DWS100 series of wireless sensors have unlimited application potential. They are used for environmental monitoring, agriculture, smart buildings, health care and so on. By using smart power management even small coin cell battery may last at least one year. Communication can be secured by encryption with XTEA standard, which is optional. Accessing DWS100 sensor network from computer or gateway over USB, Ethernet, WiFi and more interfaces is easy with DSH101 series sensor hub device which may accept up to 50 sensor devices. This sensor series is also supported by SimplHub bundle in DG100 Smart Edge IoT Gateway.

Based on physical and network layers of open source SimplicTI protocol this series of wireless sensors offers more by adopting Simpl (Simplified Modbus Protocol Layer) as application layer. This approach offers unified memory based application model of sensor which is usable for different application. Adding new primitives of indication and confirmation together with existing request and response, make this protocol ideal for bidirectional communication in low power wireless and actuator network.

measured Physical quantities

Different sensor types are available with several physical quantities. Some devices are single physical quantity sensor while others are combining multiple quantities in a single device. Sensor name consists of sensor family name and sensor type number. For example DWS101 is name for DWS100 series NTC temperature sensor with 01 sensor type number.
