LoRa communication landslide sensor
It will be used for safety management of workers during construction work (such as dam construction and protective fence construction) in rivers at risk of landslides.
When the wire sensor upstream of the river breaks, an alarm signal is transmitted via LoRa wireless (which allows for long-distance communication) from the transmitter to the alarm receiver installed downstream. The receiver that receives the alarm signal will activate the connected alarm devices. Various alarm devices (outdoor and indoor alarms, as well as email notification devices) can be connected to the downstream receiver. The receiver typically receives wireless signals from the transmitter and outputs (contact output, voltage output), but if wireless communication is not needed, the wire sensor drawn from upstream can be directly connected to the contact input of the internal timer unit without using the transmitter, allowing it to be used as a wired debris flow sensor.
