AN-202A

The official description states that AN-202A is a wireless pressure transmitter developed and manufactured by WINEXT using the LoRaWAN standard protocol. It uses a piezoresistive pressure sensor described as highly stable and reliable, packaged using a low-pressure injection molding process, with overall performance described as very stable and reliable. The pressure measurement range can be customized (10KPa…100MPa), and the cable length can be selected according to customer requirements. Based on LoRa spread-spectrum communication technology, its external omnidirectional antenna design is described as improving wireless signal transmission and reception and extending the wireless communication distance. It features an integrated low-power design and a built-in high-capacity battery. The data receiver box is described as robust and durable, with an IP67 protection rating, and suitable for use in harsh indoor and outdoor environments.
