Load Cell Sensor (H26R0x)


SKU: H26R00 Category:

Load Cell (Strain Gauge) Sensor

Stage: Beta

Available on backorder


H26R0x is a load cell (strain gauge) sensor interface module based on Avia Semiconductor HX711 Wheatstone bridge ADC and STM32F0 MCU. This module is a precision 24-bit analog-to-digital converter (ADC) designed for weigh scales and industrial control applications. It interfaces to load cells (strain gauges) in a Wheatstone bridge configuration. The module accepts a full bridge (5-pin connection) as well as a secondary sensor connection (2 pins).

  • Use this module to build digital scales for home, commercial and industrial applications.
  • Combine with other Hexabitz hardware to add industrial I/Os or communication capabilities (RS485, Ethernet, CAN, BLE) to your industrial and commercial weight scales.
  • Program advanced C code using our easy-to-use APIs and messaging system.
  • Connect to external hardware or combine with other Hexabitz modules!



  • Avia Semiconductor HX711 24-Bit Analog-to-Digital Converter (ADC) for Weigh Scales:
    • 24-bit precision with two selectable differential input channels.
    • Low noise PGA with selectable gain of 32, 64 and 128.
