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 LIDAR-Lite v4 LED sensor is the next step in the LIDAR-Lite line. A small， lightweight， low-power optical ranging sensor. It's the first to incorporate ANT profile wireless networking technology into an optical sensor. Its built-in nRF52840 processor means that developers can create custom applications， or be operated as a stand-alone device right out of the box by using the preloaded stock application.Like the LIDAR-Lite v3 and LIDAR-Lite v3HP sensors； it can also be directly connected to an external micro-controller running a custom user application. As such， it provides a highly adaptable option for OEM and maker applications in robotics， Internet of Things， and unmanned vehicles ― or any application where an ultrasonic sensor might otherwise be used. It's perfect as the basic building block for applications where wireless capabilities， small size， light weight， low power consumption and high performance are important factors in a short-range， 10-meter， optical distance measuring sensor.The LIDAR-Lite v4 requires an external 5VDC power source and soldering is required. This Time-of-Flight ranging module uses a LED and optics for ranging. It does not use a laser； therefore， it is inherently eye-safe under normal usage.FeaturesResolution：1 cmMeasurement repeatability：As measured indoors to a 90% reflective target1 cm is equivalent to 1 standard deviationUsing "high accuracy" mode， with averaging：+/- 1 cm to 2 meters+/- 2 cm to 4 meters+/- 5 cm to 10 metersRange：5 cm to 10 meters(as measured from back of unit)Update rate：I2C = >200 Hz typicalANT(R)= up to 200 Hz to a 90% target indoors at 2m in normal operating modeInterface：I2C or ANT； user configurable for SPI using the Nordic SDKPower(operating voltage)：4.75 - 5.25 VDCCurrent consumption：2mA idle， 85mA during acquisitionOperating temperature：-20 to 60° CLED wavelength：940 nmBeam divergence：4.77°Optical aperture：14.9 mmUnit size(HxWxD)：2.1"×0.8"×0.9"(52.2×21.2×24.0 mm)Weight：14.6 g(0.5 oz)

DescriptionThe SparkFun Line Follower Array is a long board consisting of eight IR sensors that have been configured to read as digital bits! We have designed the SparkFun Line Follower Arrays to follow a dark line of about 3/4 inch width or smaller(spray paint or electrical tape)on a light background. Each array features visible LEDs that point upward when the board is attached(properly)so you can see what the robot sees， brightness control right on the board， and an I2C interface for reading and power control. Here at SparkFun， the RedBot Shadow Chassis was used as a test platform but really this was designed as an add-on for almost any bot.The line follower functions by taking an 8-bit reading of reflectance for use with following lines or reading dark/light patterns and can see from about 1/4 to 3/4 inches away. The IR brightness control and indicator can be adjusted with the on-board potentiometer and is capable of showing you the strength of the IR LEDs. Illumination can be turned on and off with software to conserve power， or left on all the time for faster readings. The SparkFun Line Follower Array requires 5V of power with a supply current range of 25-185mA with strobing disabled and 16-160mA with it enabled. Additionally we have added six mounting holes to the line follower with the two inner holes designed to fit our Shadow Chassis while the other four are general purpose.Note：As you know our Sun emits quite a bit of infrared light， making the SparkFun Line Follower Array much less effective in direct sunlight. Plan your projects accordingly!Features8 sensor eyes(QRE1113， like in our line sensor breakout)I2C interfaceAdjust IR brightness on the fly with a knobSwitch IR on and off with softwareSwitch visual indicators on and off with softwareInvert dark/light sight with softwareBased on the SX1509 I/O expander

DescriptionThe TFMini-S Micro LiDAR Module is a ToF(Time of Flight)LiDAR sensor capable of measuring the distance to an object as close as 10 centimeters(+/- 6cm 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 42x15x16mm， the TFMini-S allows you to integrate LiDAR into applications traditionally reserved for smaller sensors.TFMini-S is a single-point ranging LiDAR based on TFmini upgrade. The blind zone is shortened to 10cm， the outdoor performance and accuracy of different reflectivity are improved， it can achieve stable， accuracy， sensitive and high frequency range detection.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～12m@90%Reflectivity0.1～7m@10% Reflectivity0.1m～12m@90%Reflectivity(70Klux)0.1～7m@10% Reflectivity(70Klux)Accuracy：±6cm@(0.1-6m)±1%@(6m-12m)Distance Resolution：1cmFrame Rate：100HzAmbient light immunity：70KluxOperating Temperature：0℃～60℃Light source：VCSELCentral wavelength：850nmPhotobiological safety：Class1(EN60825)FOV：2°2Supply voltage：5V±0.1VAverage current：≦140mAPower consumption：≦0.7WPeak current：200mACommunication level：LVTTL(3.3V)Communication interface：UART / I2CDimension：42mmx15mmx16mm(LxWxH)Housing：PC/ABSStorage temperature：-20℃～75℃Weight：5g±0.3gCable length：10cm
