This repository contains project about a temperature sensor based on Xbee device. It will be coupled with the zigbee controler and the web_monitoring projets to resp. retrieve the value from the sensor and display thought a web site.

The hardware folder groups schematics. it is based on a PIC device (PIC18LF2420) coupled with a XBee module (from Digi) Temperature and Humidity sensor is a HYT221

The folder contains source code to build the firmware for the PIC device.

• read temperature and humidity around each minutes
• read the battery voltage
• PIC clock calibration Most of

• acquisition period will be reviewed to improve consumption

autonomy test on going, with hourly reception of battery value and reception of temp/humidity each minutes

• estimation: more than 6 months if I interpolate the current consumption.
