As shown in the picture. This system uses the internal temperature sensor to measure the room temperature. And it uses a 2N3904 type transistor's emitter polar to measure the remote temperature. Other input channels are used to measure the differencial voltage and 0~+5V single-port voltage. The MAX1298/1299 is connected to the uC through the serial interfaces.
