Description

Having 20 Pressure Sensor
2 Temperature Sensor
1 Arduino mega
1 Dc jack for power supply the mega and other pcb

AMS117 is use for only sensors not mega,  mega is taking directly from DC jack
miso and mosi is connected with each other with 1K resistor for 3 wire SPI interface.
ractangle pcb should not exceed 20 mm in width length can be variable

C1, C2 is for Temperature Sensor across power supply

C3 - C22  For Pressure sensor across power supply

R1 & R2 is pullup for Alert pin in temperature sensor
