Product description:
MS5837 is a new generation of high-resolution pressure sensor with I2C bus interface, with a water depth resolution of 2mm, suitable for depth measurement systems.
·Overpressure 30bar
The sensor is a digital pressure and height sensor type
·Absolute pressure type
· Output span is 24 bit ADC
The sensor module contains a high linearity pressure sensor and an ultra-low power 24-bit ¥Ä¥Ò ADC with internal factory calibration coefficients. Provide accurate 24-bit digital pressure and temperature values and different operating modes, users can configure the conversion speed and current consumption according to their needs. The high-resolution temperature output allows you to realize the functions of a depth measurement system and a thermometer without additional sensors.
MS5837 can be connected to almost any microcontroller. The communication protocol is simple, and there is no need to program the internal registers in the device. Gel protection and antimagnetic stainless steel caps ensure that the sensor module is waterproof. This new sensor module is based on advanced MEMS technology and benefits from the mature experience and expertise of MEMS Switzerland in high-volume manufacturing over the past few decades.
Advantage£º
·Ceramic metal package
·High resolution module, 0.2mbar
· Fast conversion up to 0.5ms
·Low power, 0.6uA (standby power at 25 degrees Celsius <0.1uA)
·Integrated digital pressure sensor
·Power supply voltage: 1.5v¢¦3.6v (with built-in related circuit, it can run under 5v)
·Temperature range: -20¢¦+85 degrees Celsius
·I2C interface
·With internal oscillator, no external components
·Excellent long-term stability
·Can be fully sealed, suitable for external equipment and harsh environments
After being sealed, the sensor can be used in water depths below 150m. The advantage of this sensor is that we have carried out new research and development on the basis of the original sensor, so that it can adapt to the 5v working environment, and can be directly used in the I2C port of the PIX system. There is no need to perform complex operations such as level conversion. It is specially designed for unmanned ships, underwater gliders and underwater robots of pix or raspberry pie solutions. Each of this sensor has been compensated and calibrated for temperature and pressure before leaving the factory, and each of them has been strictly tested and the quality is stable. The sensor integrates temperature and pressure dual sensors, which can directly provide actual water temperature while acquiring pressure parameters. The pressure sensor can be calibrated directly in the QGC ground station and accurate temperature and pressure information can be obtained. Sensitive and accurate.
This sensor can be used not only in scenes such as underwater robots, but also in other microcontrollers for other liquid pressure monitoring.
The sensor package shell is made of 316L stainless steel, and the sealing ring is a high-standard imported fluorine rubber sealing ring. The anti-corrosion and pressure resistance performance is better than anodized aluminum material as a whole.
The waterproof threading screw matched with the sensor is M10 specification, 1.25 pitch, better sealing.
The sensor cable is about 10cm long. If the cable is not long enough, you can contact the store owner to give a few wires.
