Capacitive soil moisture
Log from Keep the basil alive
Ok i wanted to use the Chirp as a soil moisture sensor but they are out of stock :(Than I started thinking, why spend extra money on a seperate sensor? The teensy LC has some very capable capacitive measuring pins on its own.So from some left over PCB...

Mislabeled sensor!
Log from Stratasys Dimension SST
January 23, 2016: Since the service manual was telling me that my error code meant the X-axis end of travel sensor was incorrectly being triggered, I found the sensor labeled "end of travel" and bypassed its wiring harness. I used a brand new sensor....

Sensor Testing
Log from Wall Following and Obstacle Avoidance
Sensor Accuracy TestI performed a test of sensor accuracy and precision. The test placed the sensor on the stationary robot. A reference object, a large flat object, was placed in front of the sensor and slowly moved away from the sensor at a nearly...

Gyro Sensor
Log from Arduino gaming console
One of the main components I have used in this project is the MPU6050 gyro sensor. The gyro sensor has brought in a physical aspect to my game which now requires the player to rotate the console sideways in order to move their character horizontally....

Sensor Design
Log from Seismometer
Please forgive me. It's been nearly 4 years since I worked on this problem. A lot of the details have probably been forgotten in the interval. There is a lot of ground to cover, so this might be a very long log entry. Initially I thought that the way...

Gas sensor
Log from Enhancer mask
I use the MiCS5524 gas sensor, mainly because it is sensitive to carbon monoxide. Carbon monoxide is a highly toxic, colorless, odorless, and tasteless gas. The gas sensor can also detect other gases, but except for hydrogen, our sense of smell can detect...

Gas sensor
Log from Enhancer mask lite
I plan to use the MiCS5524 gas sensor, mainly because it is sensitive to carbon monoxide. Carbon monoxide is a highly toxic, colorless, odorless, and tasteless gas. The gas sensor can also detect other gases, but except for hydrogen, our sense of smell...

Sensor Testing
Log from 3D Magnetic Field Scanner
Maxwell CoilI've decided to use a Maxwell coil to calibrate the sensor(s) on the scanner. Early experiments have shown that the datasheet scale values are rough estimates of the true sensor scales, and calibration will be necessary to obtain acceptable...

EC Sensor
Log from UltraTower
EC is the abbreviation for Electro Conductivity. It is used to determine the nutrient concentration of the solution. This factor is essential to optimize the soilless culture. Indeed, the nutrient concentration will not be the same for a seeding as for...

pH Sensor
Log from UltraTower
pH is important in hydroponic systems, indeed depending on pH of the solution certain minerals will be more or less accessible for the plants. This is why monitoring pH is essential to optimize plant production. The ideal range is between 5.5 and 6.5...

Sensor Smoothing
Log from Color Compass
Let's talk about how the program works to gather the heading information for later use to generate colors.First off, the hard part was already taken care of by the kind people at Adafruit. The compass I used was their LSM303 breakout board. This device...

Minimum sensor
Log from Discrete component object recognition
Goal The goal of this task was to evaluate how simple a sensor array would be needed to reach object recognition on the MNIST database to a commercial level accuracy. According to this site, commercial OCR systems have an accuracy of 75% or higher on...

Quirky sensor data
Log from Aquametric - Cellular based stage monitors
Recently, we visited the sensor and did some in-field fixes to the thermistor. The temperature now seems to be sending back sensible readings now and we can see the day night cycle in the stream temperature pretty well. Our conductivity sensor, on the...
