 +  * //Might have to use a Mega due to need for multiple baud rates.// 
 +  * http://www.seeedstudio.com/wiki/Seeeduino_Stalker_v2.3 
 +  * Will need to turn phone and the arduino on and off to save energy
 ==== Communication ==== ==== Communication ====
 +  * Use a Motorola C168i controlled by Arduino via serial library to send text messages. [[http://jeffmurchison.com/blog/send-sms-from-your-arduino/|Tutorial]] 
 +  * Cost of sending international texts using Safaricom is approx. 11 cents/text. [[http://www.safaricom.co.ke/personal/prepay/sms|Safaricom Rates]]
 ==== Sensors ==== ==== Sensors ====
 +  * Dissolved Oxygen  
 +    * [[http://atlas-scientific.com/product_pages/kits/do-kit.html|Atlas Scientific Probe]] - They have sample arduino code. Calibration is good for atleast 12 months after initial calibration -- **$200** 
 +  * Ammonia  
 +    * Ammonia probes are very expensive (>$400)  
 +    * Instead, use [[http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=4387|Ammonia Alert Device]] coupled with a [[https://www.atlas-scientific.com/product_pages/sensors/env-rgb.html|color sensor]] to determine concentration. //Will need to place sensor close (< 3-4 mm) to the alert device and possible use a light source for accurate readings// 
 +  * Nitrate 
 +  * pH 
 +    * [[http://atlas-scientific.com/product_pages/kits/ph-kit.html|Atlas Scientific Probe]] - //"Remember, a pH Sensor cannot be allowed to dry out or freeze. When it’s not in use keep it in the supplied soaker bottle. Periodically change out the storage solution in the soaker bottle with new storage solution. This pH Sensor can be fully submerged indefinitely."// -- **$106**
