Description。This sealed digital temperature probe lets you precisely measure temperatures in wet environments with a simple 1-Wire interface. The DS18B20 provides 9 to 12-bit(configurable)temperature readings over a 1-Wire interface， so that only one wire(and ground)needs to be connected from a central microprocessor. Power for reading， writing， and performing temperature conversions can be derived from the data line itself with no need for an external power source.。Because each DS18B20 contains a unique silicon serial number， multiple DS18B20s can exist on the same 1-Wire bus. This allows for placing temperature sensors in many different places. Applications where this feature is useful include HVAC environmental controls， sensing temperatures inside buildings， equipment or machinery， and process monitoring and control.。Note：The pinout for this sensor is as follows：RED=Vcc BLACK=GND WHITE=SIG。Features。3.0-5.5V input voltage。-55℃ to +125℃ temperature range。±0.5℃ accuracy from -10℃ to +85℃。Waterproof。1 Wire interface。Probe is 7mm in diameter and roughly 26mm long. Overall length(including wire)is 6 feet.。Thermometer resolution is programmable from 9 to 12 bits.。Electrical performance：no flicker or breakdown within AC 1200V/1S ，within DC 500V theinsulation resistance shall be greater than 100MΩ

Description。The SparkFun Load Sensor Combinator is a bare PCB that combines four load sensors into a standard four-wire Wheatstone bridge configuration. If you open up an electronic bathroom scale， you'll find a large rat's nest of wires. The Load Sensor Combinator was created to combine the 12 wires found in a bathroom scale into the standard four-wire Wheatstone bridge configuration.。This version of the SparkFun Load Sensor Combinator features a few changes that you specifically asked for! We updated the silk on the breakout to read "C/+/-" instead of "R/W/B" and moved the temperature sensor connector away from the standoff hole.。You can either use four individual load sensors or simply purchase an off-the-shelf bathroom scale and hack the combinator into it rather than trying to design a base to properly mount four load sensors.。This board works great with our Load Cell Amplifier breakout board； the five pins on the edge of the combinator line up directly to the five pins on the amplifier.。If your amplifier and supporting electronics are more than a few inches away from the scale， an RJ45 footprint is provided. The four Wheatstone pins(E+/E-/S+/S-)as well as the shield pin are connected to twisted pairs within a standard cheap Ethernet cable. This allows the amplifier board to be placed many feet away from the scale itself.。The combinator board also includes a footprint for the DS18B20 one-wire temperature sensor. This allows the user to gather the temperature of the scale in case there is a large variance between the scale and the amplifier. These three pins are accessed through the RJ45 connection as well， allowing remote temperature readings to be gathered over one twisted pair Ethernet cable.。NOTE：。The SparkFun Load Sensor Combinator will only work with 3 wire load sensors， it is not compatible with 4 wire load cells.
