YE5955-L type lora wireless sensor

YE5955 wireless sensor is a new type of vibration measuring instrument integrating the Internet of Things and vibration sensors. The measuring instrument integrates a vibration sensor, a high-performance low-power ARM processor, a 16-bit AD converter and a digital signal processing unit. YE5955-L communicates directly with the host computer through lora, and transmits the vibration temperature characteristic information to the host computer. At present, there are mainly two types, one is based on custom protocol transmission, and the other is based on lorawan transmission.
