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。Your 5V system can wield great power with this big, beefy relay board. How does 10A on the NC contacts and 20A on the NO contacts at 220VAC sound? The SparkFun Beefcake Relay Control Kit contains all the parts you need to get your high-power load under control. Only minimal assembly is required!。The heart of the board is sealed, SPDT 20A/10A Relay. The relay is controlled by 5V logic through transistor, and an LED tells you when the relay is closed. This is kit, so it comes as through-hole parts with assembly required, which makes for some nice soldering practice. Screw terminal connectors on either side of the board make it easy to incorporate into your project.。There are some pretty beefy traces connecting the relay to the load pins, but the 3-pin terminals are only rated for 15A max! If you plan on connecting larger load, you'll need to solder directly to the board. As always with high current and voltage, play it safe and use your judgment when deciding how much of load you want to put on board -- in open airflow the PCB can handle the full 20A for few minutes at time, but in an enclosed area heat can build up.。Note:Please keep in mind that this board is really meant for someone with experience and good knowledge of electricity. If you're uncomfortable soldering or dealing with high voltage, please check out the IoT Power Relay. The IoT Power Relay is fully enclosed, making it lot safer.。Get Started With the Beefcake Hookup Assembly Guide。Features。Voltage Rating:220VAC/28VDC。VCC requirements:4-6V, 150mA capable。SPDT pins exposed(Form C)。14 AWG screw terminals for relay connections.。10 AWG solder lugs for relay connections.。Flyback diode included。Zener recovery diode included(decreases turn-off time)。Heavy oz. copper on PCB
