#103109 - Some analog electronics will be needed Responding to: ???'s previous message |
John said:
does this mean, i need to develop a circuit which the output of the sensor is amplified before connecting to the input of ADC? Some sort of analog electronics will be needed, yes. First, analyse how precise your circuit must be. Must there be a correction of temperature and/or humidity dependency? This will tell you, whether temperature and/or humidity must be measured too. Second, find out, which gas concentration (contamination) is to be measured. This will gide you in finding the proper load resistor. When having all this information you can start to design the analog front end electronics. Kai |
