Gravity-Sensing Unmanned Vending Cabinet Solution

Advances in IoT, microprocessor, and sensor technologies, combined with growing consumer demand for higher-quality lifestyles, have accelerated the retail industry into the unmanned vending era. Smart devices, such as gravity-sensing vending machines, have become a market hotspot.

Leveraging its strong expertise in weighing sensors, Hualanhai Electronic Measurement has collaborated with multiple domestic unmanned vending machine manufacturers to provide various gravity-sensing units. Depending on customer applications and cabinet structures, Hualanhai offers single-sensor, dual-sensor, and four-sensor gravity units with analog or digital output.

The sensor’s core strain gauge is made in-house using imported raw materials, ensuring superior performance. Gravity units cover a range of 10–120 kg with precision up to 0.02%, and can be customized for temperature stability and creep performance. These gravity-sensing units are also suitable for open shelves, warehouse racks, and other scenarios requiring smart inventory management.
