Description
ADS1232 24-Bit Precision ADC Board for Load Cell and Sensors
The CJMCU-1232 ADS1232 24-bit Analog-to-Digital Converter Board is a high-precision signal acquisition module designed for bridge sensor applications such as weighing scales, strain gauges, and pressure sensors.
It integrates a low-noise programmable gain amplifier (PGA), a precision delta-sigma ADC, and an internal oscillator, delivering a complete front-end solution with minimal external components. With up to 23.5 effective bits of resolution, excellent 50Hz/60Hz noise rejection, and a simple pin-driven serial interface, this board is ideal for accurate and stable measurements in industrial and embedded systems.
The ADS1232 also includes an onboard temperature sensor to monitor ambient conditions, making it suitable for precision instrumentation and long-term measurements.
