in operation.
• - Adjust color and brightness for standby
• - Adjust the color and brightness for the working mode of inclusion.
• - Set the speed of the effects to turn on and the time to wait before turning off
• - Customize dynamic animated effects, frame rate, number of colors and so on. Depending on the selected effect.
• - Configure the mode of using the light sensor, shutdown threshold, sensitivity and adaptive brightness parameters if you want.
