Hydropal: Arduino Branch

Description

This is the repository Arduino code for the Hydropal smart water bottle JA company. The code will primarily allow the Arduino Pro Mini board to read the ml/sec of liquids going though the nozzle of the bottle in order to measure the millitres of water that a person drinks throughout the day. It also syncs that data to a mobile device.

Code for the water bottle itself is in the 'Hydropal' folder!

Usage

Detailed instructions can be found here: https://github.com/Hydropal/Hydropal-Arduino/wiki

Current Functionality

• Checks sensor reading every second to find ml/sec passing through sensor
• Adds sensor reading to total ml of liquid consumed throughout the day
• Reset total counter midnight every day
• Update correct date and time over Bluetooth
• Update user preferences over Bluetooth
• Send multiple day data over Bluetooth
• Pulsing LED to remind user to sync
• Blinking LED to remind user to drink
• Proper sleep wake to control LED
• Adjusts internal data to reflect time changes and disreprencies (should work in different timezones)
• Checks if sync data is valid

Deprecated Functionality

• LED indicators for total volume consumed, for 5 LEDs (present in Alpha 2.0)

To-do

• Flow rate calibration

Changelog

Release 1.0

• Checks if time from device mismatches internal clock and shifts volume array backwards and forwards as necessary
• Checks if data sent from device is corrupted over transmission and should help prevent errors that require a hard reset
• Change baud rate to 38400 instead of 112000 to lower chances of data corruption during transmission

Alpha 6.0

• Arduino checks for the largest value and sends it back to the device
• LED pulses when need sync
• LED blinks when need drink

Alpha 5.0

• Groundwork for sleep wake times
• Groundwork for pulsing LED
• Multiple day data is sent and reset

Alpha 4.0

• Data is sent to mobile device over Bluetooth
• Data from mobile device is parsed: things such as time and user preferences are updated

Alpha 3.0

• Water consumed is now reset every midnight

Alpha 2.0

• LEDs can indicate how much has been consumed, one for each 1 L
• LEDs in progress of being filled up blink

Alpha 1.0

• Initial release
• Measures flowrate in ml/sec and adds up to total water consumed
