Description。The SparkFun RTK Surveyor is an easy to use GNSS receiver for centimeter-level positioning. Perfect for surveying， this preprogrammed device can also be used for autonomous driving， navigation， asset tracking and any other application where there is a clear view of the sky. The RTK Surveyor can also be used as a base station. With the flick of a switch， two RTK Surveyors can be used to create an RTK system capable of 14mm horizontal positional accuracy. The built-in Bluetooth(R)connection via an ESP32 WROOM enables the user to use the RTK Surveyor with their choice of GIS application on a phone or tablet. The built in battery allows field use for up to four hours and is compatible with common USB battery banks.。This device can be used in four modes：GNSS Positioning(～30cm accuracy)。GNSS Positioning with RTK(1.4cm accuracy)。GNSS Base Station。GNSS Base Station NTRIP Server。In Position mode the device receives L1/L2 signals from a user-provided antenna and the high-grade GNSS receiver provides lat/long and altitude with accuracies around 300mm.。In Positioning with RTK mode the device receives L1/L2 signals from the antenna and correction data from a base station. The correction data can be obtained from a cellular link to online correction sources or over a radio link to a 2nd RTK Surveyor setup as a base station.。In Base Station mode the device is mounted to a temporary position(like a tripod)and begins transmitting correction data over a radio or internet connection. A base is often used in conjunction with a second unit set to 'Positioning with RTK' to obtain the 14mm relative accuracy.。In Base Station NTRIP Server mode the device is mounted to a semi or permanently fixed position(like a roof)and connects over WiFi to transmit the correction data to a NTRIP caster so that any rover can access the correction data over a cellular or internet connection. This type of base is a very easy way to setup a very precise absolute correction source.。Two cables are provided with the RTK Surveyor allowing a user to plug on our easy to use Serial Telemetry Radios or their own radio link. If a local correction source is within 10km， a user can also use their phone to provide correction data over the Bluetooth(R)link(no external radio needed!).。Note：The SparkFun RTK Surveyor is just the enclosed device and does NOT include an antenna， serial telemetry radio， or associated mounting pieces.

Description。The SparkFun RTK Express is an easy to use GNSS receiver for centimeter-level positioning. Perfect for surveying， logging， and all types of post processing， this preprogrammed device can also be used for autonomous driving， navigation， asset tracking and any other application where there is a clear view of the sky. The RTK Express can also be used as a base station. With the press of a button， two RTK Expresses can be used to create an RTK system capable of 14mm horizontal positional accuracy. The built-in Bluetooth(R)connection via an ESP32 WROOM enables the user to use the RTK Express with their choice of GIS application on a phone or tablet. The built in battery allows for over five hours of field use and is compatible with common USB battery banks.。We took all the lessons from the RTK Surveyor and built the RTK Express. The RTK Express is built upon the same ZED-F9P u-blox receiver as the original RTK Surveyor so you can expect the same incredible performance and rich feature set. The embedded display allows for immediate feedback of horizontal positional accuracy， satellites in view， logging status， survey-in status， battery level， Bluetooth(R)MAC， etc. The rocker switches found on the original have been replaced by keypad buttons. We increased the battery to 1300mAh for a longer run time. The internal switches have been replaced by a digital Mux allowing for some really exciting applications including event triangulation. More ESD protection was added to protect the RF path， and we even threw in an accelerometer for digital leveling in the field.。This device can be used in four modes：GNSS Positioning(～30cm accuracy)。GNSS Positioning with RTK(1.4cm accuracy)。GNSS Base Station。GNSS Base Station NTRIP Server。In Position mode the device receives L1/L2 signals from a user-provided antenna and the high-grade GNSS receiver provides lat/long and altitude with accuracies around 300mm.。In Positioning with RTK mode the device receives L1/L2 signals from the antenna and correction data from a base station.

Description。The MQ-9B is a CO and CH4 gas detection sensor form Winsen. The sensing material of the MQ-9B is SnO2， which has a low conductivity in clean air. It detects carbon monoxide(1.5V)by method of cycling high and low temperature. The sensor's conductivity gets higher with the CO and CH4 gas concentration rising. The sensing range is 10-500ppm CH4. A simple circuit makes measuring this change in conductivity and turning it into data fairly straight-forward， but does require some calibration.。For easy Solderability； use our Gas Sensor Breakout Board.

Description。The MQ-2 is a smoke and combustible gas sensor from Winsen. It can detect flammable gas in a range of 300 - 10000ppm. It's most common use is domestic gas leakage alarms and detectors with a high sensitivity to propane and smoke. The sensing material is SNO2 for which the conductivity is lower in clean environments and higher when smoke or flammable gas is present. A simple circuit makes measuring this change in conductivity and turning it into data fairly straight-forward， but does require some calibration.。For easy Solderability； use our Gas Sensor Breakout Board.

Description。The SparkFun ZOE-M8Q GPS Breakout is a high accuracy， miniaturized， GPS board that is perfect for applications that don't possess a lot of space. The on-board ZOE-M8Q is a 72-channel GNSS receiver， meaning it can receive signals from the GPS， GLONASS， BeiDou， and Galileo constellations. This increases precision and decreases lock time and thanks to the onboard rechargable battery you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally， this u-blox receiver supports I2C(u-blox calls this Display Data Channel)which made it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. Utilizing our handy Qwiic system， no soldering is required to connect it to the rest of your system. However， we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.。U-blox based GPS products are configurable using the popular， but dense， windows program called u-center. Plenty of different functions can be configured on the ZOE-M8Q：baud rates， update rates， geofencing， spoofing detection， external interrupts， SBAS/D-GPS， etc. All of this can be done within the SparkFun Arduino Library. We've also made sure to configure the UART pin grouping on the breakout to an industry standard to insure that it easily connects to a Serial Basic.。The SparkFun ZOE-M8Q GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the ZOE-M8Q. This reduces the time-to-first fix from a cold start(～30s)to a hot start(～1s). The battery will maintain RTC and GNSS orbit data without being connected to power for up to five hours. Since the ZOE-M8Q is a tiny GPS receiver and to minimize its footprint， we've added a U.FL connector to allow the use of both large standard ceramic antennas as well as very small chip scale antennas.。Note：The I2C address of the ZOE-M8Q is 0x42 and is software configurable. A multiplexer/Mux is required to communicate to multiple ZOE-M8Q sensors on a single bus. If you need to use more than one ZOE-M8Q sensor consider using the Qwiic Mux Breakout.。The SparkFun Qwiic Connect System is an ecosystem of I2C sensors， actuators， shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch， 4-pin JST connector. This reduces the amount of required PCB space， and polarized connections mean you can't hook it up wrong.。The ZOE-M8Q GPS Breakout can also be automatically detected， scanned， configured， and logged using the OpenLog Artemis datalogger system. No programming， soldering， or setup required!。Get Started With the SparkFun ZOE-M8Q Hookup Guide。Features。72-Channel GNSS Receiver。2.5m Horizontal Accuracy。18Hz Max Update Rate。Time-To-First-Fix：Cold：26s。Hot：1s。Max Altitude：50，000m。Max G：≦4。Max Velocity：500m/s。Velocity Accuracy：0.05m/s。Heading Accuracy：0.3 degrees。Time Pulse Accuracy：30ns。3.3V VCC and I/O。Current Consumption：～29mA Tracking GPS+GLONASS。Software Configurable。Geofencing。Odometer。Spoofing Detection。External Interrupt。Pin Control。Low Power Mode。Many others!。Supports NMEA， UBX， and RTCM protocols over UART or I2C interfaces
