Gravity Analog Water Pressure Sensor 0-10 Bar

The Gravity water pressure sensor from DFRobot measures the pressure in water pipes and tanks and outputs it as a linear voltage of 0.5 to 4.5 V. It runs on 5 V and connects via the fixed 1 m cable with a 3-pin Gravity connector, for example to a Gravity IO Expansion Shield. The G1/4 thread and the mounted G1/2 to G1/4 adapter fit common pipe fittings.

Important: DFRobot now specifies a measuring range of 0 to 1.6 MPa (16 bar), which is also printed on the label of the current version. The example in the wiki calculates with 0 to 1 MPa. For converting the voltage, the range on the sensor label applies.

Note: The connection cable can be converted to male pins with a Dupont cable M-M, so that it also fits an Arduino UNO.

Recommended Accessories:

Features:

Linear output voltage 0.5 to 4.5 V at 5 V supply
For liquids and gases that are not corrosive
Waterproof to IP68
Response time below 2 ms
G1/4 thread, G1/2 to G1/4 adapter mounted and removable
Calibrate the zero point in the DFRobot example using the voltage without pressure
The cable can be extended; too long or poor wires falsify the reading (DFRobot)

Application Examples:

Water pressure in household pipes and garden irrigation
Pressure in tanks and pump systems, together with a solenoid valve
Level via the pressure of a liquid column
Detecting pressure drop and leaks
