Frequently Asked Questions
Does the solution support high-precision measurement for commercial scales?
Yes. Our solution utilizes a dedicated 24-bit Delta-Sigma ADC (BH45B1225). Its high-resolution performance and low-noise architecture provide a solid foundation for developers to meet stringent accuracy requirements in commercial weighing applications.
What types of load cells are supported?
The platform supports a wide range of strain gauge load cells (single-point, shear beam, and compression types). With the BH45B1225’s internal Programmable Gain Amplifier (PGA) supporting gains from 1x to 128x, it can easily interface with load cells of varying sensitivities (e.g., 1mV/V to 3mV/V).
Does the hardware include environmental monitoring?
Yes. The BH45B1225 ADC includes a built-in temperature sensor. This allows the system to monitor ambient temperature changes, providing essential data for developers to implement their own calibration or stability algorithms.
What is the maximum weighing capacity?
The capacity is primarily determined by your choice of load cell. Our measurement platform provides the necessary resolution and stability to support applications ranging from compact kitchen scales (1kg) to industrial platform scales (500kg+).
Can the scale interface with external systems like POS or printers?
Absolutely. By pairing the ADC with our feature-rich MCUs (HT66F3195 or HT67F2355), the solution offers multiple communication interfaces including UART and I2C. This enables easy integration with Bluetooth modules, thermal printers, or POS systems.
What display types are supported by this solution?
We offer a modular approach: use the HT66F3195 for high-current LED driving (ideal for street vendors and retail) or the HT67F2355 with its integrated hardware LCD driver for multi-functional retail displays.
Does the solution meet OIML R76 standards?
Yes, our MCU's 24-bit ADC and calibration algorithms are designed to meet OIML R76 Class III accuracy requirements for commercial weighing scales.
