OpenPressure combines an ADS1220 24-bit ADC and a SAMD21 microcontroller to make a complete 24-bit, high precision pressure and temperature sensor interface.
Indoor/Outdoor Positioning System based on Decawave's DWM1000 Ultra Wide Band transceivers.
Just a rather very average indoor positioning system.
An Arduino library for creating custom BLE peripherals with Nordic Semiconductor's nRF8001 or nR51822.
Kalman filtering, also known as linear quadratic estimation (LQE), is an algorithm that uses a series of measurements observed over time, containing statistical noise and other inaccuracies, and produces estimates of unknown variables that tend to be more accurate than those based on a single measurement alone, by estimating a joint probability distribution over the variables for each timeframe. The filter is named after Rudolf E. Kálmán, one of the primary developers of its theory.
A simple library for controlling the AD5933 impedance converter system with an Arduino compatible device.
Arduino driver and library to use Decawave's DW1000 IC and relative modules.
A library that offers functionality to use Decawave's DW1000 chips/modules with Arduino.
