eth_rem_flowercare-3.2.tar.gz	mtime: 2010-07-13, size: 580219 bytes supported MCUs: atmega168, atmega328p, atmega644	This tar.gz file contains besides the actual source code also the circuit diagram. Changes since last version: Show absolute time for next timer based watering. Support for atmega644
The above software version supports atmega644/atmega644a. There is a difference as to how the capacitive humidity sensor is connected. The above software uses 95% of the space on an atmega168, about 50% of an atmega328p and about 25% of an atmega644. Pinout for atmega644/atmega644a based ethernet boards: DS18S20 data pin = atmega pin PD6 Capacitive humidity sensor, tone output pin = OC0A = atmega pin PB3 Capacitive humidity sensor, precision rectifier output signal = ADC0 = atmega pin PA0 Manual watering button = atmega pin PB0 Dry soil LED (blinking) = between atmega pin PB1 and GND Pump control (to relay driver) = PD7 Pinout for atmega168/atmega328p based ethernet boards: DS18S20 data pin = atmega pin PD6 Capacitive humidity sensor, tone output pin = OC0B = atmega pin PD5 Capacitive humidity sensor, precision rectifier output signal = ADC0 = atmega pin PC0 Manual watering button = atmega pin PB0 Dry soil LED (blinking) = between atmega pin PB1 and GND Pump control (to relay driver) = PD7
eth_rem_flowercare-3.1.tar.gz	mtime: 2010-07-01, size: 572945 bytes supported MCUs: atmega168,atmega328p	This tar.gz file contains besides the actual source code also the circuit diagram. Changes since last version: Better interference resistance on manual watering button. Clock system tuned for accuracy.
eth_rem_flowercare-3.0.tar.gz	mtime: 2010-06-20, size: 572493 bytes supported MCUs: atmega168,atmega328p	This tar.gz file contains besides the actual source code also the circuit diagram. Changes since last version: added automatic timer function
Version 3.0 introduces a new feature: a timer to water the plants automatically every day. You can set it up to water always at a given time or only if the soil is dry.
eth_rem_flowercare-2.0.tar.gz	mtime: 2010-03-18, size: 127429 bytes supported MCUs: atmega168,atmega328p	This tar.gz file contains besides the actual source code also the circuit diagram. Changes since last version: added a local push button to start/stop watering manually
Version 2.0 introduces a new feature: a push button connected between GND and pin PB0 can be used to start/stop watering manually. You can configure for how long the water should flow when the push button is pressed. That time is in seconds but it can be a large number (e.g 1800=30min). This allows you to use the system for a pot plant that might just need water for 10sec as well as for a lawn which you want to water for 20min.
