Aiming at various water storage facilities, the number of which is generally large and whose distribution is not centralized in the industrial and civil buildings, this paper proposed a multi-channel water level telemetry and low power automatically warning system based on wireless sensor network. The sensor nodes of the proposed system could monitor water levels and transmit sensing data to the sink node periodically. The host server analyzed sensing data received from the sink node. Meanwhile, it made decisions according to the multi-grade cycle comparison algorithm proposed in this paper to improve the alarm accuracy.
