Read and understand all instructions. Failure to follow all instructions listed below may result in electric shock, fire and/or serious personal injury. • SAVE THESE INSTRUCTIONS • WORK AREA • Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents. • Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes. • Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control. • ELECTRICAL SAFETY • Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adaptor plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tools should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user. Applicable only to Class I (grounded) tools. • Double insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double insulation eliminates 1 the need for the three wire grounded power cord and grounded power supply system. Applicable only to Class II (double insulated) tools. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded. Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock. Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock. When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W.” These cords are rated for outdoor use and reduce the risk of electric shock. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord. Minimum Gage for Cord Sets Volts Total Length of Cord in Feet ...

Datasheet SHT1x (SHT10, SHT11, SHT15) Humidity and Temperature Sensor: Fully calibrated Digital output Low power consumption Excellent long term stability SMD type package – reflow solderable Product Summary Each SHT1x is individually calibrated in a precision humidity chamber. The calibration coefficients are programmed into an OTP memory on the chip. These coefficients are used to internally calibrate the signals from the sensors. The 2-wire serial interface and internal voltage regulation allows for easy and fast system integration. The tiny size and low power consumption makes SHT1x the ultimate choice for even the most demanding applications. Dimensions Sensor Chip 1.5 ±0.2 2.0 ±0.1 1.5 ±0.1 sensor opening 1 2.5 ±0.1 NC 4 A5Z 11 Material Contents NC NC 2.2 MAX 2 5.2 ±0.2 4.2 ±0.1 1.27 ±0.05 NC 3 1.83 ±0.05 7.47 ±0.05 NC SHT1x is supplied in a surface-mountable LCC (Leadless Chip Carrier) which is approved for standard reflow soldering processes. The same sensor is also available with pins (SHT7x) or on flex print (SHTA1). SHT1x V4 – for which this datasheet applies – features a version 4 Silicon sensor chip. Besides a humidity and a temperature sensor the chip contains an amplifier, A/D converter, OTP memory and a digital interface. V4 sensors can be identified by the alpha-numeric traceability code on the sensor cap – see example “A5Z” code on Figure 1. 0.6 ±0.1 0.95 ±0.1 SHT1x (including SHT10, SHT11 and SHT15) is Sensirion’s family of surface mountable relative humidity and temperature sensors. The sensors integrate sensor elements plus signal processing on a tiny foot print and provide a fully calibrated digital output. A unique capacitive sensor element is used for measuring relative humidity while temperature is measured by a band-gap sensor. The applied CMOSens® technology guarantees excellent reliability and long term stability. Both sensors are seamlessly coupled to a 14bit analog to digital converter and a serial interface circuit. This results in superior signal quality, a fast response time and insensitivity to external disturbances (EMC).

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.
