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.

basic information
○ The communication is powerful (super high sensitivity reception), yet it uses radio waves that anyone can use (specific low power radio). - No relay station is needed for a line of sight of up to 10 km (in the absence of obstacles) (conventional low power radios require a line of sight of 800 m). - Even for short-distance communication, it is more resistant to obstacles compared to conventional radios. ○ The transmitter has a lifespan of 1 year with commercially available batteries, and the receiver/alarm can be installed in places without power using solar power. ○ The communication device and alarm are designed with a simple structure specialized for temporary setups, making installation easy.
