Issue reading pressure transducers and getting floating value
The analogRead() method returns an integer between 0 and 1023 on a 0-5V swing. Your transducer produces a 0.5V - 4.5V range (from the datasheet you linked to). That's a 4V swing. So analogRead() can …

Switching low power with transistor
A more standard value will be 4700 ohms, it little lower drain on the Arduino pin and a bit less delivered current with the PN2222's beta. … Keys to look for are:
Limiting bias current from the Arduino to the base of the transistor. …
