The system that is proposed is an early warning system that can provide valuable minutes that would help in mitigation of disasters like landslide and floods. The system comprises of a wireless sensor network established on slopes of a mountainside which are prone to landslides and floods. The network established is based on a Node MCU topology. For purpose of demonstration, a two node system has been proposed. The nodes will measure precipitation using a tipping rain sensor and landslides using accelerometer that observes the change in position of the module. It also has an Humidity sensor which continuously monitors the surface temperature changes. These nodes would report to a base station and to the public people which would have a Node MCU microcontroller as a receiver. This unit, called the base unit will communicate with a master unit using a long range transmitter. This unit will be suitably located at a location, say, for example at the district collector. When landslide and flood detected by the nodes is larger in a given time period, so as to produce a flash flood, this information is sent to the master unit. The master unit sounds an alarm and sends message to related officials and people via a Node MCU microcontroller interfaced with it.
