Domotic-Gas Counter data logger with a 18F PIC controller

This is a datalogger project for a Gas counter equiped with a pulse output.

The project is equipped with a RTC and a EEPROM and a T° sensor from chipworld  :

2PCS-Real-Time-Clock-Module-AT24C32-ds1307-for-arduino-I2C-RTC-AVR

It consists of a  controller receiving a pulse form a gas counter (one  pulse = 0.1 m3).

The pulse triggers an interrupt.

Each pulse is recorded in a EEPROM of 4.096 bytes giving 200 data of continuous log each m3 (it represents 5 to 10 days depending of the consumption) and 200 data to record end of days consumption.

A keyboard and a LCD with four menus will display data.

Now, I have to transmit the data to a gateway.

I’ll use a RFM69CW.
