Pressure sensor board.

HI,
Recently i buy a pressure sensor on a board with a HX710B chip, Has any one info about this sensor. the Chinese seller could not help me further.
There are 4 connextions VCC and GND and out and SCK.
Regards Rien.

@pa3gmi according to this Chinese datasheet https://datasheetspdf.com/datasheet/download.php?id=810335 the supply is 5.5v maximum.
It also contains some example code, but comments are in Chinese.

The hx710 might be nearly identical to the hx711 which is all over the internet, eg https://learn.sparkfun.com/tutorials/load-cell-amplifier-hx711-breakout-hookup-guide
You could give a hx711 library a try and see what happens.

@yveaux
You are correct checking the data sheet the output format of the two chips is in a similar format.

If the HX711 libraries are used then the using HX711 options
HX711 Channel A gain 128 selected === HX710B Differential reading of sensor at 10Hz speed

HX711 Channel B gain 32 selected ==== HX710B Digital Voltage-Analog Voltage Reading

HX711 Channel A gain 64 selected ==== HX710B Differential reading of sensor at 40Hz speed

Thanks for suggestions I try to get things working.

Hi,

Yes it works, calibration is also possible. I will use it to measure the ground water level, with a bubbler. It will take time for making the right arduino sketch to send the measurement to Domoticz. I just beginning with it and I am almost 70. I will use the Nano and NRF24L01 and the Sensbender gateway for it.
