DescriptionThe TFMini Plus is a ToF(Time of Flight)LiDAR sensor capable of measuring the distance to an object as close as 10 centimeters(+/- 5cm up to 6m)and as far as 12 meters(+/-1% starting at 6m)! As with all LiDAR sensors， your effective detection distance will vary depending on lighting conditions and the reflectivity of your target object， but what makes this sensor special is its size. Measuring only 35x18.5x21mm， the TFMini Plus allows you to integrate LiDAR into applications traditionally reserved for smaller sensors.Setting itself apart from the original TFmini， the TFmini Plus has been designed with an IP65 enclosure meaning its "Dust tight water resistant"， and also passed the vibration test of drone level， which will greatly expand its application range. The TFMini Plus is easy to power at only 5V and easy to talk to using the UART communication protocol.Important：This product does not use laser light for ranging. Instead it contains an LED and optics. Many such systems are being marketed under the name "LiDAR，" although it may be more appropriate to think of this device as a "Time-of-Flight Infrared Rangefinder". It differs significantly from traditional IR rangefinders in that it uses ToF to determine range and not triangulation ― as is performed by the Sharp GP-series devices.FeaturesOperating Range - 0.1m～12m1Accuracy - ±5cm@(0.1-6m)， ±1%@(6m-12m)Distance resolution - 5mmFrame rate - 1-1000Hz(adjustable)Ambient light immunity - 70kluxOperating temperature - -20℃～60℃Enclosure rating - IP65Light source - LEDCentral wavelength - 850nmFOV - 3.6°Supply voltage - 5V±0.5VAverage current - ≦110mAPower consumption - 550mWPeak current - 500mACommunication level - LVTTL(3.3V)Material of enclosure - ABS+PCStorage temperature - -20℃～75℃Weight - 11gWire length - 30cm

DescriptionThe SparkFun Pulse Oximeter and Heart Rate Sensor is an I2C based biometric sensor， utilizing two chips from Maxim Integrated：the MAX32664 Biometric Sensor Hub and the MAX30101 Pulse Oximetry and Heart Rate Module. While the latter does all the sensing， the former is an incredibly small and fast Cortex M4 processor that handles all of the algorithmic calculations， digital filtering， pressure/position compensation， advanced R-wave detection， and automatic gain control. We've provided a Qwiic connector to easily connect to the I2C data lines but you will also need to connect to two additional lines. This board is very small， measuring at 1in×0.5in(25.4mm×12.7mm)， which means it will fit nicely on your finger without all the bulk.The MAX30101 does all the sensing by utilizing its internal LEDs to bounce light off the arteries and arterioles in your finger's subcutaneous layer and sensing how much light is absorbed with its photodetectors. This is known as photoplethysmography. This data is passed onto and analyzed by the MAX32664 which applies its algorithms to determine heart rate and blood oxygen saturation(SpO2). SpO2 results are reported as the percentage of hemoglobin that is saturated with oxygen. It also provides useful information such as the sensor's confidence in its reporting as well as a handy finger detection data point. To get the most out of the sensor we've written an Arduino Library to make it easy to adjust all the possible configurations.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.

DescriptionPassive 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 GuideFeaturesOperating Voltage：2.3-4.0V170 μAstandby current consumptionLens diameter - 10.4mmLens Height - 10.9mm5m detection distance90°×90°(±45°)detection area

DescriptionThis straight bar load cell(sometimes called a strain gauge)can translate up to 10kg of pressure(force)into an electrical signal. Each load cell is able to measure the electrical resistance that changes in response to， and proportional of， the strain(e.g. pressure or force)applied to the bar. With this gauge you will be able to tell just how heavy an object is， if an object's weight changes over time， or if you simply need to sense the presence of an object by measuring strain or load applied to a surface.Each straight bar load cell is made from an aluminum-alloy and is capable of reading a capacity of 10kg. These load cells have four strain gauges that are hooked up in a wheatstone bridge formation. The color code on the wiring is as follows：red = E+， green = O+， black = E-， and white = O-. Additionally， these load cells offer an IP66 protection rating and feature two M4 and two M5 sized through-holes for mounting purposes.Get Started with the Load Cell GuideFeatures80mm×12.7mm×12.7mm， 250mm Wire
