 Make sure the input voltage is not from 0.5 VDC to 1.5 VDC as the electric status between
these two values are not stable.
 The breakdown voltage is 30 VDC, and keep voltage stable.
 To prevent damage to the GPIO pin, please connect GND first and then input voltage in Line 2.
Line 2 Configured as Output
When the environment temperature is 25 °C (77 °F), the relation among external voltage,
resistance and the output level low is shown below.
