HX711 Calibration for Arduino. HX711 is a Load Cell Amplifier module with precision 24-bit analogto-digital converter (ADC) designed for weigh scales and industrial control applications to interface directly with a bridge sensor. It can be used to measure weight in various ranges. Your load cell probably has a wheatstone bridge inside for thermal stability and a stronger output signal. •Four-Channel Differential Input (ADS1234) performed on-demand and the ADS1232/4 can be put in a low-power standby mode or shut off •Simple Serial Digital Interface completely in power-down mode. After a reset or power-down event, input selection is default to Channel A with a gain of 128. Mouser offers inventory, pricing, & datasheets for HX711. 0000003164 00000 n
