Embodiment 1
[0059] like Figure 1-3 , a kind of debris flow monitoring and early warning sensor device based on wireless ad hoc network, including MCU, battery, three-axis acceleration sensor, geoacoustic sensor, vibration sensor, battery voltage detection circuit and power management circuit, MESH network module; described acceleration sensor , geoacoustic sensor, vibration sensor, and battery voltage detection circuit are all connected to the input interface of the MCU through the A / D converter (including the ADC that comes with the MCU), and the MESH network controller is connected to the MCU. [It can monitor the acceleration and inclination of the sensor caused by the movement and deformation of the soil. It can also monitor the vibration caused by the movement of sand and soil around the sensor at the same time, and it can also monitor the low-frequency ground sound generated by the debris flow at the same time. 】【MCU is a micro-power microcontroller】
[0060] The described debris f...
