Environmental

Introduction/Additional information: 

12.1 This message provides environmental information from 1 to 8 sensor reports (e.g., 1 sensor report uses 2 slots while a message with 8 sensor reports can use up to 5 slots). Each sensor report carries the dynamic or static information relating to a specific sensor.

12.2 Each Environmental Message has 56 bits of standard header, with 12 bits available for payload. Each sensor report has 27 bits of common data leaving 85 bits for sensor data. Table 12.3 provides the framework for the sensor report.

12.2.1 Table 12.4 outlines a variety of sensor types that can be transmitted using this message.

12.2.2 The sensor data is defined in accordance to the sensor type. Tables 12.5 to 12.15 provide details for the 85 bits of information for each sensor report type. In each case "Sensor not available" means that the specific reading is not ever possible from that sensor location and "Data not available" means that the reading is possible but is not available for the current report (i.e. the sensor could be malfunctioning).
