Airspeed Breakout Board APM 2.5 MPXV7002DP
You may check the tires' inflation pressure using the meter installed on the pressurized air pump, or you could use this sensor to attach to your DIY pressure air pump.
This sensor is a high-quality pressure sensor. It can measure pressure with a range of -2kPa to 2kPa. It needs a 5V power supply. The marginal error for this sensor is +-2.5. It is a pretty fast responding sensor with a response time of 1ms. The sensor's sensitivity is at 1V/kPa.
You could use this in projects that have air pressure monitoring functions in it.
The MPXV7002 series piezoresistive transducer in the small outline package (SOP) is a state-of-the-art monolithic silicon pressure sensor designed for a wide range of applications, but particularly those employing a microcontroller or microprocessor with A/D inputs. It is patented. It incorporates a single element transducer that combines advanced micromachining techniques. It has a thin-film metallization, and bipolar processing to provide an accurate, high-level analog output signal that is proportional to the applied pressure.
MPXV7002 can measure positive and negative pressure. The offset is at 2.5V instead of the conventional 0V; this new series allows us to measure pressure up to 7kPa through each port for pressure sensing.
