Data logger : Main circuit
This is a busy module and again this employs a PICAXE18X chip. It has the following interfaces:
• A serial interface to the User Interface PICAXE.
• An Output driving an LED to indicate when new data has been received from the Outdoor Unit.
• A serial download connection to receive program downloads from the PC.
• A standard Data-link circuit to allow the PICAXE to send stored Sensor data out to the PC.
• Inputs from the local DS18B20 and MPX4115 sensors.
• I2C interface, via Outputs 1 and 4, to the 24LC256 memory chips.
• Two wire connection to the Receiver PICAXE.
• A serial interface to the User Interface PICAXE.
