So I've done some project logs about my 915MHz Droplet hardware and Hub. They have really been solid pieces of hardware but I'm always looking to improve. There are a few things that I dislike about droplets that are preventing me from proliferating...
DIY SonarFirst lets start with the expected signal level.Based on the 400RT160 datasheet (http://www.robot-electronics.co.uk/files/t400s16.pdf) and the Pro-Wave Electronics Corporations application note (http://www.prowave.com.tw/pdf/an0508309.pdf) the...
Although the work to decode the NASA Wind Sensor was already completed as part of the original pyboard based system, I think that it is of interest and a key part of the project so it is probably worth discussing as one of the key technical challenges...
Important module of the motor is the temperature sensor. I added the sensor so that I can control the temperature of the motor. The sensor measures the temperature and if it's above [X] degrees celsius I need to stop the motor to prevent it from overheating....
I just got an interesting question.Can I use X sensor?The answer depends on three basic properties;1 you need a 1 Bar sensor for best accuracy2 it must operate at 5V and produce a voltage swinging from as low as possible to as close as possible...
Until now we have been using the OV5647 image sensor, the biggest advantage of which was that it could handle up to 90FPS, but we were not satisfied with the image quality. As an alternative, we obtained a small sensor unit with an IMX219 sensor....
My entire project depends on the MAG-3110 sensor being able to detect and measure the field of the magnets buried inside my standard water meter. To test my presumption that it would I had to build a test system. It's really pretty simple. The brain...
I'm going into a second iteration of the project. The first step was a redesign of the XYZ sensor board. These are the major improvements:Increased sensitivityThe sensors felt slow and unresponsive on some of the darker video patterns, particularly those...
Available sensor modulesA recent addition to the available sensors for use in AAL environments are MEMS infrared sensor arrays, which allow contactless temperature measurement of multiple areas at the same time. Sensors with a resolution of up to 8 x...
With my week-in-the-sun over, I decided where I wanted to place the main sensors (after some research and experimentation with a couple of microwave Doppler modules) and made the appropriate holes in the polycarbonate strip that will become the sensor...
The wind vane indicates the direction that the wind is blowing. It is the most complex of the sensors in the Sparkfun Weather Sensor Kit. It has eight reed switches, each connected to a different resistor. As the wind vane rotates, a magnet closes the...
Introduction In the last log, we tried using Capacitive sensing to sense the ball, but that ultimately failed. In this log, we are going to explore an inductive sensing method to detect the ball's position on the plate. Inductive proximity...
I have spent the last year going over possible technologies and methods. My criteria for the gravitational imaging network is Three axes : so that each sensor can determine direction. Each axis of the signal is very precise. Fitting a one...
Color Sensor board with the VEML6040 chip for color detection with built in led for low light situations. This also has mousebites on the sensor part of the board so it can be removed and the color sensor can be mounted closer and in a smaller form factor...
