So I have a project that I have been working on and it has come a long way and its close to completion. I wanted to build sensor micro-controller that senses Carbon monoxide, air quality, Temperature and human pulse and display it on a GLCD. I want it to be portable so it will be powered by LIPO batteries. Here is a list of parts that I will be using in the project. I have tested and written code for all the sensors except the pulse sensor,which I'm doing now until all the remaining parts come in. If anyone can see anything i forgot to add or If you have suggestions on what else I could add please let me know. Also let me know what you think of my project.
GLCD (https://www.sparkfun.com/products/9351)
Arduino Pro Mini 328 - 5V/16MHz (https://www.sparkfun.com/products/11113)
Temperature Sensor TMP36 (Temperature Sensor - TMP36 - SEN-10988 - SparkFun Electronics)
Pulse Sensor (Pulse Sensor - SEN-11574 - SparkFun Electronics)
Carbon Monoxide Sensor - MQ-7 (https://www.sparkfun.com/products/9403)
Air Quality Control Sensor MQ135 (Gas Sensors)
Flashlist SUPER BRIGHT WHITE, SUPERFLUX LED (http://www.allelectronics.com/make-a-store/item/LED-918/SUPER-BRIGHT-WHITE-SUPERFLUX-LED/1.html)
USB LiPoly Charger - Single Cell (SparkFun USB LiPoly Charger - Single Cell - PRT-12711 - SparkFun Electronics)
2X Polymer Lithium Ion Battery - 2000mAh (https://www.sparkfun.com/products/8483)
Momentary Push Button Switch - 12mm Square (Momentary Pushbutton Switch - 12mm Square - COM-09190 - SparkFun Electronics)
My only big parts left to do are;
- Change the code I have for a serial my 16X2 LCD (SparkFun Serial Enabled 16x2 LCD - Amber on Black 3.3V - LCD-09069 - SparkFun Electronics) to the GLCD.
- Make the housing for everything
- hook it up.
So a few thing I have questions about.
- If i put two 3.7V LIP batteries in series to get 7.2V will the above LIPOly charger still charge them since its the same current?
- I've been using a Arduino Uno/RedBoard to do all my prototyping will I be able to easily go to the Pro Mini without losing anything?
