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.
Temperature Sensor TMP36 (https://www.sparkfun.com/products/10988) Pulse Sensor (https://www.sparkfun.com/products/11574) Carbon Monoxide Sensor - MQ-7 (https://www.sparkfun.com/products/9403) Air Quality Control Sensor MQ135 (http://www.futurlec.com/Gas_Sensors.shtml) 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 (https://www.sparkfun.com/products/10161) 2X Polymer Lithium Ion Battery - 2000mAh (https://www.sparkfun.com/products/8483) Momentary Push Button Switch - 12mm Square (https://www.sparkfun.com/products/9190)
My only big parts left to do are; 1. Change the code I have for a serial my 16X2 LCD (https://www.sparkfun.com/products/9069) to the GLCD. 2. Make the housing for everything 3. hook it up.
So a few thing I have questions about. 1. 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? 2. 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?
