I need a circuit board designed to transmit data from these 2 or 3 sensors to either Teensy or Arduino so that the data can be read. Nitric Oxide (NO) NO-A1 Ammonia NH3-AF Oxygen O2-A2 I am not sure if I will include the O2 one or not as there is another sensor already built with the transmitter circuit board. The sensors will be measure subtle amounts of these substances in the human breath. I have linked the data sheet for each sensor and digital and analogue transmitter information. NO-A1 [login to view URL] NH3-AF [login to view URL] O2-A2 [login to view URL] Digital Transmitter - [login to view URL] Analogue Transmitter - [login to view URL] The person I choose needs to be an expert at designing these circuit transmitter and do an exceptional job.
