| Abstract: | An interface circuit for multi-channel sensors is introduced in this paper. While an equal-scale pulse generator exciting the multi-channel sensors, a ADC, composed with a serial DAC and a comparator, controlled by the 87C51 SCM, completes digitization of the multi-channel. A 12-bit ADC has been developed using 5V pulse generator to impel the sensors such as conductivity, temperature, depth, pH, dissolved oxygen and reference. This interface circuit is simple and economical, and suitable for water quality monitoring. |
