Device Overview The UM6 Ultra-Miniature Orientation Sensor combines sensor measurements from rate gyros, accelerometers, and magnetic sensors to measure orientation at 500 Hz. The UM6 also has the capability to interface with external GPS modules to provide position, velocity, course, and speed information. Communication with the UM6 is performed over either a TTL (3.3V) UART or a SPI bus. The UM6 is configured by default to automatically transmit data over the UART. The UM6 can be configured to automatically transmit raw sensor data, processed sensor data, angle estimates, and angle estimate covariances at user configurable rates ranging from 20 Hz to 300 Hz in roughly 1 Hz increments. The UM6 can also receive and parse GPS packets, automatically transmitting new GPS position, velocity, and satellite data whenever it is available. Alternatively, the UM6 can operate in "silent mode," where data is transmitted only when specific requests are received over the UART. Regardless of the transmission mode and rate, internal angle estimates are updated at 500 Hz to improve accuracy. The UM6 simplifies integration by providing a number of automatic calibration routines, including rate gyro bias calibration, magnetometer hard and soft iron calibration, and accelerometer "zeroing" to compensate for sensor-platform misalignment. All calibration routines are triggered by sending simple commands over the serial interface. The UM6 comes factory-calibrated to remove soft and hard iron distortions present in the enclosure. When integrated into the end-user system, additional calibration may be necessary to correct other magnetic field distortions. Magnetometer calibration can be performed using the UM6 interface software, available for free download from www.chrobotics.com/downloads. Temperature compensation of rate gyro biases is also supported by the UM6. An internal temperature sensor is used to measure temperature, and third-order compensation is applied to remove the effects of temperature-induced bias. By default, the terms used in compensation are all zero, which means that no temperature compensation is performed. The compensation terms must be determined experimentally by the end-user. On special request, compensation can be performed on each device at the factory. The UM6 can be configured to use either Euler Angles or quaternions for attitude estimation. In Euler Angle mode, magnetometer updates are restricted to yaw alone. This can be useful in cases where distortions are possible or even expected, and where it would be undesirable for those distortions to affect pitch and roll angles (i.e. on a flying rotorcraft). In quaternion mode, Euler Angles are still available, but there are no restrictions on what angles the magnetometer is allowed to influence. The UM6 is available in an OEM version (the UM6-LT) that has a slightly larger footprint and does not include an enclosure. The UM6-LT is functionally equivalent to the UM6, but magnetometer calibration is not performed at the factory.
The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile userprogrammable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of -55°C to +125°C and is accurate to ±0.5°C over the range of -10°C to +85°C. In addition, the DS18B20 can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply. User-Definable Nonvolatile (NV) Alarm Settings Alarm Search Command Identifies and Addresses Devices Whose Temperature is Outside Programmed Limits (Temperature Alarm Condition) Available in 8-Pin SO (150 mils), 8-Pin µSOP, and 3-Pin TO-92 Packages Software Compatible with the DS1822 Applications Include Thermostatic Controls, Industrial Systems, Consumer Products, Thermometers, or Any Thermally Sensitive System PIN CONFIGURATIONS MAXIM 18B20 1 N.C. 2 VDD 3 DQ 1 2 3 N.C. 8 4 N.C. 7 N.C. 6 N.C. 5 MAXIM 18B20 Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many DS18B20s distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment, or machinery, and process monitoring and control systems.
