LoRa water level monitor AN-203A for smart community, smart industry:
AN-203A is a wireless water level monitor complied with LoRaWANTM. It is equipped with piezoresistive water level sensor and packaged with low-voltage injection molding process. The performance is stable and reliable. With LoRa spread spectrum communication technology, omnidirectional external antenna design can better transmit and receive wireless signals and improve the communication distance of wireless transmission. It has low power consumption. With built-in large capacity battery, its lifespan is more than three years. The data gathering box is robust with IP67 enclosure. It can be used in indoor and outdoor.
AN-203A is simple to install and maintain. It can be installed flexibly in the way of pole-mounting or wall-mounting on the vertical pole, lamp pole and building wall.
