THE SOLE PROPERTY OF SIA MIPEX. ANY REPRODUCTION WITHOUT THE WRITTEN PERMISSION OF SIA MIPEX IS PROHIBITED.

Fig. 6. Connection diagram of multiple sensors to single UART line

Resistors are calculated as follows:

1. Determine the quantity of sensors

N

that should be connected to single UART line.

2. Determine forward voltage

U

f

of Schottky diodes (VD_N).

3. Calculate the minimum allowed resistance

R

min

by using the following equation:

R

!"#

I

&'(

× (N − 1) ,

where:

U

h

– maximum high logic level voltage (2.7 V);

I

out

– maximum output current of sensor microcontroller (25 mA).
