+1.	Question text:
+Amonia Sensor
+
+2.	Design summary:
+	Fairly well written.
+	Your worst case design is ok.
+	Could have added a calibration step / method to calibrate at known gas conc.
+	What happens if there is a problem with the sensor? The clean air level
+	should fall below 2mV and that should trigger a different warning/alarm also.
+
+3.	Block diagram
+	
+4.	Power supply design
+
+5.	Industrial Design:
+
+6.	KICAD Design
+	Schematic:
+	Circuit design is ok overall. Could have added more functionality
+	
+	PCB:
+	Layout is too loose.
+	Transformer need not be board mounted - too much weight.
+	If all your components are SMD layout could be tighter.
+	
+7.	Pricing / BOM / Assembly
+	Final prixing?
