I intend to do a level meter for me on a display indicating the height of liquid in a tank. Given the dissatisfaction I've had with the ultrasonic sensor HC-SR04, I will begin my journey with pressure sensors.
I have been reading and MPX2010GP, requires an operational amplifier, while apparently MPXV5050GP has the following features: - No need operational amplifier circuit. - Has built-in amplifier (0 to 4.7 v). - Can be placed directly through the analog pin with just a 470 pF capacitor between the sensor and ground. - Has an entry for the air tubing and is self-ventilated to read the differential pressure. - The pins are Gnd, 5V, Signal.
Has anyone worked with this sensor? http://store.fungizmos.com/items/410
