Single-wire interface digital output air pressure sensor

Product Description

The M1711F120D is a high-precision tire or air pump pressure sensor with a single-wire interface based on an FR4 substrate. The sensor contains a high-linearity MEMS pressure chip and a fast ADC. The ADC data output refresh cycle can reach about 1.8ms. It uses a simple single-wire interface communication protocol and can interface with almost any microcontroller.
The MEMS pressure sensing principle, signal processing method and unique packaging calibration process of the M1711F120D can ensure that the sensor has low pressure hysteresis, temperature hysteresis and high stability.

Question:
I am trying to interface this pressure sensor with the arduino but the problem is the ADC is builtin and digital output is coming from the sensor. I dont know how many bits resolution is used. The problem is that how i read the sensor output value. Please provide the simple sample code for reading the digital value of the sensor.
If want to use any library then also you can use.

@abd42
Do you have a link to a datasheet
or a link where you bought the device?

Found only - http://www.mzys-tech.com/acp_view.asp?id=17

Same problem
i also only found that website there is no datasheet available.
The only information available is on that website which maybe incomplete for interfacing with microcontroller

4

I left a message at their site with a request for the datasheet and protocol.
As it is weekend, we'll have to wait for some days.

I also have 1 more version of pressure sensor from the same company whose description is as follows:

mV output air pressure sensor M1709F

Product Description

M1709F is a silicon piezoresistive absolute pressure sensor with mV output and a full scale of 700 or 1500kPa. This product uses neutral soft transparent silicone protection, which can effectively prevent moisture while ensuring high linearity, high sensitivity, low temperature drift and high reliability. It is widely used in products related to air pressure. M1709F has a mature and stable process, which can ensure the performance consistency and stability of mass-produced products. The range can be customized.

I think that its output is analog not digital?

6

Does it have some datasheet link?

7

No
Same like with above sensor
only information available on website
No datasheets available

Ghe, from the same manufacturer

The description says a mV (millivolt) output, so it is analog.
Then one can assume (or not) it is linear over the range mentioned.
It does not tell the mV range (1-10 mV 100mV 1000mV ) ???

At least easier to interface and with some tools one could reverse engineer the formula.
(I think)

How high or low air pressure do you want to measure?

11

upto 130 140 psi
I want to use to measure tyre pressure of large vehicles

12

Bought a sensor like this ago... should start using it.

Going to use it for automatic tire inflation up to a preset pressure, but for much smaller 'vehicles'. :upside_down_face:

13

3 different models?

14

No
He is saying that what can be the change in millivolts
is it 10mV or 100mV or 1V?
as there is no datasheet available so there is not complete information

15

No just an indication that we do not know the range

(crosspost :slight_smile:

That's it. :saxophone:

I hope it's not 230 000 mV.

It's stupid that a sensor get three hits on google, first one is this thread, the other two are the manufacturer.

18

I'm looking for a source for this sensor for a repair project. Can anyone help? TIA

19

sorry, so far nobody succeeded to find any information other than mentioned above.
