My design contains two KiCAD projects. 1, the wall mount sensor and 2, a current signal processing hub cum alarm box.
 | 
						|
For the sake of simplicity I have made the schematics of only one sensor. There would be an addition of an OR gate after
 | 
						|
the comparator stage in order to set the alarm off in case any one of the 20 sensors detects more than 100 ppm ammonia. |
