Distanceup to 8Km in open area. 16 channels to choose. Parameters set wirelessly by PC. Real time / Timing mode. Sensitivityup to -121 dBm. Home automation remote sensing. Building automation and security. Note: Below parameters base on 12V power supply/ 25 testing environment. Master dont send message. The description of interfaces as below. The input port is pulled up internally, leave open or connect with 3.3V will result in high level, it is low level when connect to GND. High level will make the output of the other side short out. And low level will make the output of the other side open. Below is regular connection. Mechanical dimension(Unit: mm).
