Six small green circuit boards with black chips and pin headers

KEHIPI

KEHIPI Hx711 6pcs Load Cell ADC Module Electrical System Tool

SKU CH-XK1Y-GXYSA

Six HX711 ADC modules convert load-cell signals with selectable 32, 64 or 128 gain and 10 or 80 SPS output rates

  • Width7.5 in
  • Two selectable differential input channels for flexible sensor wiring
  • On-chip low-noise PGA with selectable gain of 32, 64 and 128
  • Simple pin-driven digital control and serial interface, no programming needed
  • Selectable 10SPS or 80SPS output data rate for speed or resolution
  • Simultaneous 50 and 60Hz supply rejection for cleaner readings

Six-Channel ADC Kit for Weight Sensing

This pack contains six HX711 modules that convert load-cell signals into digital data. Each board integrates a 24-bit converter, a low-noise programmable gain amplifier and an on-board regulator so the sensor bridge and ADC share a clean supply. The pin-driven interface needs no firmware, making it straightforward to add precise force or weight measurement to a microcontroller project.

For Experimenters Building Scales or Force Sensors

Makers designing laboratory balances, industrial hoppers or structural test rigs will appreciate the selectable 32, 64 or 128 gain and the dual differential inputs per module. The 10 or 80 samples-per-second rates suit static or slow-dynamic loads, while simultaneous 50 and 60 Hz rejection keeps mains noise out. Engineers needing faster throughput, higher channel counts or integrated temperature compensation should evaluate alternative ADC architectures.

24-Bit Resolution With Programmable Gain

The defining specification is the on-chip 24-bit A/D converter paired with a PGA offering gains of 32, 64 and 128. This combination resolves microvolt-level changes from a Wheatstone bridge, letting a single module measure strain, pressure, displacement or torque without external amplification. The 2.6 to 5.5 V supply range and -40 to +85 °C operating window complete the core capability.

Questions about this item

What are the physical dimensions of each HX711 module so I can plan my enclosure layout?

Each module measures approximately 25 mm by 16 mm (0.98 in by 0.62 in), so allow at least that footprint per board plus wiring clearance.

Which pins must be connected to select the gain setting and data rate during installation?

The gain of 32, 64 or 128 and the output rate of 10 SPS or 80 SPS are chosen by driving the on-board control pins; the most common mistake is leaving the gain-select pins floating instead of tying them to VCC or GND.

What operating voltage range and temperature limits should I design for to avoid later replacement?

The module runs from 2.6 V to 5.5 V and is rated for -40 °C to +85 °C; keep your supply within that window and provide adequate ventilation if the enclosure approaches the upper temperature limit.
