    DFRobot DFRobot Gravity - Lightning Distance Sensor

    The embedded man-made disturber rejection algorithm can effectively avoid the electrical interference generated by various household appliances. In addition to allowing general weather enthusiasts to measure local thunderstorm data simply and efficiently, thanks to its compact size and wide detection range, it can also be embedded in various smart wearable devices for an outdoor climber or people who work at heights.This provides early warning of thunderstorms that people can perceive so that people can take precautions a step ahead. The sensor can also be embedded in the indoor protection device inside lightning-sensitive equipment, and automatically trigger these devices to switch to the backup power to isolate the power grid when lightning strikes. At the moment of lightning, the interrupt pin IRQ generates a pulse. This can be used to trigger the shutter to open, helping photographers to accurately capture the exciting moment of lightning.The maximum estimated distance of lightning strike is 40km. Limited by the inherent measurement method and algorithm, the distance estimation resolution is 1~4km, 40 km in 15 steps.Features Lightning detection within 40km in 15 steps Lighting intensity detection Used both indoors or outdoors Embedded man-made disturber rejection algorithm Applications Consumer Weather Station (thunderstorm measurement) Wearable Devices (outdoor thunderstorm early warning) Lightning Photography Specification Input Voltage : 3.3 V - 5.5 V Maximum Detection Range: 40 km Distance Detection Resolution: 1 km - 4 km Intensity Detection Resolution: 21 bits, i.e. 0 ~16777201 I2C Address: Three options 0x03, 0x02, 0x01 Interface: Gravity I2C (logic level: 0-VCC) Dimension: 30 mm x 22 mm For more information, check out the DFRobot Gravity – Lightning Distance Sensor wiki page here.

  •  -20% DFRobot Bluno – Arduino-compatibel Board met Bluetooth 4.0

    DFRobot DFRobot Bluno - Arduino-compatibel Board met Bluetooth 4.0

    Bluno is de eerste in zijn soort die Bluetooth 4.0 (BLE) module integreert in Arduino Uno, waardoor het een ideaal prototyping platform is voor zowel software- als hardware-ontwikkelaars om BLE te gaan gebruiken. Je zult in staat zijn om je eigen slimme armband, slimme stappenteller, en nog veel meer te ontwikkelen. Door de low-power Bluetooth 4.0 technologie, kan real-time low energy communicatie heel eenvoudig worden gemaakt.Bluno integreert een TI CC2540 BT 4.0 chip met de Arduino UNno. Het maakt draadloos programmeren via BLE mogelijk, ondersteunt Bluetooth HID, AT commando om BLE te configureren en je kunt BLE firmware eenvoudig upgraden. Bluno is ook compatibel met alle 'Arduino Uno' pinnen wat betekent dat elk project gemaakt met Uno direct draadloos kan gaan! Specificaties On-board BLE chip: TI CC2540 Draadloze programmering via BLE Ondersteunt Bluetooth HID Support AT commando om de BLE te configurerenTransparante communicatie via seriële Gemakkelijke upgrade van BLE-firmware DC-voeding: USB-voeding of externe 7~12 V DC Microcontroller: Atmega328 Bootloader: Arduino Uno (ontkoppel elk BLE-apparaat voordat u een nieuwe schets uploadt) Compatibel met de Arduino Uno pin mapping Afmeting: 60 x 53 mm (2.36 x 2.08') Gewicht: 30 g
