Hi, we want to develop a PCB which integrates the capabilities of arduino + GSM (SIM808/900) module + memory card module. It should have 4 analog inputs (all the other extra components of arduino can be avoided) where we will be connecting our temperature sensors. The PCB should also have the required components for supplying power supply to all the components (a kind of built in SMPS (AC-DC 240V-5V)).The circuit for temperature sensor is included in files. The circuit shown in [login to view URL] is for 3 temperature sensor this can be extended to 4. The temperature sensor circuit is very sensitive to noisy environments, therefore noise reduction components should be present.
