I haven't gotten the Keyword Spotting working yet, but since today is the deadline I thought I should summarize how far I've gotten. ADC TimingThe impulse that I'm trying to use was sampled at 16KHz with 1 second windows.The equation for samplin...
Continuing on the theme of my previous blog post Light up Coaster using sound sensor , this version of the Light up coaster includes a touch sensor based on the MPR121 capacitive touch, and 3D printed conductive pads all around the coaster which can...
The Cat Detector system was placed outside overnight and the following video illustrates the results obtained. players.brightcove.net/.../index.html Sadly, no cats were actually detected but I feel very confident that should a cat pass by w...
When a device is to be deployed on the field and it will be unattended, it is useful the get some status data from it to determine its operating conditions. In this case, a GNSS receiver is put into an enclosure and installed in a mast on top of a b...
Capturing the audio data from the microphone
The first thing that I need to verify is that I can successfully capture audio data from the microphone to use for keyword spotting using the impulse that was generated previously.
The Wio Terminal uses a...
The world is facing a great pandemic i.e COVID19 virus. Doctors are struggling with the virus though the spread can't be controlled. Also many countries have relaxed the lockdown to some extent. Now, Let's consider the scenario of a public place li...
Software Development Environment
There are a few software development choices supported by Seeed: the Arduino IDE and a couple of MicroPython variants - Adafruit CircuitPython and Seeed ArduPy. I've been using a different MicroPython variant, ...
I have tried to detect cats in my garden previously (CatDogFoxBot #6 : Trying out an Artificial Neural Network ) without much success so I was quite excited to discover that I had accidentally created a cat detector yesterday. I am part way thr...
My task was to measure water surface temperature and at 16 equal points directly below the surface to a depth of 4mm, and the air just above.
I could not just use one sensor and move it up and down because it would mix the fluid and change th...
