Here I am using my first PIC development board (Pic32mx460F512L) and use an LCD display.

Weather station:

In this application I am playing with basic sensors (analog temperature and digital atm pressure) and trying to create a wireless data transmission.

T°C

N measures: 1point each 5mins for ~5hours.

Principle: the RF communication is taking place between two XBEE tranceivers, the application is based on a microcontroller using two sensors.

Internal modules:

  •    10bits ADC to sense temperature (TMP35),

  •    SPI with the atm pressure sensor (MPL115a1),

  •    UART communication with the XBEE module

 

This is a test of a RF communication between two XBEE modules: one on my laptop is programmed to send a specific command to request data, the other one sends temperature and pressure when it is requested thanks to a UART communication between the microcontroller & the XBEE module.

Here is an example of 53 requests made each 5 minutes between 9am and 14pm on May 2013.
