UNIT Scales is a high precision low-cost I2C port weighing sensor, with a total weighing range of 20kgs. Adopt STM32F030 as the controller, HX711 as sampling chip and 20 kgs weighing sensor. With tare button and programable RGB LED. This Unit offers the customer with a highly integrated weighing solution, suitable for the applications of weighing, item counting, item movement Checking and so on.
HX711:
High precision 24bit ADC
Programmable gain amplification 32, 64 and 128
10SPS output data rate
I2C port
Development platform: Arduino, UIFlow(To be supported soon)
After using ATOM to power on with Demo, you need to press the button to return to zero, otherwise the measurement is inaccurate.
