Magic Mote MSP430G2553 wireless sensor node with NRF24L01+ module

This is my first time designing a PCB for MSP430. I really like the NRF24L01+ booster pack but I would like something smaller to use for remote temperature sensors. With that in mind I've designed a 24.5 x 50 mm PCB (2 on a 5x5 cm prototype) featuring MSP430G2553 and an adapter for a 8-pin NRF24L01+ module using essentially the same pinout, with the intention of using the Spirilis library. There's a jack so ...

Multi-Sensor Data Plotting using Arduino IDE

Monitoring of various process variables such as temperature, pressure, viscosity, humidity, pH and flow-rate is very important in steel plants, petrochemical and other such industries. The human-machine interface (HMI) at the operator station displays a continuous and real-time trending of process variables on a monitor for viewing by the control room personnel. This project describes the method of monitori ...

Control Pi-Plate With Spark Core

The ppDAQC board from Pi-Plates.com is an inexpensive yet powerful solution for expanding the input/output capabilities of the Spark Core. And since Pi-Plates are stackable, it is a simple task to scale up the I/O capabilities of a single Core. All that is required for connectivity are the four SPI signals (signals A2-A5) as well as a single digital output (D6). Power can come from the Core or from the ppDA ...

GPS Clock using Arduino

Global positioning system (GPS) synchronised clocks give accurate time. These clocks are universal and commonly used at railway stations, bus stands and airports. These are widely used for military purposes too. Here we describe a GPS clock based on Arduino Uno R3—an AVR ATmega328-based microcontroller board with six analogue inputs pins and 14 digital input/output (I/O) pins. The microcontroller has 32kB I ...
