Log Entry #8 : Sensor/Transmitter Complete !
Log from Remote Water Consumption Display
After quite a bit of development and experimentation, the sensor/transmitter portion of this project is complete. I'm VERY happy to report it has successfully transmitted water consumption data from the meter to my desk. As you can see in the schematic...

Depth Pressure Sensor / Water Dive Depth
Log from Smartwatch 10 Years Ultra-Long Battery Life
Sensor for depth measurements:https://www.te.com/usa-en/product-MS583730BA01-50.htmlhttps://www.digikey.com/en/products/detail/te-connectivity-measurement-specialties/MS583730BA01-50/562950130 bar/300m, 1uA, i2cSeems like a winner, for only $14, will...

First revision of the Sensor Tile
Log from STM32L4 Sensor Tile
06/16/2017I redesigned the Sensor Tile slightly replacing the power switch with a smaller ALPS SSAJ110100 switch, replacing the 3 mm x 3 mm MPU6500 with a 2mm x 2 mm BMA280 accelerometer but otherwise it's still the same concept. The accelerometer change...

A cheap and simple wind direction sensor
Log from Southampton Sailing Robot
For an autonomous sailing boat application the wind direction sensor is a key component because the sail settings as well as the sailing strategy rely on the direction of the wind. We have chosen an affordable, simple and easy to waterproof solution...

Embedded Sensor Fusion: Part 3 The simulation
Log from SunLeaf
IntroductionIn this section we're going to go over the performance of the IMM-KF. Basically this will involve walking through the Matlab code that I used. First I'm going to discus how I constructed the final system. Then I'm going to highlight some...

Embedded Sensor Fusion: Part 1 The models
Log from SunLeaf
IntroductionI wanted to talk a little about how we are going to do manage and estimate the sensor measurements on board the STM32F4 uC. The goal of this algorithm will not only be to give an accurate measurement of the current state of the flora but...

Implementation of 2D LIDAR-Camera Sensor Fusion
Log from Multi-Domain Depth AI Usecases on the Edge
After doing 3D LIDAR-Camera Sensor Fusion, we need to do the mathematical variation for 2D, as the assembled gadget is equipped with 2D RP LIDAR A1 to minimize the cost. 2D LIDAR scans the environment in a 2D plane, orthogonal to the camera plane. The...

Pt.1 Sensor Design and Prototyping
Log from WiFi-Enabled Visual Doorbell
Full video on this subject (this is literally the script): https://www.youtube.com/watch?v=Psy6lRcdGtk Introduction Old houses, like my parents’ home, comes wired with simple electromechanical doorbells. They’re a simple electromagnet with a metal...

[URUS TEST] - Testing URUS Joypad usb example (infrared sensor)
Log from URUS
This is a demo running URUS VR Joypad driver example with infrared sensor on Arduino mega connected via USB to Linux/Debian pc, this should work on any other OSes. Infrared sensor is attached to X axis Analog GPIO input, the "smooth" process is performed...

(edited) Transcript for Environmental Sensor Hack Chat Part 1
Log from Environmental Sensor Hack Chat
Let's get started! -= Wolf =-3:06 PMpollution is definitely an unresolved issue in the copper industry, the amount of unusable bi products is astounding Today in the chat, we have @Radu hosting @Radu Motisan Radu is from Romania, and was a Hackaday Prize...

Using Analog Temp Sensor with LCD on Arduino
Log from Arduino LCD Temperature Controller
Hardware SetupIn this example I hook up the TMP36 sensor to one of the analog input pins on the Arduino Uno and then I tie the 3.3V output supply from the Arduino to the AREF pin using it as an external reference for the ADC to get better accuracy. (When...

mlx90640 sensor reads degrees on Arduino! uses 852 bytes ram.
Log from mlx90640 sensor works w 800 bytes
https://github.com/jamesdanielv/thermal_cam_mlx90640/blob/master/MLX906040_1tempcell.zipthis is a test code setup that reads degrees c on arduino. sketch uses about 20k , and it uses 852 bytes of ram. code is not optimized or shrunk in size yet. it is...

Presence detection using the AMG8831 infrared sensor array
Log from Energy-harvesting sensors for Assisted Living
Via an I²C-capable level shifter based on BSS138 FETs, a test setup was built, with the AMG8831 being connected to an ATMega328 AVR microcontroller. The level shifter was used to allow I²C communication between the AVR (with a logic level of...

The STM8S001J3M3 is finally cheap (a small MODBUS sensor board)
Log from eForth for cheap STM8S gadgets
Edit: there is now a HaD project for the STM8S001J3RS485 breakout!.It's been a while since I last worked with STM8S001J3 chips - ST's contested take on SO8 ATtiny85-like µCs. The STM8S001J3 is a member of the "STM8S Low Density" family but it's...

Added ultrasonic sensor, starting to work on mobile controller
Log from Legged Robot 9 Servos (hexapod type)
Added an ultrasonic sensor to the front, had to use an analog pin as ran out of digital pins. Again it has the issue of needing a near-perfect surface to hit but it is surprisingly very accurate in terms of distance measurement. The program is basic,...
