Sense and Sound with PIR sensor. Download your own speech, music or sound effects. The PIR motion sensors have a unique download function for MP3 files. You can then easily transfer your MP3 sound files directly to the Sense and Sound's internal memory. This is done via the USB connection. Your MP3 file will be played automatically after the PIR sensor is activated. Easy to use, and step-by-step instructions are also included.
APPLICATIONS for the Sense and Sound with PIR sensor:
Make an audible warning for a restricted area (for example, "use the side entrance")
Audible reminders to help people with dementia or memory problems (for example, "don't forget to close the door")
Audible security alarms (for example, "beware of the step")
Make a special greeting at the doorway (so that someone is welcomed, for example)
Get the attention and impress by adding a speech, music or sound effects (for example in presentations)
Upload MP3 sound files with speech, music or other sound effect
Update and change your messages as often as you want
Automatic audio playback after the PIR sensor is activated
High-quality MP3 sound reproduction
Unit saves multiple MP3 files to enable loop playback
Two playback settings: both single track and multiple tracks
In Multiple tracks mode, one track is played after each activation (in order of file name)
Also two volume settings: Low and High
Also includes an optional wall mounting bracket
Audio playback format: MP3 format only
Sensor activation distance: up to 4 meters with a 120 degree angle
Volume level: up to 90 dB (depending on the original recording)
Dimensions: 90 x 60 x 25 mm
Internal memory: 4 MB
Micro USB connection for supporting a 5-volt DC power adapter
Recording time: approximately 4 minutes, (calculated from 128 Kbps MONO-bit speed)
Battery life: 24 hours, ie 1,440 minutes, (86,400 seconds) Number of views: Based on the above calculations for the battery life, a 10-second message is played 8,640 times.
Two power options: 3 x AAA batteries or AC adapter (however, batteries are installed by Memory Aid)
What is PIR?
PIR stands for Passive Infrared. A PIR sensor is an electronic sensor that measures infrared light emitted by objects in its field of vision. All objects with a temperature above zero emit heat energy in the form of radiation. Usually this radiation is invisible to the human eye because it emits radiation at infrared wavelengths. But it can be detected by PIR sensors. PIR sensors do not detect or measure heat, but instead detect the infrared radiation emitted by an object. A PIR-based motion detector is used to detect movement of people, animals or other objects. They are more often used in burglar alarms and automatically activated lighting systems.
What is the difference between normal motion sensors and PIR sensors? PIR sensors do not detect movement, but detect abrupt temperature changes at a certain point using the infrared radiation level. If an object, such as a human, passes in front of the background, such as a wall, the temperature at that point will rise from room temperature to body temperature and then back again. This rapid change therefore activates the detection.
Playback calculations based on 4 MB of memory A playback time of 8 minutes can be achieved with an MP3 file with a bit rate of 64 Kbps. A playback time of 4 minutes can be achieved with an MP3 file with a bit rate of 128 Kbps. A playback time of 2 minutes can be achieved with an MP3 file with a bitrate value of 256 Kbps.
