Description

The HX710B pressure sensor module interposer is a signal conditioning board built around the HX710B 24-bit analog-to-digital converter. It is designed to interface with external membrane-type pressure sensors, providing amplification, filtering, and digital conversion of the analog strain gauge output. The module outputs a high-resolution digital signal via a simple serial interface, making it suitable for direct connection to microcontroller GPIO pins.

Engineered for stability across a wide temperature range from -40°C to +85°C, this interposer is ideal for embedded systems requiring precise differential or gauge pressure monitoring. Its selectable gain settings allow for optimization with sensors of different sensitivities, ensuring accurate readings across the full 0 to 40 kPa measurement range.

Frequently Asked Questions

What is the primary function of this HX710B module?

This module is an interposer or signal conditioner. It houses the HX710B 24-bit ADC to amplify, filter, and digitize the analog output from an external membrane pressure sensor (not included), providing a clean digital serial signal for microcontrollers.

What microcontrollers is this pressure module compatible with?

It is directly compatible with any 3.3V or 5V logic microcontroller that can read a serial data stream, such as Arduino (Uno, Mega), ESP32, ESP8266, Raspberry Pi Pico, and STM32 boards. The interface typically uses simple GPIO pins for data and clock.

How do I select the gain setting on the HX710B module?

The gain (32, 64, or 128) is typically selected by the timing sequence of the input clock pulses sent by the microcontroller via the serial interface. You must configure your firmware to generate the correct pulse pattern corresponding to your desired gain setting for your specific sensor's output range.

Can this module measure absolute pressure or only differential pressure?

The HX710B ADC itself measures differential voltage. The pressure measurement type (gauge, differential, or absolute) depends entirely on the external sensor you connect. This interposer module conditions the sensor's signal but does not define the pressure reference.
