 [[ADI>CN0396]] is single-supply, low noise, portable gas detector, using a 4-electrode electrochemical sensor, for simultaneous detection of two distinct gases. The Alphasense COH-A2 sensor, which detects carbon monoxide(CO) and hydrogen sulfide(H2S), is used in this example. Electrochemical sensors offer several advantages for instruments that detect or measure the concentration of many toxic gases. Most sensors are gas specific and have usable resolutions under one part per million (ppm) of gas concentration. [[ADI>CN0396]] is single-supply, low noise, portable gas detector, using a 4-electrode electrochemical sensor, for simultaneous detection of two distinct gases.

-The circuit shown in below uses the [[http://www.analog.com/ADA4528-2|ADA4528-2]], dual auto zero amplifier, which has a maximum offset voltage of 2.5 µV at room temperature and an industry leading 5.6 µV/√Hz of voltage noise density. In addition, the [[http://www.analog.com/AD5270|AD5270-20]] programmable rheostat is used rather than a fixed transimpedance resistor, allowing for rapid prototyping of different gas sensor systems, without changing the bill of materials. +The circuit shown in below uses the [[adi>ADA4528-2|ADA4528-2]], dual auto zero amplifier, which has a maximum offset voltage of 2.5 µV at room temperature and an industry leading 5.6 µV/√Hz of voltage noise density.

 An ADT7310 16-Bit Digital SPI Temperature Sensor is also included in the circuit to allow for monitoring of environmental temp. This allows for correction of the temperature effects on the sensor. An ADT7310 16-Bit Digital SPI Temperature Sensor is also included in the circuit to allow for monitoring of environmental temp.
