。Description。Passive Infrared(PIR)sensors are great for detecting motion in a small area around the sensor. The 170μA SparkFun EKMC4607112K PIR Breakout is a simple board equipped with an EKM-series PIR sensor from Panasonic(R). The EKM-series PIR sensors are optimized for small movements to offer motion-sensing options for continuously powered applications.。PIR sensors do not return specific distance data but instead monitor for IR light coming from objects in their field of view and will activate their signal when motion is detected in their sensing area， making them perfect for applications such as turning devices on automatically when motion is detected. Applications include home and building automation for energy saving， automated on/off lighting control， security， appliances， and IoT.。Panasonic's low-profile PIR motion sensors(10.9mm versus standard 14.4mm height offer space savings for constrained designs)consist of a lens to create various detection zones， an optical filter to block non-infrared light， pyroelectric sensing elements， electromagnetic shielding to all circuitry， and an impedance converter to get an electrical signal. This PIR sensor offers digital output across 32 zones at 5m detection distance with 90°×90° detection area.。Note：The sensitivity of passive infrared sensors is influenced by environmental conditions， so a performance evaluation test under representative conditions is recommended.。Get Started with the SparkFun PIR Breakout Guide。Features。Operating Voltage：2.3。-。4.0V。170 μA。standby current consumption。Lens diameter - 10.4mm。Lens Height - 10.9mm。5m detection distance。90°×90°(±45°)detection area

Description。The PQ12 series of micro linear actuators are ideal for applications requiring precise positioning and compact size. Weighing in at just 22 grams， the PQ12 is incredibly light as well as compact. The affordably-priced PQ12 is the most powerful actuator of it's size. This is why it has become a popular choice for OEM manufacturers as well as Arduino and RC hobbyists. Some industries where the PQ12 are in use include：prosthetics， robotics， medical， simulation.。The PQ12-R series of linear servos operate as a direct replacement for standard rotary servos. They use the same standard 3 wire connector， ground power and control. Regardless of how you drive your servos， be it with an RC receiver， an Arduino board， or a VEX micro-controller， the PQ12-R servo will function in place of a regular servo， but with the added benefit of providing linear motion. The PQ12-R is available in a 20mm stroke coupled with gear ratio options of 30：1， 63：1 and 100：1 cover a large variety of applications.。The PQ12-100-6-R has：a 100：1 gear ratio for maximum lifting force； 6VDC operating voltage； and a servo(PWM)interface. This powerful little actuator can lift 50N(～5kg)!。The datasheet doesn't mention a minimum operating voltage， but we've tested this actuator at 5VDC and it seems to work just fine. The maximum force and movement speed are reduced of course.。Features。Gearing Option：100：1。Peak Power Point：40N @ 6mm/s。Peak Efficiency Point：20N @ 8mm/s。Max Speed(no load)：10mm/s。Max Force(lifted)：50N。Max Side Load：10N。Back Drive Force：35N。Stroke：20 mm。Input Voltage：6 VDC。Stall Current：550mA @ 6V。Mass：22g。Operating Temperature -10℃ to +50℃。Positional Repeatability：±0.1mm。Mechanical Backlash：0.25 mm。Audible Noise：55dB @ 45cm。Ingress Protection：IP-54。Maximum Duty Cycle：20%。PWM(Servo)signal：Fully retracted：2.0ms @ 50Hz。Fully extended：1.0ms @ 50Hz

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. These items will need to be purchased separately from the Hookup Accessories below.。Get Started With the SparkFun RTK Surveyor Guide。Features。GNSS Receiver：ZED-F9P。Concurrent reception of GPS， GLONASS， Galileo and BeiDou。Receives both L1C/A and L2C bands。Current：68mA - 130mA(varies with constellations and tracking state)。Time to First Fix：25s(cold)， 2s(hot)。Max Navigation Rate：PVT(basic location over UBX binary protocol)- 25Hz。RTK - 20Hz。Raw - 25Hz。Horizontal Position Accuracy：2.5m without RTK。0.010m with RTK。Max Altitude：50km(31 miles)。Max Velocity：500m/s(1118mph)。Bluetooth(R)Transceiver：ESP32 WROOM。Xtensa(R)dual-core 32-bit LX6 microprocessor。Up to 240MHz clock frequency。16MB of flash storage。520kB internal SRAM。Integrated 802.11 BGN WiFi transceiver。Integrated dual-mode Bluetooth(R)(classic and BLE)。Hardware accelerated encryption(AES， SHA2， ECC， RSA-4096)。2.5 μA deep sleep current。Overall Device。Internal Battery：LiPo 1000mAh with 500mA charging。Radio Port：3.3V TTL Serial(57600bps RTCM TX/RX)。Data Port：3.3V TTL Serial(115200bps NMEA)。Weight：132g(entire device including battery)。Dimensions：118mm×79mm×30mm(4.7in×3.1in×1.2in)。1x Qwiic Connector。1x microSD Socket for optional logging。Changes：This version(which replaces SPX-17369)uses a reinforced edge mount SMA connector for better resiliency when a fixed 'stub' antenna is used.
