I recently purchased the UST triple gas sensor, along with 12 other gas sensors from the company Umweltsensortechnik in Germany. See link https://www.umweltsensortechnik.de/en/gas-sensors/ust-triplesensorR.html. However, their data sheet contains limited information on how to connect the sensors to a simple circuit. I've sent them five emails asking questions but I've got no responses. Does anybody know how to build a simple circuit for the UST triple sensor? The main problem I have is that it uses a Y-network. I know how to convert from Y to Delta and vice-versa, but how to get the voltages afterwards is where I'm stuck. I have added a picture of the sensor layout. Any help will be appreciated. Thank you.
I think I have a partial answer but am not 100 % sure. I converted the Y-network to a Delta network and then connected the pins. Note that the final network is what UST UST Umweltsensortechnik gmbh recommends (see file German_sensors_network1.jpg file). Any thoughts will be appreciated.
