VERVIEW 2.1. Sensor Overview The wireless sensors designed and manufactured by Radio Bridge provide full sensor to cloud solutions for Internet of Things (IoT) applications. The high-precision tilt sensor uses an accelerometer to detect the angle from a 0-degree vertical orientation. When the sensor is tilted either away from or toward the vertical orientation by a specified amount, an alert is sent to the wireless network.
If the standard Radio Bridge console (console.radiobridge.com) is not used, refer to this section to decode the sensor data and configure the sensor through downlink messages. 6.1. Common Messages There are common messages across all wireless sensors that are defined in the document “Common Sensor Messages”...
IRELESS RECISION ENSOR 6.2. Uplink Messages The uplink message (sensor to web application) specific to the sensor is defined in following table. The common uplink messages are not included in this section (see common messages document). Table 5 Uplink Message 0x0F: High-Precision Tilt Event Byte Description 0x00...
IRELESS RECISION ENSOR The report-on-change messages are sent when the tilt angle increases away from vertical or decreases back to vertical a specified amount from the last report. For example, consider a report-on-change value that is set to 5 degrees and the current angle from the vertical axis is 15 degrees.
IRELESS RECISION ENSOR The shape and magnitude of the temperature-dependence curve will be different depending on the orientation of the sensor. Thus, this curve alone should not be used for temperature compensation. 6.3. Downlink Messages The downlink message (web application to sensor) specific to the sensor configuration is defined in following table.
IRELESS RECISION ENSOR Period defined in minutes (1-127 minutes) For example, to receive a report every 4 hours, byte 1 would be set to 0x04. To receive a periodic report every 15 minutes, byte 1 would be set to 0x8f. Periodic reporting is not recommended as it will increase data service fees and significantly reduce battery life.
IRELESS RECISION ENSOR Table 9 Threshold Mode Bytes for Configuration Message 0x0F Bytes Description Angle for transition away from the 0-degree vertical state, whole integer value. Default 55 degrees Angle for transition away from the 0-degree vertical state, fractional value Angle for transition toward the 0-degree vertical state, whole integer value.

IRELESS RECISION ENSOR Angle for report-on-change mode toward the 0-degree vertical position, fractional value. Since the high-precision tilt sensor has precision to 0.1 degrees, the angles are defined by both an integer value and a fractional value. For example, to define an angle of 16.8 degrees, the values would be 0x10 and 0x08 respectively.
