Output
Note: Customer has to select suitable resistors for chosen supply voltage. Pull-up resistor
RP could be e.g. 10 kΩ depending on desired output. Forward voltage of LED is 1.3 V
and LED current should be 10 mA (depending on application liquid).
RLED can be calculated as follows (e.g. for VS=12 V):
RLED =
( VS − 1.3) V 12 − 1.3
=
= 1070 Ω ≈ 1.1 kΩ
