LoRa wireless pressure alarm sensor AN-202A

AN-202A is a wireless transmission pressure transmitter developed and produced by Winext Technology Company using the LoRaWAN standard protocol. The sensor adopts a piezoresistive pressure sensor with high stability and reliability, and is packaged by low-pressure injection molding process. The overall performance is very stable and reliable. The pressure measurement range can be customized (10KPa...100MPa), and the cable length can be selected according to customer needs. Based on LoRa spread spectrum communication technology, the omnidirectional external antenna design can better transmit and receive wireless signals and improve the communication distance of wireless transmission. Low power consumption integrated design, built-in large-capacity battery; the data receiving box is durable and has an IP67 protection level, which can be used in harsh indoor and outdoor environments.
