What sensor are you talking about, there are lots of sensors for the Arduino.

If you then want to send the data to an Android device (as you have posed the question in the Android forum), you can transmit/send the readings via either Bluetooth or MQTT.

I use b4A.
on Arduino Uno A0 pin input voltage sensor.
data is sent via bluetooth to an android smartphone.
is there an example of a simple b4a program that displays data coming from bluetooth.
