ZE07-CO is a general-purpose and miniaturization electrochemical carbon monoxide detection module. It utilizes electrochemical principle to detect CO in air which makes the module with high selectivity and stability. Built-in temperature sensor can do temperature compensation; and it has digital output and analog voltage output.
Electrical connections for the various sensor cells are by means of connector pins on the top surface of the sensor cells. A sensor wiring assembly provides the electrical interface between the sensor cell and the Amplifier PCB. The sensor cell plugs into the Connector Board on the sensor wiring assembly and the wiring harness connects to the amplifier PCB (connector J6).

Diagram shows connection between one or more devices wired to an exhaust fan using the fan setpoint relay(s). This function can be performed by a single TG sensor or a sequence of multiple TG sensors wired in parallel. If wiring multiple sensors, ensure that the fan relay setpoints are uniformly set. The fan relay will activate if any sensor
The ideal configuration is to leave the sensor continuously biased and power cycle the rest of the monitoring device. This reference design describes the design of a nano-power, potentiostat-type electrochemical sensor circuit. While this design uses a three-terminal CO gas sensor as an example, the basic example circuit
