Product description: Gravity - analog water pressure sensor - DFRobot SEN0257
Analog sensor designed to measure water pressure, manufactured by DFRobot. It uses a 3-pin Gravity interface. The supported input voltage (standard) is equal to 5 V, and the linear output voltage ranges from 0.5 V to 4.5 V. The sensor is compatible with controllers such as Arduino and can be used in a wide range of smart home control systems (SCS) or Internet of Things (IoT).
Arduino compatible product
The manufacturer has prepared a detailed user's guide, which includes a description of projects using the sensor and sample program code.
Gravity: analog water pressure sensor - Arduino compatible - DFRobot SEN0257.
Sensor has leads in form of wires with BLS connector in three colors.
Sensor leads description and connection diagram
Sensor terminals are wires with BLS connector available in three colors: red, black and yellow. Module is compatible with Arduino and derived boards. On the example diagram, the DFRduino board is used (available for purchase separately). In order to obtain correct operation of the element it is necessary to connect the leads with the controller board according to the following dependencies:
- red wire - VCC - power supply 5 V
- black wire - GND - GND - Ground
- yellow wire - Signal - analog signal (output from 0.5 V to 4.5 V)
