Finding a good pressure sensor can be tough. Some seem so cheap they couldn’t possibly have any meaningful accuracy, while others are so expensive, how could anyone use them? The Atlas Scientific EZO-PRS is a digital pressure sensor that provides the accuracy you need at a reasonable cost. The sensor can read the pressure of a liquid, gas, or oil from 0 – 74 psi.
The EZO-PRS™ comes with:
One embedded pressure sensor, and one data cable with 5 pin male header.
