Wireless full-bridge sensor gateway
A single gateway supports 4 full-bridge and half-bridge strain sensors. The gateway integrates power supply, acquisition and transmission. It can be cascaded and powered via a data bus. Ultra-low power consumption, built-in battery, can be used without external power supply, easy to detect.
